The Honeywell R4234B 1054 Magnetic Contactor is a 3-pole, single-throw device designed to switch heavy loads. It is rated for 60 amps and uses a 120-volt coil. The 3-pole construction allows three-phase loads such as motors and compressors to be controlled from a single control line, making it suitable for HVAC equipment and other industrial panels. The R4234B 1054 variant uses magnetic actuation to deliver fast, reliable switching for frequent cycling.
