Product details

Power dissipation per pole is 1.6 W, so in a dense panel with several relays side-by-side, account for thermal buildup — mounting position is any, but free airflow helps keep the compensation curve accurate from -40 to +60 °C.

Lifecycle status for 3RU2116-0CB1 is current production. No end-of-life notice or last-time-buy date.

Mounting is stand-alone installation or direct onto a SIRIUS S00 contactor. Screw terminals for the main circuit accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded. The auxiliary switch is integrated, so no separate module is needed for the trip signal. Dimensions are 89 mm height, 45 mm width, 80 mm depth — fits a standard DIN-rail enclosure with room for the contactor below.

Frequently asked questions

How do I get current pricing and availability for 3RU2116-0CB1?

Submit an RFQ through the storefront. Pricing and stock are confirmed at quote time; the part is sourced to order through independent distribution.

What is 3RU2116-0CB1's listed note (for message 'Tripped') on this component line?

The spec carries a note 'for message Tripped' — this means the relay has an integrated auxiliary contact that changes state when the relay trips, providing a dry-contact signal to a PLC or alarm circuit.

What is 3RU2116-0CB1's listed depth (80 mm) on this component line?

The depth is 80 mm, with a width of 45 mm and height of 89 mm. This is the body size; add clearance for wiring and airflow in the enclosure.

Will 3RU2116-0CB1 drop into a panel that was specified around 3RT6028-1AB00 without rewiring?

No — the 3RT6028-1AB00 is a contactor, not an overload relay. The 3RU2116-0CB1 is the correct overload relay to pair with that contactor, but it is a separate device that mounts directly on the contactor or adjacent on the DIN rail. If the panel was built with only the contactor, you will need to add this relay and wire the motor leads through it.
