Product details

It carries 2 instantaneous NO contacts rated at 10 A for both 24 V and 230 V AC circuits, which means it can handle typical PLC output or relay coil loads without an intermediate relay. The coil is wound for 24 V at both 50 Hz and 60 Hz, with an operating range of 0.8...1.1 × rated voltage at 50 Hz and 0.85...1.1 at 60 Hz — so it pulls in reliably even if the control transformer sags under load.

The S00 footprint — 57.5 mm high, 90 mm wide, 73 mm deep — fits alongside S00 contactors in a compact row, leaving 6 mm side clearance to adjacent devices for arc flash management. Wire terminals accept 2 × (0.5...1.5 mm²), 2 × (0.75...2.5 mm²), or 2 × 4 mm² solid or stranded conductors — enough for daisy-chaining control wiring through the auxiliary contacts.

The part has a RoHS compliance date of 10/01/2009. Lifecycle status is current production.
