Product details

It is designed for outgoing circuits in TN-S and TT earthing systems on 230 V AC, 50 Hz networks. The recloser logic handles transient earth faults: after a trip, it waits 10 seconds, then attempts a restart. If the fault persists, it stops after 3 consecutive restart attempts with a minimum 180-second interval between closings. It monitors for insulation faults between attempts and will not restart if a permanent fault is present.

The 2-pole device occupies 6 module pitches (9 mm each), so 54 mm of rail width. Neutral is on the left.

Listed as current production.

Frequently asked questions

Where can I buy A9CR4225 and how do I get a price?

The A9CR4225 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is A9CR4225's listed depth on this component line?

The depth is 82 mm.

What is A9CR4225's listed reset on this component line?

The reset type is fault reset earth leakage — after an earth fault trip, the recloser automatically attempts to reset and reclose the circuit.

What compliance documentation does this brand provide for A9CR4225?

The device complies with EN 50557 (requirements for automatic reclosing devices for RCCBs). It is rated for 230 V AC 50 Hz, with insulation voltage 500 V, and carries IP20 protection.
