Why Choose the ABB SU201MR-K6 Miniature Circuit Breaker?
The ABB SU201MR-K6 is a compact and reliable single-pole miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for industrial machinery, automation systems and branch circuits. As part of the ABB SU200MR / System pro M compact range, it combines a 6 A rated current, K tripping characteristic and UL 489 compliance in a modular DIN rail format.
The SU201MR-K6 uses thermal-magnetic protection to respond to sustained overloads and short-circuit faults. Its K characteristic is particularly suited to circuits containing motors, transformers, solenoids and other inductive equipment with elevated starting or inrush currents, helping reduce unwanted tripping during normal operation while maintaining dependable circuit protection.
With a single-pole configuration, 6 A rated current and 10 kA UL 489 interrupting rating, the SU201MR-K6 is well suited to industrial control and auxiliary circuits requiring recognised branch-circuit protection. Its compact construction enables efficient installation inside machinery cabinets, automation panels and electrical distribution assemblies.

Reliable Protection for Industrial Control Circuits
Miniature circuit breakers such as the ABB SU201MR-K6 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 mechanism provides rapid interruption during short-circuit faults.
The K characteristic provides increased tolerance of normal starting and inrush currents compared with more sensitive tripping characteristics. This makes the SU201MR-K6 particularly useful for industrial control equipment, motors, transformers, solenoids and other inductive loads requiring dependable overcurrent protection.
Typical Applications
- Industrial automation and control panels.
- Motor and inductive-load circuits.
- Transformer and solenoid circuits.
- Machine control and auxiliary circuits.
- Branch-circuit protection.
- OEM machinery and manufacturing equipment.
