Why Choose the ABB S401M-D63NP Miniature Circuit Breaker?
The ABB S401M-D63NP is a high-performance miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in commercial, industrial and critical power distribution systems. As part of the ABB SMISSLINE TP S400M series, it combines a protected neutral configuration with the modular plug-in installation advantages of the SMISSLINE system.
This current-limiting circuit breaker uses a delayed thermal tripping mechanism for overload protection and an electromagnetic tripping mechanism for short-circuit protection. Its Type D tripping characteristic is designed for compatible circuits with high inrush currents, including selected motors, transformers and other equipment with demanding starting characteristics.
With a rated current of 63 A, a rated voltage of 230 V AC and a 10 kA rated short-circuit capacity, the S401M-D63NP provides dependable circuit protection in a compact 1P+NP protected-neutral configuration. Its plug-in format enables direct integration into compatible ABB SMISSLINE TP distribution systems.

Reliable Protection for High-Inrush Electrical Circuits
Miniature circuit breakers such as the ABB S401M-D63NP protect electrical wiring and connected equipment against excessive current. A delayed thermal tripping mechanism responds to sustained overload conditions, while electromagnetic tripping provides rapid disconnection during short-circuit faults.
The Type D characteristic makes the S401M-D63NP suitable for compatible circuits where normal starting currents can be significantly higher than steady-state operating current. Combined with ABB’s SMISSLINE TP plug-in architecture, it provides a practical protection solution for demanding commercial and industrial electrical distribution applications.
Typical Applications
- Industrial control and automation panels.
- Compatible motor circuits with high starting currents.
- Transformer circuits.
- Machinery and industrial equipment distribution.
- Commercial electrical distribution boards.
- Critical power distribution systems.
