Why Choose the ABB SU204M-K2 Miniature Circuit Breaker?
The ABB SU204M-K2 is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide reliable branch-circuit protection against overloads and short circuits in commercial and industrial electrical installations. As part of the ABB SU200M series, it combines compact modular construction with UL 489 compliance for dependable protection in demanding electrical distribution and automation applications.
Featuring a 2 A rated current, K tripping characteristic and 10 kA interrupting rating according to UL 489, the SU204M-K2 is particularly suited to circuits where tolerance of normal starting or inrush currents is required. Its four-pole configuration enables coordinated protection and switching across multi-conductor circuits.
The SU204M-K2 is designed for branch-circuit protection in industrial and commercial systems and installs on standard DIN rail inside distribution boards and control panels. Its System pro M compact format makes efficient use of panel space while providing the dependable protection associated with ABB circuit protection devices.

Reliable Branch-Circuit Protection
Miniature circuit breakers such as the ABB SU204M-K2 automatically disconnect a circuit when excessive current results from an overload or short circuit. This helps protect electrical conductors and connected equipment while allowing the breaker to be reset after the cause of the fault has been identified and corrected.
The K characteristic is particularly useful for electrical loads that can produce elevated starting currents during normal operation. Combined with its four-pole construction and UL 489 branch-circuit protection capability, the SU204M-K2 provides a practical solution for industrial control, machinery and electrical distribution systems.
Typical Applications
- Industrial electrical distribution panels.
- Machine and automation control panels.
- Motor and inductive-load control circuits.
- Industrial control and instrumentation circuits.
- Commercial electrical distribution systems.
- UL 489 branch-circuit protection applications.
