This 55 mm DC-frame block mounts directly to Eaton's D-frame XTCE contactors (approximately 50–72 A), snapping together with the contactor to form a compact, fully wired starter without extra panel space or jumper wiring. Ambient-compensated bimetal strips and built-in phase-loss sensitivity trip the control circuit before a stalled, overloaded, or single-phasing motor is damaged.\u003c\/p\u003e\n\u003cp\u003eEach unit has an adjustable trip-current dial so you can match protection precisely to the motor's full-load amps within its range.
