Product details

Part identity and mounting

The 45 mm width and 73 mm depth fit standard panel layouts; clearance requirements are 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side.

The auxiliary contact is rated 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, and 3 A at 400 V. Switching frequency varies by duty: up to 1 000 operations per hour in AC-1 (resistive loads), 750/h in AC-2 and AC-3 (motor starting/running), and 250/h in AC-4 (plugging/inching). For a conveyor motor running AC-3, that 750/h ceiling is well above typical cycle rates. Arcing time is 10 to 15 ms at AC, and the contactor is rated for 30 000 000 typical mechanical operations — so it's built for high-cycle applications like packaging machines or material handling. Wire range accepts solid or stranded 0.5 to 4 mm² (single wire) and 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm² for paralleled conductors. That covers most control-circuit wiring gauges without needing adapters.

The wide storage range means it can sit in a spare-parts bin in an unconditioned warehouse without issue.

Frequently asked questions

What is the closest functional second-source for this contactor?

The 3RT2017-1AB01-ZX95 is a Size S00 peer from the same SIRIUS family. The main difference is the coil voltage and auxiliary configuration — verify your control voltage and auxiliary contact count before substituting. The 3RT2016-1AP01-ZX95 and 3RT2017-2AP01-ZW96 are also Size S00 variants with different coil/auxiliary specs.

What are the key mounting dimensions?

The contactor is 45 mm wide, 58 mm high, and 73 mm deep. It snaps onto a 35 mm DIN rail (DIN EN 60715) and requires 10 mm clearance upwards, forwards, and downwards, plus 6 mm at the side.

What wire sizes does the screw terminal accept?

Solid or stranded wire from 0.5 to 4 mm² for single conductors, and 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm² for paralleled conductors.

Can this contactor replace a 3RT2017-1AB01-ZX95 in an existing panel?

Both are Size S00 with the same 45 mm width and DIN-rail mounting, so mechanical fit is identical. However, verify the coil voltage and auxiliary contact configuration match your circuit — the 3RT2018-1AP01-ZX95 includes an auxiliary switch, but its electrical ratings may differ from the 3RT2017 variant.
