Product details

The Schneider Electric A9F06450 is a 4-pole Acti9 iC60H miniature circuit breaker rated 50 A with a B-curve trip characteristic. The 42 kA Icu at 12-133 V AC and 30 kA Icu at 220-240 V AC (EN/IEC 60947-2) give it high fault-clearing capacity for industrial panel applications; at 380-415 V AC it still interrupts 15 kA. That SCCR headroom lets you coordinate downstream without cascading failure.

Standards and deployment

Rated to both EN/IEC 60898-1 (domestic MCB standard) and EN/IEC 60947-2 (industrial circuit-breaker standard), so it qualifies for distribution boards and industrial panel feeders alike. Mounts on standard DIN rail; width is 72 mm (8 x 9 mm pitches), depth 78.5 mm, height 91 mm — fits a standard 4-pole MCB slot in any Acti9 distribution board.

Current-production part. The Acti9 iC60 series is Schneider's standard panel MCB line, widely specified for commercial and light-industrial distribution.

Frequently asked questions

What is the breaking capacity of A9F06450?

42 kA Icu at 12-133 V AC, 30 kA Icu at 220-240 V AC, 15 kA Icu at 380-415 V AC, and 10 kA Icu at 440 V AC per EN/IEC 60947-2; also rated 10 kA Icn at 400 V AC per EN/IEC 60898-1.

What standards does A9F06450 comply with?

Certified to EN/IEC 60947-2 and EN/IEC 60898-1, with suitability for isolation confirmed under both standards.
