Spring-loaded terminals on the main circuit accept 2x (0.25... 2.5 mm²) solid or stranded wire, or 2x (0.25... 1.5 mm²) finely stranded with ferrules. No screw torque to verify; strip and push. The IP20 finger-safe front terminals mean the panel cover can be open for commissioning without exposed live parts. For Type 2 coordination (contactor remains operational after a fault), use gL/gG 20 A. This is the fusing spec for the main circuit; the contactor itself has no integral overload relay — pair it with a separate SIRIUS overload (e.g., 3RU series) for motor protection.","metaTitle":"Siemens SIRIUS 3RT1316-2BF40 Power Contactor, Size S00, 4 NO","metaDescription":"Siemens SIRIUS 3RT1316-2BF40 power contactor, size S00, 4 NO main contacts, 110 VDC coil, spring-loaded terminals.
