Reliable Protection for High-Inrush Electrical Loads
Miniature circuit breakers such as the ABB S401M-D25NP protect electrical conductors and connected equipment by automatically disconnecting the circuit when excessive current occurs. They provide protection against sustained overloads as well as rapid interruption of potentially damaging short-circuit currents.
The Type D characteristic is intended for suitable circuits where comparatively high short-duration starting currents can occur, such as those supplying certain motors, transformers and other inductive equipment. Combined with ABB's SMISSLINE TP plug-in architecture, the S401M-D25NP provides dependable protection in a modular format designed for efficient professional power distribution.
Typical Applications
- Industrial electrical distribution systems.
- Machine and automation control panels.
- Circuits supplying motors and other high-inrush loads.
- Transformer and inductive-load circuits.
- Commercial and infrastructure distribution boards.
- Industrial auxiliary power circuits.
- ABB SMISSLINE TP plug-in distribution assemblies.
