Why Choose the ABB S401P-B3NP Miniature Circuit Breaker?

The ABB S401P-B3NP is a high-performance miniature circuit breaker (MCB) with protected neutral designed for reliable overload and short-circuit protection in electrical distribution systems. As part of the ABB S400P series for the SMISSLINE plug-in system, it combines a B tripping characteristic with a compact plug-in format for efficient installation and dependable circuit protection.

This miniature circuit breaker protects cables and conductors against overload and short-circuit conditions while providing convenient integration into compatible SMISSLINE distribution assemblies. The plug-in connection system simplifies installation and replacement, making the S401P-B3NP well suited to professional commercial and industrial electrical distribution applications.

With a rated current of 3 A, a B tripping characteristic and an ultimate short-circuit breaking capacity of 40 kA, the S401P-B3NP provides robust protection for low-current circuits. Its 1P+N protected-neutral configuration occupies two modules and combines phase and neutral protection in a compact SMISSLINE-compatible device.
