Product details

SIRIUS S2 thermal overload relay — what it protects

The 3RU1136-1HB0: This is a SIRIUS S2-size thermal overload relay (product designation: thermal overload relay) designed to protect motors against sustained overcurrent and phase loss. It mounts directly to a Siemens contactor — the fastening method is contactor mounting, not DIN rail — so the assembly fits a compact panel footprint (width 55 mm, height 105 mm, depth 118 mm). The relay carries ATEX approval (DMT 98 ATEX G 001) for use in potentially explosive atmospheres, and the front face is IP20-rated for basic touch protection inside an enclosure.

Terminal specs and wiring reality

Both the main current circuit and the auxiliary/control circuit use screw-type terminals — no push-in or spring-cage here. Auxiliary terminals take 2x (20…16 AWG) or 2x (18…14 AWG). These are the contact ratings for the N/O or N/C auxiliary — useful for control-loop draw or PLC input sinking.

Relative humidity during operation: 100 %. Shock resistance: 8g for 10 ms. Surge voltage withstand: 6 kV. RoHS compliance is confirmed with a substance prohibition date of 07/01/2006.
