Product details

What this 25 A 4P C-curve MCB delivers

The Schneider Electric EZ9F53425 is a 25 A, 4-pole miniature circuit breaker from the Easy9 range, built to SANS 60947-2 for distribution boards and sub-panels. The C-curve (magnetic trip at 8.5 x In ±20 %) handles motor inrush and lighting loads without nuisance tripping — typical for commercial and light industrial circuits where the start-up surge sits below 10x the rated current. Four poles give you three-phase-plus-neutral protection in one module, saving a DIN-rail position over two 2-pole breakers.

Clip-on mounting to DIN rail (35 mm profile) — no screws, no bracket. IP20 finger-safe terminals are fine for enclosed panels but not for wet environments. The grey RAL 7035 housing blends into a standard industrial enclosure.

Frequently asked questions

What is the breaking capacity of EZ9F53425?

3 kA Icu (ultimate breaking capacity) at 400 V AC 50/60 Hz, with the service breaking capacity (Ics) at the same 3 kA (100 % of Icu), both per SANS 60947-2. That matches typical secondary distribution board fault levels.

What does the C-curve mean on this MCB?

The C-curve trips magnetically at 8.5 x In ±20 %, so for a 25 A breaker that's roughly 170–255 A instantaneous trip. It's sized for circuits with moderate inrush — motor starters, fluorescent lighting banks, small transformers — without nuisance tripping on start-up.
