Why Choose the ABB SU204M-Z63 Miniature Circuit Breaker?
The ABB SU204M-Z63 is a four-pole miniature circuit breaker (MCB) designed for dependable overload and short-circuit protection in sensitive industrial, automation and electrical distribution circuits. Part of the ABB System pro M compact SU200M series, it combines a 63 A rated current, Z tripping characteristic and four-pole configuration in a compact modular protective device.
Designed for UL 489 branch-circuit applications, the SU204M-Z63 provides a 10 kA short-circuit interrupting rating. Its thermal-magnetic operating principle provides automatic protection against sustained overloads and short circuits, while the Z characteristic provides a sensitive instantaneous magnetic response for circuits where comparatively low fault currents require rapid disconnection.
With a rated current of 63 A and four protected poles, the SU204M-Z63 is suitable for appropriately selected control, automation and sensitive electrical loads requiring multi-pole protection. Its modular construction supports straightforward DIN-rail installation in industrial control panels, switchboards and electrical distribution assemblies.

Sensitive Protection for Multi-Pole Electrical Circuits
Miniature circuit breakers such as the ABB SU204M-Z63 automatically disconnect a circuit when excessive current results from an overload or short circuit. This helps protect conductors, control equipment and connected electrical devices against potentially damaging overcurrents while allowing the breaker to be reset after the underlying electrical fault has been identified and corrected.
The Z characteristic provides a sensitive instantaneous magnetic response, making it useful for appropriately selected circuits where rapid disconnection at comparatively low fault-current levels is required. Combined with its 63 A rating, four-pole construction and 10 kA UL 489 interrupting capability, the SU204M-Z63 provides dependable protection for sensitive industrial, control and automation circuits.
Typical Applications
- Industrial control and automation systems.
- Sensitive electrical and electronic loads.
- Four-pole industrial branch circuits.
- Industrial machinery and control panels.
- Instrumentation and monitoring equipment.
- Switchboards and modular electrical distribution assemblies.
- Installations requiring UL 489 branch-circuit protection.
