The Schneider Electric A9N3P04CGN is a miniature circuit breaker from the Acti9 xC60 range, designed for distribution in AC networks at 50/60 Hz. It is a 3-pole device rated at 4 A with a C-curve (magnetic tripping between 5 and 10 times In), thermal-magnetic trip technology, and a breaking capacity of 10 kA at both 240 V and 415 V AC per IS/IEC 60898-1.
The housing is 54 mm wide (6 x 9 mm pitches), 85 mm tall, and 77.5 mm deep, fitting a standard modular enclosure footprint. Wire stripping length is 13 mm for top or bottom connection.
Durability and auxiliary features
Rated for 20,000 electrical and 20,000 mechanical cycles. The toggle switch provides ON/OFF indication, and a contact position indicator shows the true state of the contacts. Earth-leakage protection requires a separate block — this is the MCB only, not an RCBO.
