Technical data – Trigger action actuators
22.5mm Pushbuttons, Indicating Lights and
Selector Switches
Description
The E22LTA2 is a latching, trigger-action, twist-to-release pushbutton
actuator designed specifically for use as an Emergency Stop Switch.
The E22MGTA is a rectangular guard designed to prevent accidental or
inadvertent actuation of the E22TLA actuator. It is also designed to permit
easy knob rotation access for manually resetting the switch.
The E22CB1, E22CB11 & E22CB1E contact blocks are specially marked
contact blocks indicating compliance with IEC 60947-5-1 Annex K.
Application
The E22LTA2 actuator and E22CB* contact blocks are intended to be the
primary and/or one of several series-connected emergency stop switches in
a control panel. The N.C. (normally closed), break electrical contacts are
D.O.A. (direct opening action) which are designed to be forcibly opened by
the movement of the actuator in the event that the contact should be tack
welded etc.
Key features
✮Mushroom head button (40mm diameter) for easy actuation (per EN418
Section 4.4).
✮Safety red coloured button per ANSI Z535.1 and EN418 Section 4.4.3.
✮Manually resettable actuator.
✮Rectangular guard is coloured safety yellow per ANSI Z535.1 and
provides yellow background for the actuator per EN418 Section 4.4.3.
✮All external pushbutton and guard materials have a V-0 flammability
rating per UL94.
✮Contact blocks are A600/Q600 rated per UL508 and AC15/DC13 rated per
IEC 60947-5-1.
N.C. (normally closed), break contact blocks are positive opening or
D.O.A. (direct opening action) in accordance with EN418 Section 4.1.2.
✮Suitable for isolation per IEC 60947-5-1.
Environmental ratings (actuator)
Ingress protection
UL (NEMA) 1, 2, 3, 3R, 4, 4X, 12 & 13 and IEC IP 65 when mounted on a
flat surface of a similarly rated enclosure. Above ratings do not apply to
applications where devices are mounted directly unto a machine without
the use of a separate console or enclosure. If not installed in a suitable
panel or enclosure, precautions must be taken to safeguard contact blocks
against electrical contact or shock and from contamination from
environmental or working conditions of the machine.
