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 sustaining
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 customers product
compliance to IEEE C62.41.2 Location Category C High and
US Dept of Energy MSSLC Model Spec.

Surge Protection Module
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.
10. LSP10480* passed Operational Voltage Test (552Vac, 30 minutes) based on UL 1449 4th edition clause 43.

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.
