Product details

Its 45 mm width and 70 mm height fit standard DIN-rail enclosures; depth is 73 mm including coil terminals. Mounting is screw or snap-on onto 35 mm rail per DIN EN 60715, with ±180° rotation on a vertical surface and ±22.5° tilt forward/backward — useful when panel layout is tight. Strip length and ferrule sizing follow standard practice for cage-clamp style; no screw torque to verify.

Duty ratings and switching life

Coil is 24 VDC rated; the contactor holds in at nominal and drops out below the release threshold typical for this class. Main contact ratings vary by load type: at AC-1 (resistive) the maximum switching rate is 1,000 cycles per hour; at AC-3 (motor starting) it is 750 cycles per hour; at AC-4 (inching/plugging) it drops to 250 cycles per hour. The AC-3e rating also sits at 750 cycles per hour. Switching capacity for DC loads: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V. At 400 V AC the rated operational current is 3 A. DC operating time is 7 to 13 ms.

This order code carries a current lifecycle stage. No official successor has been issued — this remains the active variant for new BOM lines and MRO spares.

Frequently asked questions

Where can I buy 3RT2017-2BM42-ZW97?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 3RT2017-2BM42-ZW97?

The closest peer in the same SIRIUS family is 3RT2015-1BW42, which shares the Size S00 footprint and spring-terminal design but differs in coil voltage and some switching ratings — verify coil compatibility before substituting.
