Pumps, irrigation controllers and farm equipment at the end of long overhead services take a beating from utility and lightning-induced surges. The Intermatic AG2401C3 is a Type 1 or Type 2 surge protective device for 120/240 VAC single-phase, 3-wire services, rated 50 kA SCCR with a 20 kA nominal discharge current. It mounts through a 7/8 in knockout on a meter base or panel and comes in clamshell packaging. Why electricians pick it Type 1 or Type 2 rated: line side of the service or load side on a breaker. Thermally protected MOV (TPMOV) design is built to avoid the hazardous failure modes of standard MOVs. Green LED shows protection is active at a glance. Weatherproof, UV-resistant polycarbonate housing rated NEMA 1/2/4/4X for indoor or outdoor use. Colour-coded 18 in, 12 AWG leads and a 1/2 in threaded nipple.
