• Motor & Transformer Loads: Type C curve suits loads with moderate inrush currents such as small motors, transformers, and fluorescent lighting.

Frequently Asked Questions

What does the Type C trip curve mean for the S201M-C25UC?

A Type C characteristic means the MCB trips instantaneously when the fault current is between 5× and 10× the rated current (25 A). This makes the S201M-C25UC well suited to loads with moderate inrush currents such as small motors and transformers, while still providing fast protection against serious short-circuit events.

What is the breaking capacity of the S201M-C25UC?

The S201M-C25UC has a rated ultimate short-circuit breaking capacity (Icu) of 10 kA, providing robust protection in circuits where fault currents could reach significant levels.

Is the S201M-C25UC compatible with ABB auxiliary accessories?

The S200MUC series is designed to accept a range of ABB snap-on accessories including auxiliary contacts, alarm contacts, and shunt/undervoltage releases, enabling flexible configuration for your distribution board.

What DIN rail width is required?

The S201M-C25UC mounts on a standard 35 mm DIN rail (EN 60715), consistent with all ABB S200-series miniature circuit breakers.
