Product details

The coil pulls in on 24 VDC with a closing power of 4 W, and the integrated varistor suppresses the inductive kick — no external snubber needed across the coil terminals.

Switching capacity and contact ratings

The contacts are rated for the full range of control voltages you'd expect in a panel: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. At 60 V the rating drops to 4.7 A; at 220 V it's 1.2 A. The arcing time sits between 10 and 15 ms, and the mechanical life is a typical 10 million operations. That's a contact block built for high-cycle applications like conveyor interlocking or valve sequencing.

The size S00 footprint — 45 mm wide, 57.5 mm tall, 121 mm deep — fits the compact slot in a motor starter combination or control panel.

Relative humidity minimum 10 %. RoHS compliance date of July 1, 2006 is on record. The varistor surge suppressor is built into the design, so the part meets the usual CE and UL requirements for auxiliary contactors in this class.
