Product details

The coil is rated 220-240 V AC and terminates on screw-type terminals, which is the standard for panel builders who prefer field-replaceable terminations over cage-clamp on larger frames. It mounts via screw fixing with a vertical mounting surface that can be rotated ±90° or tilted ±22.5° forward/backward, giving the panel builder flexibility to fit tight enclosures without custom brackets.

Clearances and wiring

The contactor occupies 120 mm width, 172 mm height, and 170 mm depth. That 20 mm forward clearance is the critical dimension for gland-plate planning — if you're stacking contactors in a row, the forward gap governs the door swing. Power circuit wiring accepts stranded cable 25-120 mm². The auxiliary/solid range is 2× (0.5-1.5 mm²), 2× (0.75-2.5 mm²), max 2× (0.75-4 mm²). The 120 mm² stranded capacity means this contactor can handle the main feeder for a moderate motor control center without a separate terminal block.

Duty cycles and endurance

Switching frequency varies by duty: AC-1 (resistive) max 800 operations/hour, AC-3 (motor start/run) max 750 ops/h, AC-4 (plugging/inching) max 130 ops/h. The AC-3e rating also maxes at 750 ops/h. For a conveyor line cycling once per minute, that's well within the 750 ops/h ceiling — no derating needed. Mechanical endurance is 10 million cycles typical, so the contactor outlasts most panel refreshes. Operating delay is 40-60 ms on both AC and DC pick-up. Arcing time is 10-15 ms. These numbers matter for selectivity coordination: the arcing time is short enough that a downstream MCB can clear a fault before the contactor's arc extinguishes, preventing weld risk.

The auxiliary switch is included, rated at 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. That covers most PLC input card ranges without an interposing relay.

Frequently asked questions

How do I get current pricing and availability for 3RT1056-6AP36-ZX95?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time — we source across independent distribution channels and can provide a firm date before you commit the BOM line.

What is 3RT1056-6AP36-ZX95's listed depth?

The depth is 170 mm. Combined with 120 mm width and 172 mm height, it fits standard 200 mm deep enclosures with room for the 20 mm forward clearance.

What wire sizes does the 3RT1056-6AP36-ZX95 accept?

Power circuit stranded cable: 25-120 mm². Auxiliary/solid connections: 2× (0.5-1.5 mm²), 2× (0.75-2.5 mm²), max 2× (0.75-4 mm²). The coil terminals are screw-type.

Will 3RT1056-6AP36-ZX95 drop into a panel specified around 3RT1055-6QF35 without rewiring?

Not without checking the mounting footprint and power terminal spacing. The 3RT1056 is Size S6; the 3RT1055 is a smaller frame (Size S3 or S4 depending on variant). The 120 mm width and 170 mm depth of the S6 will not fit the same DIN-rail or screw-hole pattern as the S3/S4. You would need to re-drill the mounting plate and possibly extend the power cables.
