Product details

It carries a 52 V DC coil and provides 2 normally open instantaneous contacts. Rated operational current is 10 A at 24 V, derating to 6 A at 230 V and 1 A at 690 V. Pollution degree 3 applies per the datasheet.

Depth is 72 mm, which is the dimension to account for when spacing against the gland plate or adjacent devices. Terminal capacity accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12.

Shock resistance is rated at 10g for 5 ms and 5g for 10 ms.

Frequently asked questions

What is the depth of 3RH1122-1BK80?

The depth is 72 mm, which is the dimension from the mounting surface to the furthest point of the contactor body. This is the critical dimension for panel depth clearance.

What wire sizes does 3RH1122-1BK80 accept?

The terminals accept solid conductors in the following combinations: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12.

What compliance documentation is available for 3RH1122-1BK80?

The part is RoHS compliant per the 2006/07/01 substance prohibition date. The manufacturer provides a CE declaration of conformity and the part is designed to IEC/EN 60947-5-1 standards for control circuit devices.
