Product details

Ratings & So-What

The magnet coil is screw-type terminals rated 20–33 V, with a pickup inrush peak of 12 A. At 24 V rated value the auxiliary contact carries 10 A; at 48 V it drops to 2 A, and at 125 V to 0.9 A — so if you are switching a 48 VDC pilot light or a 125 VDC relay, the contact rating governs the load, not the coil voltage.

Wiring & Termination

Terminals accept solid or stranded conductors: 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²). The auxiliary switch is present, so you get one N.O. + one N.C. built in — no separate block needed for basic feedback.
