Product details

The 3RH2271-1BB40: Depth is 117 mm, which includes clearance for the coil terminals and wiring. Side clearance of 6 mm and vertical clearances of 10 mm (up, down, forward) keep heat dissipation and arc quenching zones clear.

Coil and contact ratings

Rated control supply voltage is 24 VDC, with a pick-up threshold of 0.8 × rated (19.2 V) and a drop-out threshold of 0.55 × rated (13.2 V). Coil holding power is 4 W DC, and closing power is also 4 W DC — the magnet circuit is fully saturated at pick-up, so inrush is minimal.

Full manufacturer traceability and warranty apply.
