Mounts directly onto the contactor via the fastening method — no DIN rail needed, which saves panel space. Any mounting position is allowed, so it can be oriented to suit the enclosure layout. A 3.0 x 0.5 mm screwdriver tip is specified for the terminal screws — standard for this class of relay. ## Auxiliary contact and status signalling An integrated auxiliary switch provides a 'Tripped' message contact, giving a clear status signal back to the PLC or HMI. The contact ratings cover control voltages from 24 V (2 A) up to 400 V (1 A), with specific ratings at 120 V (3 A) and 230 V (2 A) — typical for North American and European control circuits. The thermal overload release is temperature-compensated from -40 to +60 °C, so the trip curve stays accurate across a wide ambient range — important for outdoor or unconditioned enclosures. The MTTF at high demand rate is 2,280 years, reflecting the electromechanical reliability of the design.","metaTitle":"Siemens 3RU2116-1EC0-ZW97 SIRIUS S00 Thermal Overload Relay","metaDescription":"Siemens 3RU2116-1EC0-ZW97 SIRIUS S00 thermal overload relay, Class 10 trip, 690 V rated insulation, spring-loaded terminals.
