Product details

Trip class and motor protection timing

The 3RU2116-0JB1: The thermal overload release design (bimetal + heater) provides inverse-time protection that tracks the motor's actual heating profile, not a fixed threshold.

Panel footprint and mounting

Size S00 frame — 45 mm wide, 89 mm tall, 80 mm deep — fits the standard SIRIUS S00 mounting footprint used across contactors and relays in this series.

Auxiliary contact ratings across control voltages

The note "for message 'Tripped'" indicates this auxiliary contact is wired specifically to signal the tripped state back to the PLC or annunciator, not the reset or test position.

Environmental range and temperature compensation

Operating ambient -40…+70 °C with temperature compensation active over -40…+60 °C — the compensation circuit corrects the trip point for ambient changes so the motor protection stays accurate regardless of panel heat or outdoor installation. Storage and transport range -55…+80 °C — wide enough for unheated warehouses or container shipping across climate zones.

Frequently asked questions

Will 3RU2116-0JB1 drop into a panel specified around 6ED1052-1MD08-0BA1 without rewiring?

No — 6ED1052-1MD08-0BA1 is a LOGO! logic module, not an overload relay. The 3RU2116-0JB1 is a thermal overload relay with a completely different form factor, wiring scheme, and function. Panel rewiring and a different mounting footprint would be required.
