Product details

SIRIUS 3RT1015-2BF41 — 110 VDC Coil, Spring-Loaded, Size S00

The 110 VDC coil draws 3.3 W during both closing and holding. Pick-up voltage is 0.85 × rated; drop-out is 1.1 × rated.

Termination and Mounting

Both main and control circuits use spring-loaded terminals, accepting 2x (0.25 … 2.5 mm²) solid or stranded — no screw torque to verify, no loosening under vibration.

Switching Ratings and Duty

Rated operational current at AC-12 (resistive) is 10 A maximum. For motor loads: AC-2 at 400 V delivers 3 kW; AC-4 at 400 V delivers 6.5 A. DC switching is specified per voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. Mechanical endurance is 30 million cycles — a long-life figure for a size S00 frame, suitable for high-cycle conveyor or pump applications where the contactor operates frequently.

Type 2 coordination (contactor remains usable after clearing the fault) requires a 20 A gL/gG fuse.

Frequently asked questions

What is the depth of 3RT1015-2BF41?

The depth is 73 mm, measured from the DIN-rail mounting surface to the front of the contactor.

Will 3RT1015-2BF41 drop into a panel specified around 3RT1015-1BB42 without rewiring?

Yes, if the control voltage is 110 VDC. Both share the same S00 frame, 45 mm width, spring-loaded terminals, and DIN-rail mounting. The only difference is the coil voltage — verify your control supply before swapping.
