Its headline rating is 52 A at 480 V in AC-3 duty — that's the motor-switching current it handles without welding the main contacts, so it's sized for a motor pulling that full-load current on a 480 V line. The coil is 24 VDC rated at 10 A holding current, and the auxiliary switch is built in — no separate add-on needed for basic feedback. Spring-type terminals on the magnet coil mean no screwdriver for the control wiring; strip, push, done.
The body is 55 mm wide, 114 mm tall, 130 mm deep — that's a standard S2 footprint, so it fits the same DIN space as any other S2 contactor. That covers most indoor panel environments, including unheated warehouses in winter.
Switching performance and mechanical life
Rated for 10 million mechanical operations typical. Switching frequency varies by duty: 1000 cycles/hour at AC-1 (resistive), 800 at AC-3 (motor start/run), 600 at AC-2 (slip-ring motors), and 250 at AC-4 (plugging/inching). That's fast enough for most sequencing but not a high-speed transfer switch. Main contact configuration is 3-pole normally open (3 NO), with one auxiliary contact (1 NO). That's the standard three-phase motor contactor layout.
