Product details

The Siemens 3RU1116-0GB0 is a SIRIUS thermal overload relay in size S00, designed for contactor mounting and motor protection up to 690 V AC-3.

Mounts directly onto a contactor — no DIN rail required. The 45 mm width and 87 mm height fit the S00 footprint, with zero clearance needed upwards, forwards, backwards, or downwards. Side clearance of 6 mm is sufficient. The mounting position allows ±135° rotation and ±45° tilt front/back from vertical, giving panel builders flexibility in tight enclosures.

Accepts solid conductors 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), or finely stranded with ferrule. AWG equivalents: 2x (20…16), 2x (18…14), 2x 12. The 78 mm depth leaves enough finger space behind the panel for wiring access.

Environmental and electrical ratings

Withstands 8g / 10 ms shock. Thermal dissipation at AC hot state is 4.8 W total, 1.6 W per pole. Surge voltage resistance rated at 6 kV. Relative humidity tolerance up to 100 %.

Frequently asked questions

What is the trip class of 3RU1116-0GB0?

Class 10, meaning it will trip within 10 seconds at 7.2× the current setting — suitable for standard motor starting profiles.

What is the depth of 3RU1116-0GB0?

78 mm. This is the dimension behind the panel face when mounted on a contactor.

What conductor sizes does the 3RU1116-0GB0 accept?

Solid conductors: 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²). Finely stranded with ferrule: same ranges. AWG equivalents: 2x (20…16), 2x (18…14), 2x 12.

Where can I buy 3RU1116-0GB0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
