The front face carries IP20 protection — finger-safe for panel installation — and the relay carries ATEX certification (DMT 98 ATEX G 001), confirming suitability for use in potentially explosive atmospheres when paired with an appropriate motor circuit breaker upstream. The mounting position is flexible: can be installed on a vertical surface with ±135° rotation or ±45° tilt front-to-back, which helps when fitting into tight cabinet layouts. No extra breathing space needed above or below the relay, so it stacks cleanly against adjacent devices. Solid conductor capacity: 2× (0.5…1.5 mm²) and 2× (0.75…2.5 mm²); stranded accepts 2× (0.75…25 mm²) or single 0.75…35 mm². AWG equivalents for auxiliary contacts: 2× (20…16) and 2× (18…14). Finely stranded with core-end processing follows the same ranges as solid — no special ferrule required for the control wiring. ## Environmental and electrical ratings — the so-what Operates across -20…+70 °C ambient, stores and transports at -55…+80 °C. Relative humidity tolerance is 100 % during operation — condensing environments are acceptable as long as the IP20 front is respected. Shock resistance rated at 8g for 10 ms, which covers most industrial vibration profiles on pumps, conveyors, and compressors. Auxiliary contact ratings: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V. These are the switching capacities for the signal contacts that feed the PLC or control relay — important when sizing the control transformer and verifying the PLC input card can sink the current. Each pole dissipates 4.6 W under load — total 13.8 W for the three poles. That heat must be considered in the enclosure thermal budget, especially when multiple overloads are ganged in a compact panel. The 3RU1136-4EB0 carries a lifecycle status of current — Siemens has not flagged it for phase-out or discontinuation. It remains a standard catalog item in the SIRIUS portfolio, so supply through independent distribution is steady. No official successor order code has been issued.","metaTitle":"Siemens 3RU1136-4EB0 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1136-4EB0 SIRIUS thermal overload relay, CLASS 10, 3-pole, S2 size, IP20 front, ATEX, screw terminals.
