Why Choose the ABB SU201M-Z63 Miniature Circuit Breaker?
The ABB SU201M-Z63 is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for sensitive electrical circuits, industrial machinery and automation systems. As part of the ABB SU200M / System pro M compact range, it combines a 63 A rated current, Z tripping characteristic and UL 489 compliance in a compact modular format.
The SU201M-Z63 uses thermal-magnetic protection to respond to sustained overloads and short-circuit faults. Its Z characteristic provides sensitive instantaneous magnetic operation, making it suitable for circuits where rapid fault-current disconnection is required to protect electronic equipment, control systems and other sensitive electrical loads.
With a single-pole configuration, 63 A rated current and 10 kA UL 489 interrupting rating, the SU201M-Z63 provides dependable branch-circuit protection for industrial installations. Its compact modular construction enables straightforward integration into DIN rail control and distribution panels.

Sensitive Protection for Electrical and Electronic Circuits
Miniature circuit breakers such as the ABB SU201M-Z63 automatically disconnect electrical circuits when excessive current occurs because of an overload or short circuit. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid interruption during short-circuit faults.
The Z characteristic provides sensitive instantaneous tripping compared with characteristics intended for loads with substantial starting currents. This makes the SU201M-Z63 particularly useful for electronic equipment, control circuits and other applications where rapid response to fault current is important.
Typical Applications
- Industrial automation and control panels.
- Electronic equipment and sensitive electrical loads.
- PLC and machine control circuits.
- Branch-circuit protection.
- Electrical control and distribution cabinets.
- OEM machinery and manufacturing equipment.
