APL/UPL APL/UPL Series "Existing Design-In Only" APL/UPL Series Hydraulic Magnetic Circuit Protectors INTRODUCTION IMPORTANT NOTICE: The APL/UPL is a legacy product and no new design-in orders are being accepted. We are also discontinuing the 205 series (APL with dust proof enclosure). If the specifications for any of these products are necessary for your system, Sensata Technologies recommends utilizing the AirpaxTM IAL series. presence of an overload, even though the handle is held in the ON position. The APL/UPL magnetic circuit protector provides reliable, low-cost power switching, circuit protection and circuit control. The handle opens and closes a circuit, under normal load conditions, similar to an ON-OFF switch. Upon overload, the internal mechanism trips, opens the contacts and forcibly returns the handle to the OFF position. Since the protector is "trip free," the internal contacts will not remain closed in the While designed for industrial, military and information processing applications, the APL is suitable for use in any situation where precision operation is required. Most versions of the APL family are recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2-No. 235 as supplementary protectors and are designated with the UPL prefix. APL/UPL Single Pole Toggle The APL/UPL line offers many configurations including series, shunt and relay with a choice of delays and ratings. APL/UPL multi-pole assemblies are available with a mix of current ratings, delays and internal circuit configurations. 2.020 MAX. [51.31] .150 [3.81] 2.530 MAX.

APL/UPL MULTI-POLE CIRCUIT PROTECTORS Mounting Details Multi-pole protectors are combined in an assembly with the actuating handles linked and the trip mechanisms internally coupled. A fault in either protected circuit opens all poles simultaneously. Applications include use in two-phase circuits, single-phase three-wire systems or in two or more related but electrically isolated circuits. A mix of delays, ratings and configurations is possible, with the series type having any of the auxiliary switches listed. Combinations up to nine poles are available.

APL/UPL CONFIGURATIONS Series Trip The most popular configuration for magnetic protectors is the series trip where the sensing coil and contacts are in series with the load being protected. The handle position conveniently indicates circuit status. In addition to providing conventional over-current protection, it's simultaneously used as an on-off switch. Auxiliary Switch (Applies to Series Trip Only) This is furnished as an integral part of a series pole in single or multi-pole assemblies. Isolated electrically from the protector's circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protector's on-off status. Auxiliary switch contacts actuate simultaneously with the main breaker contacts, and will open regardless of whether the breaker contacts are opened manually or electrically. For auxiliary switch ratings below 6Vac or 5Vdc, an auxiliary switch with gold contacts is available. Gold contacts are not recommended for load current above 100 milliamps. The contacts on our optional RS auxiliary switch will open only in the event of an electrical trip of the circuit breaker. Shunt Trip The shunt trip is designed for controlling two separate loads with one assembly. The control is established by providing overload protection for the critical load. When the current through this load becomes excessive and reaches the trip point, the protector will open and remove power from both loads simultaneously. The total current rating of both loads must not exceed the maximum contact rating. Relay Trip This permits the overload sensing coil to be placed in a circuit which is electrically isolated from the trip contacts. The coil may be actuated by sensors monitoring pressure, flow, temperature, speed, etc. Other typical applications include crowbar, interlock and emergency/rapid shutdown circuitry. Trip may be accomplished by voltage or current, which must be removed immediately upon tripping. Dual Coil Dual coil protectors provide remote shut down option and normal overcurrent protection in the confines of a single breaker pole. This construction saves space by eliminating the need for an additional pole for the voltage trip function. Voltage Trip Sometimes called "dump circuits" or "panic trip circuits," these units make it possible to open main power contacts with lower power inputs from one or more sources. This configuration is becoming increasingly more important for sensitive circuitry and denser packaging in automation systems. Available in series, shunt, relay or dual coil configurations.

The patented protector design provides both increased tolerance to high inrush induced nuisance tripping and longer trip times at 600 percent. These delays are ideally suited for applications where thermal devices are presently used, such as motor protection or where short duration, high inrush currents are experienced. As shown in a typical motor start-up curve, the delay 66 will provide locked rotor and overload protection. Nuisance tripping is avoided since acceptable short periods of overload will not trip the protector. 10000 1000 1000 DELAY 64 100 TIME IN SECONDS TIME IN SECONDS 100 10 1 10 1 .1 .1 .01 .01 .001 .001 0 100 150 200 125 300 400 500 600 700 800 900 1000 MAY TRIP 10000 1000 DELAY 66 100 10 1 .1 .01 .001 0 100 150 200 125 300 400 500 600 700 PERCENT OF RATED CURRENT 0 100 150 200 125 300 400 500 600 700 PERCENT OF RATED CURRENT PERCENT OF RATED CURRENT TIME IN SECONDS DELAY 65 MAY TRIP MAY TRIP 10000 800 900 1000 800 900 1000 APL/UPL DC/50/60Hz Delay Curves (typ) (Multi-frequency) A choice of delays is offered for combined DC and 50/60Hz operation.

The coding given permits a self-assigning part number; other configurations may require a factory assigned part number. Typical examples are units with mixed ratings, combinations of styles or constructions not listed in the third decision table, etc. With these, it is suggested that order entry be by description and/or drawings and a part number will be assigned. Additionally, it is a standard policy to establish a factory assigned part number wherever a descriptive drawing exists to provide cross reference, traceability and manufacturing control. When specifying a protector for AC motor start or high inrush applications, the peak amplitude and surge duration should be specified for factory assistance in rating selection. For example, the code shown is the code for a two pole UPL protector with series trip, 20 ampere rating, 50/60Hz. short time delay construction in all poles. To determine the ordering number for your particular APL/UPL unit, simply follow the steps shown. You may use this number to place an order or as a reference for further questions you may have. Notes: AThe most common current values for 100% of rated current are those listed. Please consult an Airpax office orsales representative for other values. B All APL/UPL protectors are constructed with stainless steel springs and plated parts. As noted in the specifications, all meet normal requirements for moisture and salt spray resistance. If fungus resistance is required in addition to moisture and salt spray resistance, special procedures and markings are employed. C Terminals will be supplied as #10-32 threaded studs up to 50 amperes. Above this amperage terminals will be 1/4-28 threaded studs. All standard units will be supplied with a hex nut and two flat washers on each threaded terminal. DWhen metric threaded inserts are specified, breakers rated at 50 amperes and below will be supplied with metric threaded terminals. For breakers rated above 50 amperes, 1/4 -28 threaded terminals will be supplied. E Black handle standard. APL/UPL UPL 11 - 1 - 61- 20 3
