Why Choose the ABB S402M-D6 Miniature Circuit Breaker?
The ABB S402M-D6 is a pluggable 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit currents. Part of the ABB S400M SMISSLINE TP series, it combines current-limiting circuit protection with ABB's modular plug-in distribution architecture for professional low-voltage installations.
This circuit breaker has a rated current of 6 A, a Type D tripping characteristic and a rated short-circuit breaking capacity of 10 kA. The Type D characteristic accommodates higher short-duration starting and inrush currents than Type B or Type C devices, making the S402M-D6 suitable for appropriately designed circuits supplying equipment such as transformers, motors and other inductive loads.
The S402M-D6 provides protection across two poles and is designed for ABB's SMISSLINE TP plug-in system. Its compact 2-module construction supports efficient installation, replacement, maintenance and future circuit modification within compatible ABB distribution assemblies.

Reliable Type D Protection for High-Inrush Circuits
The ABB S402M-D6 protects electrical conductors and connected equipment by automatically interrupting excessive currents caused by overload or short-circuit conditions. The S400M range incorporates a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection, providing resettable protection for low-voltage circuits.
The Type D characteristic allows appropriately designed circuits to tolerate higher short-duration inrush currents before magnetic tripping occurs. This makes the S402M-D6 particularly relevant to circuits supplying equipment such as transformers, motors, solenoids and other inductive loads where substantial starting currents can occur.
Typical Applications
- Industrial electrical distribution systems.
- Machine and automation control panels.
- Transformer supply and control circuits.
- Motor circuits where Type D protection is appropriate.
- Solenoid and other inductive-load circuits.
- Circuits subject to relatively high short-duration starting currents.
- ABB SMISSLINE TP plug-in distribution assemblies.
