This relay mounts directly onto a Siemens S2-size contactor via the contactor mounting fastening method — no separate DIN-rail footprint needed. The vertical mounting surface allows ±135° rotation and ±45° tilt front-to-back, which gives panel builders flexibility in tight enclosures. Side spacing to grounded parts requires 6 mm minimum clearance. ## Electrical ratings and connections Rated operational current is 16 A at 690 V, 50-60 Hz, with a rated insulation voltage of 690 V (pollution degree 3) and surge voltage resistance of 6 kV. Main circuit terminals are screw-type, top and bottom, accepting 2×(0.5-1.5 mm²) solid/stranded or 2×(0.75-2.5 mm²) finely stranded with ferrule. Torque spec is 3-5 N·m. Auxiliary and control circuits also use screw terminals, accepting 2×(20-16 AWG) or 2×(18-14 AWG). Short-circuit protection for the auxiliary switch requires a gL/gG 6 A fuse or quick 10 A fuse. ## Power dissipation and thermal management Per-pole dissipation is 3.5 W. This thermal load must be considered when grouping multiple relays in a confined panel — the 6 mm side spacing requirement helps manage heat buildup.","metaTitle":"Siemens 3RU5136-4AB0 SIRIUS Thermal Overload Relay, 11-16 A,","metaDescription":"Siemens 3RU5136-4AB0 SIRIUS thermal overload relay, 11-16 A adjustable, Class 10 trip, 690 V rated.
