MODE OF OPERATION
The ICM495 is a UL Listed Electrical Disconnect with an Internal Surge
Protective Device built-in. The ICM495 is available in two models 30A
Fused and 60A Non-Fused.
The included Type 2 SPD is intended for 240 VAC Split Phase
configurations. When a surge occurs, the ICM495 will absorb the surge
up to the limits expressed in the specifications section in this guide.
The ICM495 incorporates thermal protection on the surge elements
(TMOV's) which allows for safe disabling of the surge elements when
a surge exceeds the thermal limits of the device. The ICM495 has a
status light on the control which identifies operational status when
illuminated. The ICM495 can be installed as a Type 2 device for both
indoor and outdoor applications. Suitable for use on a circuit capable
of delivering not more than 10kA RMS symmetrical amperes (Convient à
des circuits produisant au plus 10kA eff.).

DIAGNOSTICS AND MAINTENANCE
Periodically check the status on the SPD. If the green light is OFF, the
protection is no longer available and the unit needs to be replaced
immediately. This device features an internal protection that will
disconnect the surge protective component at the end of its useful life
but will maintain power to the load - now unprotected. 14 AWG stranded
copper wire or larger required. If any of the 30 Amp fuses blow on the
fused model, please replace the fuse or fuses with the appropriate 30
amp fuses. Note: the ICM495-60A model does not accommodate fuses.
