Reliable Protection for Low Voltage Circuits

Miniature circuit breakers protect electrical installations by automatically disconnecting a circuit during overload or short-circuit conditions. The ABB S201-B25 combines thermal tripping for overload protection with electromechanical tripping for short-circuit protection, helping to reduce the risk of equipment damage and unsafe operating conditions.

The B curve characteristic is commonly used for circuits with relatively low inrush current, making this MCB suitable for general-purpose final circuits, distribution boards, consumer units and control panels in residential, commercial and light industrial environments.

Typical Applications

• Residential consumer units and distribution boards.
• Commercial electrical panels.
• General-purpose final circuits.
• Small power distribution.
• Industrial control panels.
• Low voltage circuit protection systems.
