Product details

SIRIUS 3RU1116-1DC1 thermal overload relay

Cage clamp terminals on the main circuit accept 2x (0.5... 2.5 mm²) solid or 2x (0.5... 1.5 mm²) finely stranded with ferrule — a clean, vibration-resistant connection for panel wiring.

Mounting position is flexible: the relay can be installed on a vertical surface with ±135° rotation and ±45° tilt front-to-back. Stand-alone installation means it does not require a separate contactor base — it clips directly onto the mounting rail or panel. The 78 mm depth and 92 mm height fit standard S00 form factor enclosures. Side clearance of 6 mm is needed for ventilation and wiring access.

The relay withstands 100 % relative humidity during operation and shock up to 8g for 10 ms. It carries ATEX protection type DMT 98 ATEX G 001, suitable for use in potentially explosive atmospheres when installed per the relevant directive.

Frequently asked questions

Where can I buy 3RU1116-1DC1 and what is the lead time?

The 3RU1116-1DC1 is sourced to order through our independent distribution network. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price.

What is the closest functional second-source to 3RU1116-1DC1?

The 3RU2116-1FC1 is a peer SIRIUS thermal overload relay in the same S00 frame size, but it belongs to a different rating range and may have different trip current settings. Verify the motor FLA and coordination requirements before substituting — the 3RU1116-1DC1 is the correct part for the original BOM line.

What is the depth of the 3RU1116-1DC1?

The 3RU1116-1DC1 has a depth of 78 mm, a width of 45 mm, and a height of 92 mm, fitting the standard S00 form factor.

What wire sizes does the 3RU1116-1DC1 accept?

The cage clamp terminals accept 2x (0.5... 2.5 mm²) solid conductors or 2x (0.5... 1.5 mm²) finely stranded with core end processing (ferrule). AWG equivalents are 2x (24... 14) for the main contacts.
