Product details

The 50 Hz coil is designed for a 220 V supply at the rated frequency. Front face carries IP20 protection; the terminals themselves are IP00, so panel wiring must respect that — no live parts exposed after termination.

The AC-2 rating at 400 V is 7.5 kW, while AC-4 at the same voltage is 15.5 A — AC-4 covers reversing or plugging duty where the contactor makes and breaks under full motor current, so that figure governs the toughest switching cycles. For resistive loads (AC-12), the maximum operating current is 10 A. The mechanical life is a typical 10,000,000 operations, so it holds up in high-cycle applications like conveyor diverters or pump sequencing. Wire sizing is generous: main terminals accept solid or stranded conductors from 0.5 mm² up to 4 mm² (2x per clamp), or AWG 16 to 8. For type 2 coordination (no-weld condition), the required fuse is gL/gG 25 A; for type 1 coordination, 63 A.

Frequently asked questions

What is the price of 3RT1025-1AN00?

Pricing for the 3RT1025-1AN00 is confirmed at quote time against an RFQ. Submit a request for current market pricing and availability.

What is the replacement for 3RT1025-1AN00?

No official replacement has been announced — the part is still active. If a cross-reference is needed, the closest functional peer in the SIRIUS family is the 3RT6024-1AP00, but verify your specific duty and coil voltage before substituting.

Where can I buy 3RT1025-1AN00?

The 3RT1025-1AN00 is sourced to order against an RFQ through independent distribution. Submit a request for a quote; availability and lead time are confirmed at that point.

What are the specifications of 3RT1025-1AN00?

It is a 3-pole power contactor, size S0, with 3 NO main contacts, screw terminals, 45 mm wide, 85 mm high, 91 mm deep, rated AC-2 7.5 kW at 400 V, AC-4 15.5 A at 400 V, mechanical life 10,000,000 operations, operating temperature -25 to +60 °C, pollution degree 3, front IP20.

What is the rated current of 3RT1025-1AN00?

The rated current depends on duty: AC-2 7.5 kW at 400 V, AC-4 15.5 A at 400 V, AC-12 maximum 10 A. For auxiliary switching at 24 V it is 10 A, at 230 V it is 6 A, at 400 V it is 3 A.
