Product details

It carries a 100 kA Icu at 240 V AC and 70 kA Icu at 415 V AC per EN/IEC 60947-2, so it safely interrupts high fault currents on motor branch circuits without cascading upstream. The MA trip responds only to short-circuit events — no thermal overload element — meaning the upstream motor starter or soft starter handles the overload protection.

The 3D protected poles description indicates all three poles are protected. Breaking capacity varies with system voltage: 100 kA at 240 V, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, and 10 kA at 690 V AC. Under UL 60947-4-1 it is rated 85 kA at 240 V, 65 kA at 480 V, and 15 kA at 600 V AC. This makes the H breaking capacity code suitable for high-fault installations like large motor control centres. IP40 enclosure protection and IK07 impact resistance suit it for panel mounting where occasional tool contact is expected.

Frequently asked questions

What is the breaking capacity of C25H3MA150 at 415 V?

70 kA Icu at 380/415 V AC 50/60 Hz conforming to EN/IEC 60947-2, and 65 kA Icu at 480 V AC under UL 60947-4-1.

What protection does the MA trip unit provide?

The MA trip unit provides magnetic-only short-circuit protection (I), with no thermal overload element. Overload protection must be handled by an upstream motor starter or soft starter.
