Notes:

1. Self-declared compliance.

The Littelfuse LSP10 thermally protected Surge Protective

Device is a self-protected device which is specially designed

to be used in outdoor and commercial LED lighting ﬁxtures

for transient overvoltage protection. It is constructed with

Littelfuse thermally protected varistor technology. Its built-in

thermal disconnect function provides additional protection

to prevent catastrophic failure and ﬁre hazard even under

the extreme circumstances of varistor end-of-life or sustain-

ing over voltage conditions. LSP10 series connected option

allows clear indication of thermal fault protection by discon-

necting power to luminaire thereby signally SPD module

replacement. The LSP10 SPD facilitates customer’s product

compliance to IEEE C62.41.2 Location Category C High and

US Dept of Energy MSSLC Model Spec.

LED Lighting Surge Protection Module > LSP10

Notes:

1. 5A max. continuous current for series connection.

2. Nominal Discharge Current (In)(A): The nominal discharge current is a measure of the SPDs endurance capability; 15 impulses of discharge current uses the 8/20us current waveform.

3. Maximum Discharge Current (Imax)(A): The maximum discharge current is a measure of the SPDs maximum capability; single impulse of discharge current uses the 8/20us current waveform. All

Devices pass maximum discharge current with possible, safe opening of thermal disconnect.

4. MLV – UL1449 Measured limiting voltage; the highest value of residual voltage measurements during the application of impulses of 8/20us nominal discharge current (In); an average voltage value of

15 impulses.

5. Up – IEC 61643-11 Voltage protection level; the highest value of residual voltage measurements during the application of impulses of 8/20us nominal discharge current (In); a rounding voltage value of

maximum measurement.

6. MCOV/UC: Maximum Continuous Operating Voltage - maximum r.m.s. voltage that could be continuously applied to the SPD.

7. The series modules can be used in parallel connections for the indication circuit connection.

8. * = - P or PM

9. Repetitive Surge Withstanding: 15 strikes at 10,000A (8/20us) with steady MLV/Up.

Notes:

1. Series module used in parallel connection for indication circuit connection.

2. LED indicator and associated circuitry are not included in the module.

3. Black wire is AC line voltage (hot); white wire is AC neutral voltage.

4. Black wire voltage is cut off when SPD needs replacement.

5. R is current limiting resistor; it resistance/wattage is determined by AC line voltage and

desired current driving LED. Example: AC line voltage 240V, LED: 1.6mA, resistor:

150Kohm/0.5W.
