Product details

It is a current-production part. The 110 V DC coil (rated value 110 V) with spring-type terminals means this contactor is wired without screw terminals — strip the wire, push it in, done. It accepts solid or stranded conductors from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) for looping through. Mounting is via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with flexible positioning: +/-180° rotation on a vertical surface, and tilt forward/backward by +/-22.5° on a vertical surface.

The DC coil draws 6 A at 24 V, 2 A at 48 V or 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V — these are the inrush/hold currents the control transformer or DC supply must deliver. The coil operating range has an initial value factor of 0.8 and full-scale value of 1.1, meaning it picks up reliably at 88 V (80% of 110 V) and holds through 121 V. Switching frequency depends on duty: 1 000 operations/hour at AC-1 (resistive loads), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The AC-3e rating also caps at 750/h. For a conveyor running 8 hours at 30 cycles/hour, that's 240 ops — well within limits. DC switching time is 7 to 13 ms. The main contacts are rated for 20 to 12 A. Mechanical endurance is 10 000 000 operations typical — the contactor itself will outlast most applications before the contacts wear. No auxiliary switch is fitted (Auxiliary Switch: No), so plan for an external aux block if feedback is needed.

Environmental and Integration Constraints

Dimensions: 45 mm wide, 70 mm high, 121 mm deep. The HP rating at 230 V is 0.75 hp — useful for small single-phase motor loads in North American panels, though the primary application is three-phase at 400 V.

Frequently asked questions

How do I get current pricing and availability for 3RT2015-2BF48-3MA5?

Submit an RFQ through this listing. Pricing and availability are confirmed at quote time; we source this current-production part to order.

What wire sizes does the spring terminal accept?

Solid or stranded conductors from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) for looping through.

Will 3RT2015-2BF48-3MA5 drop into a panel specified around 3RT2015-2BB44-3MA0?

Both are Size S00 contactors with the same 45 mm width, 70 mm height, and 121 mm depth footprint, and both mount on 35 mm DIN rail. The main difference is the coil voltage: this one is 110 V DC; the 3RT2015-2BB44-3MA0 uses a different coil voltage. Check the coil rating before substitution — the mechanical fit is identical.
