It mounts directly onto a S2 contactor — no separate DIN-rail bracket needed — and the 118 mm depth, 55 mm width, 105 mm height footprint keeps the panel layout tight. The screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid or stranded, or 2x (0.75...2.5 mm²) with ferrules. The 65 A rated operational current is the continuous motor FLA this relay can carry and protect — match it to the motor nameplate, not the contactor rating. Power dissipation runs 17.1 W total typical at rated current — account for that heat inside the enclosure, especially when ganged with the contactor. Fastening method is contactor mounting — the relay clips directly onto a SIRIUS S2 contactor, no DIN rail required. Mounting position allows vertical surface with ±135° rotation or ±45° tilt forward/back. Required side spacing to grounded parts is 6 mm.","metaTitle":"Siemens 3RU7136-4JB0 SIRIUS Thermal Overload Relay, 65 A, Cl","metaDescription":"Siemens 3RU7136-4JB0 SIRIUS thermal overload relay, 65 A rated current, Class 10 trip, 690 V, S2 size.
