ABB SUP403M-K2 is a 2 A 3-pole K-characteristic SMISSLINE TP miniature circuit breaker with a 10 kA rated breaking capacity for UL 489 branch-circuit protection.
£161.98
The ABB SUP403M-K2 is a high-performance 3-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for cables, conductors and electrical circuits. As part of the ABB SMISSLINE TP SUP400M series, it combines a 2 A rated current, K tripping characteristic and high breaking capacity with ABB's convenient plug-in distribution technology.
Designed for branch-circuit protection according to UL 489, the SUP403M-K2 features a K tripping characteristic, making it particularly suitable for circuits supplying equipment with elevated starting or inrush currents. Its SMISSLINE TP plug-in construction enables direct connection to compatible socket-base systems for efficient installation and maintenance.
With a rated current of 2 A, a 3-pole configuration and a rated breaking capacity of 10 kA according to UL 489, the SUP403M-K2 is designed for 277–480 V AC systems. ABB order code 2CCG000119R0001 uniquely identifies this configuration.
Miniature circuit breakers such as the ABB SUP403M-K2 automatically interrupt electrical circuits when excessive current or a short circuit occurs. This helps protect cables, conductors, connected equipment and electrical distribution infrastructure against damage caused by potentially hazardous overcurrent conditions.
The SMISSLINE TP system uses modular plug-in distribution technology to simplify the installation and replacement of compatible protective devices. Combined with its K tripping characteristic and three-pole construction, the SUP403M-K2 provides a practical protection solution for three-phase circuits where normal starting currents may be higher than continuous operating current.
