Product details

Its main contact ratings — 96 A at 480 V and 99 A at 600 V — mean it can handle high-current three-phase motors up to roughly 55 kW at 480 V, typical for pumps, compressors, and conveyors in heavy-duty applications. The contactor includes an integrated auxiliary switch, saving a separate aux block on the DIN rail.

Coil and switching performance

The 110 VDC coil has a pick-up threshold of 0.7 times rated value (77 V) and an arcing time of 10–15 ms, with a DC dropout delay of 80–90 ms. That relatively long dropout is useful for ride-through on brief voltage sags but means the contactor will not drop out instantly on a control-power glitch — something to account for in safety-circuit timing. Switching frequency is rated at 600 operations per hour for AC-1 resistive loads and 400 ops/h for DC-1 loads, so it is not a high-speed chopper but is fine for typical motor start/stop cycles.

The contactor measures 172 mm high, 120 mm wide, and 170 mm deep — a substantial footprint that needs generous enclosure space and clearance. Terminals accept solid or stranded wire: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²). The screw-fixing method uses a single 9 mm hole for mounting.

Frequently asked questions

Where can I buy 3RT1456-6XF46-0LA2 and get a price?

This contactor is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 3RT1456-6XF46-0LA2?

The closest peer in the SIRIUS family is the 3RT1055-6QF35, but it is a smaller frame size (S2 vs S6) with lower current ratings — it will not drop into a panel wired for the S6 without rewiring and a different mounting hole pattern.

What is the depth of 3RT1456-6XF46-0LA2?

The depth is 170 mm, with a forward clearance requirement of 20 mm for arc flash and heat dissipation.

What wire sizes does 3RT1456-6XF46-0LA2 accept?

It accepts solid or stranded wire: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²).
