Product details

It is built on the S00 contactor frame (45 mm wide, 57.5 mm tall, 111 mm deep) and mounts via screw or snap-on onto a DIN rail.

The six NO contacts are rated for switching at multiple voltage levels: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The 6 kV rated surge voltage resistance means the contactor can handle transient overvoltages common in industrial power distribution without flashover. The DC coil draws 3.2 W closing and holding — a steady-state load that matters for power-supply budgeting in a 24 VDC control loop.

The contactor accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² per terminal. Shock resistance is 10g for 5 ms and 5g for 10 ms, so it holds up in applications with moderate vibration, such as near conveyor drives or compressors.

Frequently asked questions

What is the closest functional second-source to 3RH1262-1BB40?

The 3RH2362-2AF00 is a functional peer within the same SIRIUS family, but verify contact configuration and coil voltage against your BOM before substituting; the 3RH1262-1BB40 has six NO contacts at 24 VDC.

What compliance documentation does Siemens provide for 3RH1262-1BB40?

The part carries a substance prohibition date of 01.07.2006, indicating RoHS compliance per EU Directive 2002/95/EC. The reference code per IEC 81346-2 is K (contactor/relay).

Where can I buy 3RH1262-1BB40 and how is it quoted?
