Product details

Integrator's read on the 3RT2036-3SF30

MTBF sits at 52 a, which for a contactor in continuous duty is a solid reliability figure — not a consumable part you plan to swap on a PM schedule.

That helps when the gland plate forces an odd orientation. Dimensions: 55 mm wide, 114 mm high, 130 mm deep. Clearances: 10 mm upward/downward/forward, 6 mm at the sides. The S2 frame is a standard footprint; it'll slot into a multi-contactor bank without surprises.

Switching duty and coil draw

Rated for AC-1 (resistive) at 1 000 ops/h, AC-3 (motor starting) at 800 ops/h, and AC-4 (plugging/inching) at 250 ops/h. Coil inrush peaks at 25 A, steady-state draw is 2 VA at 50 Hz or 60 Hz. Auxiliary switch is included — no add-on block needed for basic status feedback.

Frequently asked questions

Where can I buy 3RT2036-3SF30 and get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm number.

What is the MTBF of the 3RT2036-3SF30?

The listed MTBF is 52 a. That's a reliability figure for continuous duty — not a part you'd schedule for routine replacement.

Will 3RT2036-3SF30 drop into a panel specified around 3RT2015-1BW42?

Both are SIRIUS contactors, but the 3RT2036-3SF30 is an S2 frame while the 3RT2015-1BW42 is a smaller S0 frame. The S2 is wider (55 mm vs S0's typical 45 mm) and deeper. It won't drop into the same DIN footprint without panel rework — check the available rail space and enclosure depth before swapping.
