Why Choose the ABB S401M-D16 Miniature Circuit Breaker?
The ABB S401M-D16 is a current-limiting single-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection in electrical distribution systems. As part of the ABB SMISSLINE TP S400M series, it combines robust circuit protection with the convenient plug-in architecture of the SMISSLINE TP distribution system.
This miniature circuit breaker incorporates two complementary tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. Its Type D tripping characteristic makes it particularly suitable for circuits supplying equipment with comparatively high starting or inrush currents.
With a rated current of 16 A, a rated short-circuit capacity of 10 kA and a 230 V AC rated operational voltage, the S401M-D16 provides reliable protection in a compact one-module format. Its plug-in design is intended specifically for compatible ABB SMISSLINE TP assemblies, supporting efficient installation and servicing in commercial, industrial and critical-power applications.

Reliable Circuit Protection for High-Inrush Loads
Miniature circuit breakers such as the ABB S401M-D16 protect electrical installations by automatically interrupting damaging overcurrents. Its delayed thermal mechanism responds to sustained overloads, while the electromechanical mechanism provides rapid operation during short-circuit faults.
The Type D characteristic allows the S401M-D16 to accommodate higher transient starting currents than more sensitive MCB characteristics, making it useful for appropriately engineered circuits supplying equipment such as motors, transformers and other inductive loads. The SMISSLINE TP plug-in architecture also supports efficient integration into modern commercial and industrial distribution systems.
Typical Applications
- ABB SMISSLINE TP plug-in distribution boards.
- Industrial machinery and control systems.
- Motor and inductive-load circuits with high starting currents.
- Transformer and power-supply circuits.
- Commercial and industrial electrical distribution.
- Critical-power and infrastructure installations.
