Why Choose the ABB SUP403M-K3 Miniature Circuit Breaker?
The ABB SUP403M-K3 is a pluggable 3-pole miniature circuit breaker (MCB) designed for branch circuit protection within ABB SMISSLINE TP electrical distribution systems. As part of the ABB SUP400 K series, it provides protection against overload and short-circuit currents while combining UL 489 compliance with the modular plug-in architecture of the SMISSLINE TP system.
This MCB has a rated current of 3 A, a K tripping characteristic and a short-circuit interrupting rating of 10 kA. Its three-pole configuration makes it suitable for three-phase branch circuits, while the K characteristic is designed for applications where connected equipment may produce increased starting or inrush currents.
The SUP403M-K3 is designed for 277/480 V AC systems and contacts directly with the compatible SMISSLINE TP socket-base system. Its compact three-module construction provides efficient three-pole protection while supporting straightforward installation and circuit configuration in professional industrial and commercial distribution assemblies.

Reliable Three-Phase Branch Circuit Protection
Miniature circuit breakers protect cables and electrical circuits against excessive current caused by overload and short-circuit conditions. The ABB SUP403M-K3 combines these protective functions with a K tripping characteristic, making it suitable for appropriate three-phase circuits where connected equipment may draw increased current during starting or energisation.
The SUP403M-K3 contacts directly through the ABB SMISSLINE TP socket-base system, supporting a modular approach to electrical distribution. The plug-in architecture helps simplify panel assembly and circuit configuration, while the three-pole format provides coordinated protection for three-phase branch circuits in UL 489 applications.
Typical Applications
- ABB SMISSLINE TP electrical distribution systems.
- UL 489 branch circuit protection.
- Three-phase industrial branch circuits.
- Industrial electrical distribution panels.
- Commercial electrical distribution systems.
- Control and automation panels.
- Circuits supplying suitable loads with elevated starting or inrush currents.
