Mounting is standalone with flexibility: vertical surface, ±135° rotatable, ±45° tiltable front/back. The Size S2 frame mates with Siemens S2 contactors (3RT2 series). Standalone installation, not DIN-rail snap-on; plan for panel-mount with the 55×105 mm footprint and 118 mm depth. The 5.2 W per pole heat dissipation adds up to 15.6 W total — account for that in enclosure thermal calculations. Standalone installation with screw terminals. Wire ranges: main circuit accepts stranded 2×(0.75…25 mm²) or single 0.75…35 mm²; auxiliary contacts take solid 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²), also finely stranded with core-end processing. AWG equivalents for aux: 2×(20…16) and 2×(18…14). Shock rated 8g/10 ms. Storage and transport -55…+80 °C, operating -20…+70 °C, 100 % RH during operation.","metaTitle":"Siemens 3RU1136-4HB1 SIRIUS Thermal Overload Relay, Size S2,","metaDescription":"Siemens 3RU1136-4HB1 SIRIUS thermal overload relay, Size S2, Trip Class 10, 3-pole, IP20 front, ATEX approved.
