Product details

The ABB S403M-C16 is a 3-pole miniature circuit breaker from the S400 SMISSLN family, rated at 1.600 A with a Trip Curve C characteristic.

Curve C means the magnetic trip fires at 5 to 10 times rated current (8 to 16 A), so it handles moderate inrush from contactor coils or small transformers without nuisance tripping, while still clearing a hard short quickly. The 10 kA SCCR at 240 VAC tells you it can interrupt a fault up to that level without welding contacts or cascading failure upstream — a standard rating for 240 V branch circuits in IEC 60947-2 installations.

Frequently asked questions

What is S403M-C16's rated current and trip curve?

The breaker is rated at 1.600 A continuous with a Trip Curve C characteristic — magnetic trip between 5 and 10 times rated current.

Where can I buy S403M-C16 and how is it quoted?
