Product details

It mounts directly onto a matching contactor — no separate base needed — and protects three-phase motor circuits against overload and phase-loss conditions.

Rated operational current is 4 A at the main circuit, with a maximum operating voltage of 690 V AC/DC at 50/60 Hz. The auxiliary contacts are rated 3 A at 24 V and 2 A at 230 V, and the DC-13 rating for the auxiliary is 1 A at 24 V — enough for PLC-level signal switching. The mounting position allows ±135° rotation and ±45° tilt from vertical, which gives flexibility in tight panels.

This relay is designed for contactor mounting — it clips directly onto the matching S00 contactor (e.g., 3RT2015 or similar), saving a DIN-rail slot. The main circuit connects via screw terminals at top and bottom, accepting 2× (0.5…1.5 mm²) solid/stranded or 2× (0.75…2.5 mm²) with ferrules.

Frequently asked questions

What are the key dimensions?

Depth is 78 mm, width 45 mm, height 87 mm — size S00 frame.

Will it drop into a panel specified around a 3RT1015-1BB42 contactor?

The 3RU7116-1EB0 is size S00 and designed for contactor mounting onto S00 frames. The 3RT1015-1BB42 is also size S00, so the relay clips directly onto it without rewiring the main circuit — same footprint, same terminal arrangement.

What compliance documentation is available?

The relay carries a rated impulse withstand voltage of 6 kV and insulation voltage of 690 V at pollution degree 3, which aligns with IEC 60947-4-1. The evidence does not list UL, CSA, or RoHS certs specifically, but as a standard Siemens SIRIUS catalog item, it typically ships with CE and IEC declarations. Confirm with your order documentation.
