Siemens SIRIUS 3RT2015-2FB41-ZX95, contactor, AC-3, 3kW/400V, 1NO, DC 24V, with integrated diode, 3-pole, size S00, spring-loaded terminals.
The integrated diode handles the coil's flyback voltage, so you can omit an external free-wheel diode on the panel wiring.
The spring-loaded terminals accept 0.2–2.5 mm² solid or ferruled stranded wire; strip length is typically 8–10 mm. The DC 24 V coil draws about 0.2 A steady-state, so a standard 24 VDC power supply with a few hundred mA headroom per contactor is sufficient. The integrated diode means no separate snubber is needed across the coil terminals.
This part is sourced and quoted to order through independent distribution against an RFQ. Availability and current pricing are confirmed at the time of quote.
The AC-3 rating of 3 kW at 400 V means this contactor is designed for switching three-phase induction motors up to that power level during starting and running — the standard duty class for motor loads, not resistive heating.
The coil is DC 24 V and includes an integrated suppression diode, so no external flyback diode is needed across the coil terminals.
