Product details

The 24 V DC coil draws 3.3 W holding power, with a pick-up threshold of 0.85 x rated voltage and a drop-out of 0.1 x rated voltage — meaning it holds in reliably down to about 20.4 V and drops out cleanly below 2.4 V, a useful margin for brownout ride-through on a 24 VDC control bus.

Side-by-side mounting is permitted with 6 mm spacing to adjacent devices for heat dissipation. The spring-loaded terminals on the main current circuit accept 2x (0.25... 2.5 mm²) solid or stranded conductors (2x 24...14 AWG), so no ferrule crimping is required for stranded wire — a time-saver during panel build.

Rated operational currents and coordination

Rated for AC-12 resistive loads at 10 A maximum, and AC-2 motor duty at 3 kW / 400 V. For short-circuit protection, type 2 coordination requires a gL/gG fuse rated 20 A; type 1 coordination allows up to 35 A. The auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V DC, covering both PLC-level signal switching and higher-voltage interlock circuits.

Frequently asked questions

Will 3RT1015-2BB42-ZX95 drop into a panel that was specified around 3RT1015-1BB42 without rewiring?

Yes, the 3RT1015-2BB42-ZX95 shares the same S00 footprint (45 mm width, 73 mm depth) and DIN rail mounting as the 3RT1015-1BB42, so it fits the same panel layout. The key difference is the spring-loaded terminals on the main circuit versus screw terminals — no re-drilling needed, but verify the conductor preparation matches the spring-cage requirements (0.25...2.5 mm² solid or stranded, no ferrule required).

Where can I buy 3RT1015-2BB42-ZX95?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing; the quote will confirm lead time and quantity options at that point.

What compliance documentation does Siemens provide for 3RT1015-2BB42-ZX95?

The reference code per DIN EN 81346-2 is Q (power switching device). The part carries IP20 finger-safe protection on the front and terminals, and is rated for pollution degree 3. Standard Siemens documentation includes the declaration of conformity for low-voltage directive compliance, though specific RoHS/REACH declarations should be requested at quote time.
