The Size S00 form factor (89 mm high, 45 mm wide, 80 mm deep) is the smallest in the SIRIUS overload relay family, designed for direct mounting to S00 contactors or stand-alone installation on a DIN rail. The screw-type terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire, and the M3 main-contact screws are compatible with a Pozidriv PZ2 bit — a common panel-building tool. ## Deployment context and environmental limits This relay is temperature-compensated from -40 to +60 °C, so the trip curve stays consistent whether the panel is in a cold warehouse or a warm motor control center. The integrated auxiliary switch provides a normally-closed and normally-open contact for remote trip indication. The relay's note — \"for message 'Tripped'\" — confirms that the auxiliary contacts are wired to signal a tripped state, not just a contactor status. This is the contact you'd run back to a PLC digital input or a status light on the panel door.","metaTitle":"Siemens 3RU2116-0AB1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2116-0AB1 SIRIUS thermal overload relay, Class 10 trip, Size S00, 690 V rated.
