Product details

Breaking capacity is 100 kA Icu at 690 V AC 50/60 Hz per IEC 60947-2, so it handles high-fault motor circuits without cascading upstream. The MA trip unit reacts only to magnetic (short-circuit) faults; no thermal element means no nuisance tripping from motor inrush or ambient heat.

Mounts on a backplate, 105 mm wide × 161 mm high × 86 mm deep. Front connection for both line and load sides. IP40 front face, IK07 impact resistance. 0–95 % relative humidity. Operating altitude 0–2000 m without derating, 2000–5000 m with derating. Overvoltage category III.

Electrical durability: 20,000 cycles at 440 V In/2, 10,000 cycles at 440 V In, 10,000 cycles at 690 V In/2, 5,000 cycles at 690 V In. Mechanical durability: 20,000 cycles. Power dissipation per pole: 14.52 W.

Frequently asked questions

Where can I buy C25W3MA220 and how is it quoted?

Sourced to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

What is C25W3MA220 used for?

Motor protection. The magnetic-only MA trip unit provides short-circuit protection; thermal overload is handled separately by a motor starter or relay.

What is the breaking capacity of C25W3MA220?

100 kA Icu at 690 V AC 50/60 Hz per IEC 60947-2. Also 100 kA Icu at 500 V AC and 525 V AC.

What compliance documentation is available for C25W3MA220?

The breaker is certified to EN/IEC 60947-2 and suitability for isolation per that standard. Pollution degree 3 per IEC 60664-1. IP40, IK07.
