Product details

Rated for contactor mounting directly onto a matching S00 contactor, saving panel space and wiring compared to a separate base-mount relay.

Terminal specs and wiring

Main circuit terminals accept solid conductors: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²); AWG equivalents: 2x (20...16), 2x (18...14), and 2x 12. Auxiliary/control circuit terminals also accept 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²) solid, with AWG 2x (20...16) and 2x (18...14). Finely stranded conductors with ferrule: same ranges as solid — 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²).

Operating temperature range -20 to +70 °C; storage and transport -55 to +80 °C. Rated for 100 % relative humidity during operation. Shock resistance 8g / 10 ms; surge voltage withstand 6 kV. ATEX certification (DMT 98 ATEX G 001) for use in potentially explosive atmospheres. RoHS substance prohibition date 01.07.2006.

Frequently asked questions

What is the depth of 3RU1116-0FB0?

78 mm.

What solid conductor sizes does 3RU1116-0FB0 accept?

Main and auxiliary terminals accept 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²) solid, with AWG equivalents 2x (20...16), 2x (18...14), and 2x 12 for main.

Does 3RU1116-0FB0 drop into a panel specified for 3RT1023-1AL20 without rewiring?

The 3RU1116-0FB0 is a Size S00 thermal overload relay designed for contactor mounting onto a matching S00 contactor. The 3RT1023-1AL20 is a different device class (contactor or starter), so direct drop-in without rewiring is not guaranteed — verify the contactor frame size and terminal layout against your panel design.
