Product details

Rated for 10 A at both 24 V and 230 V, it handles pilot-duty and signal-level loads across a wide voltage range — 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 3 A at 400 V, 2 A at 500 V, 1 A at 690 V, and lower currents at 440 V (0.5 A) and 600 V (0.26 A) — so the same block works in 24 VDC control circuits and 230 VAC motor starter feedback loops without derating surprises.

Mounting and integration details

The S00 footprint — 45 mm wide, 58 mm high, 73 mm deep — fits alongside S00 contactors in a compact row, with clearance requirements of 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side for heat dissipation and wiring access.

Terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded wire, plus AWG equivalents 2x (20 to 16), 2x (18 to 14), and 2x 12. Screw-type clamping, so strip length and torque matter — the 4 mm² capacity means you can loop through for daisy-chained commons without a separate terminal block.

RoHS compliance date of October 1, 2009, covering substance restrictions.

Frequently asked questions

What are the key switching ratings for this auxiliary contactor block?
