Product details

It carries 2 normally-open and 2 normally-closed auxiliary contacts, rated for AC switching across a range of voltages: 6 A at 24 V, 3 A at 110 V, 1.2 A at 220 V, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V. That spread means it handles everything from low-voltage PLC pilot duty up to 400 V control transformer secondaries without derating surprises.

The 45 mm width and 73 mm depth mean it fits a standard 45 mm-wide slot in a panel layout; the 57.5 mm height leaves room for wiring ducts above and below.

Coil and contact reliability

The AC coil draws 37 VA pick-up, 5.7 VA holding — typical for a size S00 relay, so the control transformer sizing is straightforward. That matters when the relay is feeding a digital input card: you want the contact to wet a low-energy circuit reliably, not bounce or oxidize.
