HC4-H-AC100V Panasonic HC4 Relay – 4 Form C, 5 A, 100/110 V AC Coil
The Panasonic HC4-H-AC100V (Panasonic part number AP3144K) is a plug-in control relay from the HC series, which Panasonic designed for control panels switching from 1 A to 10 A. This version has four changeover contacts (4 Form C), a dust-cover construction and an AC coil. The coil is rated for both 100 V AC and 110 V AC, so this is the part to order when a panel calls for an HC4 relay at 110 V AC (sometimes searched as HC4-H-AC110V). Panasonic has now discontinued the HC series, and the HC4-H-AC100V is supplied as a like-for-like replacement for machines and panels already in service.
Replacement for Installed Equipment
HC relays were widely used in factory automation equipment, control panels, power supply equipment, molding machines, machine tools and welding equipment. Replacing a worn relay with the same HC4-H-AC100V keeps the original socket, wiring and panel documentation unchanged. Matching sockets and terminal sockets were available for the HC series.
