Why Choose the ABB S401M-D6 Miniature Circuit Breaker?
The ABB S401M-D6 is a high-performance single-pole miniature circuit breaker (MCB) designed for reliable overcurrent protection within the ABB SMISSLINE TP plug-in distribution system. With a 6 A rated current, Type D tripping characteristic and 10 kA rated short-circuit capacity, it provides dependable protection against overload and short-circuit conditions.
As part of the ABB S400M series, the S401M-D6 combines thermal-magnetic circuit protection with the flexibility of ABB's SMISSLINE TP plug-in architecture. The plug-in design enables efficient installation and replacement of compatible protective devices while supporting modular expansion of commercial and industrial distribution systems.
The Type D characteristic is intended for circuits with comparatively high starting or inrush currents, making the S401M-D6 suitable for applications involving transformers, motors, solenoids and similar inductive loads. Its compact one-module format provides high-performance protection while conserving valuable distribution-board space.

Reliable Protection for High-Inrush Loads
Miniature circuit breakers protect electrical conductors and connected equipment by automatically disconnecting a circuit when overload or short-circuit currents exceed safe limits. The ABB S401M-D6 combines thermal overload protection with fast magnetic short-circuit protection to provide dependable fault interruption.
Its Type D characteristic allows higher transient starting currents before magnetic operation than Type B or Type C breakers, helping to reduce unwanted tripping on suitable inductive loads. This makes the S401M-D6 particularly useful where equipment such as motors, transformers or solenoids produces significant but legitimate inrush current during normal starting.
Typical Applications
- Motor and actuator control circuits.
- Transformer-fed circuits.
- Solenoids and other inductive loads.
- Industrial machinery and automation systems.
- Commercial and industrial distribution boards.
- ABB SMISSLINE TP plug-in distribution assemblies.
