Product details

Front IP20, ATEX DMT 98 G 001 certified for explosive atmospheres. 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.

Frequently asked questions

Where can I buy 3RU1136-4HB1?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What is the depth of 3RU1136-4HB1?

118 mm depth, with 55 mm width and 105 mm height.

What compliance documentation does 3RU1136-4HB1 carry?

ATEX DMT 98 ATEX G 001 for explosive atmospheres, IP20 front protection, substance prohibitance date 07/01/2006 (RoHS/REACH compliance indicator). Reference code per IEC 81346-2: F.

Will 3RU1136-4HB1 drop into a panel specified for 3RU2116-1FC1?

Both are SIRIUS Size S2 overload relays with the same mounting footprint and screw terminals. The 3RU1136-4HB1 is a direct functional match for the same contactor frame — no rewiring needed if the panel was laid out for a Size S2 relay.
