Why Choose the ABB SU203M-K60 Miniature Circuit Breaker?
The ABB SU203M-K60 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable branch-circuit overcurrent and short-circuit protection in industrial and commercial electrical installations. As part of the ABB System pro M compact SU200M series, it combines compact modular construction with UL 489 compliance for demanding electrical distribution and machine control applications.
Featuring a K tripping characteristic, the SU203M-K60 is particularly suited to circuits supplying inductive loads with higher starting currents, including motors, transformers and industrial control equipment. Its three protected poles provide simultaneous protection and isolation of three-phase circuits, while its DIN rail format enables straightforward integration into control panels and distribution assemblies.
With a rated current of 60 A and a 10 kA UL 489 interrupting rating, the SU203M-K60 provides dependable protection for industrial branch circuits. Its thermal-magnetic operating principle and Type K response make it a practical choice for machinery, automation equipment and electrical systems where normal load inrush must be accommodated while maintaining effective fault protection.
Key Advantages
- Reliable UL 489 branch-circuit protection for industrial and commercial installations.
- 60 A rated current for three-phase electrical circuits.

Reliable Protection for Inductive Loads
Miniature circuit breakers such as the ABB SU203M-K60 automatically interrupt a circuit when excessive current occurs because of an overload or short circuit. Thermal-magnetic operation provides dependable resettable protection for conductors and connected equipment while allowing the breaker to be returned to service after the cause of a trip has been corrected.
The K characteristic is designed for applications where normal starting currents can be higher than those encountered with predominantly resistive loads. This makes the SU203M-K60 particularly useful in industrial control, motor and transformer circuits where tolerance of normal inrush current is required alongside effective overcurrent protection.
Typical Applications
- Industrial electrical control panels.
- Three-phase branch-circuit protection.
- Motor and inductive-load circuits.
- Transformer and control circuits.
- Machinery and factory automation systems.
- OEM equipment and machine building.
