Product details

It carries a 24 VDC coil and spring-type terminals for the magnet coil, eliminating the need for screwdriver torque checks on that connection.

Rated switching capacity at 24 V is 10 A, so it handles typical 24 VDC control circuits and small motor loads without derating. At 400 V AC the switching capacity is 3 A, which covers smaller three-phase motor circuits up to that voltage. Mechanical switching frequency varies by duty class: up to 1 000 operations per hour under AC-1 resistive loads, 750 ops/h under AC-3 motor starting, and 250 ops/h under AC-4 plugging/reversing. That means the part is suited for moderate-cycle applications — a conveyor start/stop station, not a high-speed pick-and-place. Storage range extends to -55 to +80 °C, relevant for unheated warehouses. The contactor includes an integrated auxiliary switch, saving a separate add-on block for basic status feedback.

Wire terminals accept solid or stranded conductors from 0.5 to 4 mm², and up to 2x (0.5 to 4 mm²) for paralleled feeds.

Frequently asked questions

What is the closest functional alternative to this contactor?

The 3RT2017-2AP01-ZW96 is a peer in the same SIRIUS S00 family. The main difference is the coil voltage — 3RT2018-2EP01 uses 24 VDC, while the 3RT2017-2AP01-ZW96 uses a different coil voltage. Verify coil compatibility before substituting in an existing panel design.

What wire sizes does it accept?

Solid or stranded conductors from 0.5 to 4 mm², and up to 2x (0.5 to 4 mm²) for dual feeds.

Can it replace a 3RT2017-2AP01-ZW96 without rewiring?

Mechanically yes — same S00 footprint and DIN rail mount. Electrically, only if the coil voltage matches. The 3RT2018-2EP01 has a 24 VDC coil; if the original circuit used a different coil voltage, the coil supply must be changed.

What compliance documentation is available?

The part carries Siemens SIRIUS branding and is manufactured to IEC/EN standards. Specific RoHS, REACH, and UL documentation should be requested at time of RFQ; these are typically provided with the shipment from the manufacturer.
