Product details

The coil is rated 24 VDC, pulling 2.3 W during closing and holding — a steady-state draw that matters for DC-supply sizing in a multi-contactor panel. The main contacts handle 10 A at 24 V (AC-12 resistive), and for motor duty at AC-4 at 400 V it's rated 6.5 A, which covers small conveyors or pump starters up to about 3 kW.

Main circuit terminals are screw-type, accepting 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded wire. That range covers common control wiring sizes; for larger feeds, the AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12.

For Type 1 coordination (contactor may need replacement), the fuse can go up to 35 A. That's the standard selectivity guidance for this frame size — useful when designing a feeder that must clear faults without upstream breaker trips.

Frequently asked questions

What is the closest functional second-source — 3RT1015-1BB42?

The 3RT1015-1BB42 is a peer in the same SIRIUS S00 frame, but it uses a 24 VAC/DC coil instead of the 24 VDC-only coil on the 1HB41. If your control voltage is pure DC, the 1HB41 is the direct fit; the 1BB42 adds AC coil compatibility but shares the same mechanical footprint and terminal layout.

What is the listed depth of 3RT1015-1HB41?

The depth is 72 mm, measured from the DIN rail mounting surface to the front of the contactor.

What wire sizes does the screw terminal accept?

The main circuit terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) solid or stranded copper. AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12.

Will 3RT1015-1HB41 drop into a panel specified around 3RT1015-1BB42 without rewiring?

Yes, the mechanical footprint, terminal layout, and DIN rail mounting are identical between the two. The only difference is the coil voltage type — the 1HB41 is 24 VDC only, while the 1BB42 accepts 24 VAC/DC. If your control circuit is pure 24 VDC, the 1HB41 is a drop-in replacement.
