Product details

Motor protection relay for the S00 contactor frame

The 3RU6116-0EB1 is a SIRIUS thermal overload relay sized for the S00 contactor frame. It protects a three-phase motor by monitoring current through the main circuit and tripping via a bimetallic thermal element when overload persists.

Mounting and wiring: stand-alone or direct to contactor

The relay supports stand-alone installation in any mounting position. Dimensions are 45 mm wide, 89 mm high, and 80 mm deep — it occupies a single modular DIN-space width. Side clearance to grounded parts must be at least 6 mm. Main circuit and auxiliary circuit connections use screw-type terminals. Auxiliary terminals accept 2× (20…16) or 2× (18…14) AWG. Tightening torque for main contacts is 0.8 to 1.2 N·m.

Environmental limits and compliance documentation

Shock resistance is 8 g for 11 ms per IEC 60068-2-27. Maximum installation altitude is 2,000 m above sea level. Substance prohibitance per RoHS applies from May 1, 2012. Insulation voltage is 690 V at pollution degree 3.

Frequently asked questions

What compliance documentation is available for the 3RU6116-0EB1?

The relay complies with RoHS substance prohibitance effective May 1, 2012. It is designed to IEC standards for thermal overload relays, with insulation voltage rated at 690 V at pollution degree 3.
