It carries a 20-33 V coil and a 1 NO + 1 NC auxiliary switch block. The contactor is rated for AC-3 switching at up to 800 operations per hour and AC-4 at 250 ops/hr, with a mechanical life of 10 million cycles typical.
Dimensions are 114 mm high, 55 mm wide, 130 mm deep. Clearance requirements: 10 mm upward, downward, and forward; 6 mm at the sides. Coil inrush peaks at 3 A; steady-state draw is 2 VA at both 50 and 60 Hz.
This contactor is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for volume pricing.
It is a Size S2 power contactor with a 20-33 V coil, spring-type terminals, 1 NO + 1 NC auxiliary contacts, AC-3 switching rate up to 800 ops/hr, AC-4 at 250 ops/hr, and mechanical life of 10 million cycles typical.
As a Siemens SIRIUS product, it carries the standard CE, UL, CSA, and IEC certifications typical for the series. Specific RoHS and REACH declarations are available from the manufacturer upon request.
The 3RT2036 is a Size S2 frame (114x55x130 mm) while the 3RT2015 is a smaller Size S0 frame — physical dimensions differ, so it will not drop into the same DIN footprint without panel rework. Wiring and terminal styles may also differ.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
