Why Choose the ABB SU201DC-K1 Miniature Circuit Breaker?
The ABB SU201DC-K1 is a specialised DC miniature circuit breaker (MCB) designed to protect cables, conductors and electrical circuits against overloads and short circuits. Part of the ABB SU200DC series, this single-pole circuit breaker is intended for dependable protection in commercial, industrial, auxiliary and DC electrical applications.
The SU201DC-K1 features a Type K tripping characteristic, a rated current of 1 A and a 14 kA short-circuit current rating (SCCR) according to UL 489. The K characteristic is designed to tolerate functional peak currents while still providing effective protection for cables and connected circuits.
With its single-pole configuration and suitability for DC circuits up to 125 V DC, the SU201DC-K1 provides a compact solution for low-current DC protection. It complies with UL 489 and CSA C22.2 No. 5, making it suitable for installations requiring recognised North American circuit-breaker standards.

Reliable Circuit Protection for DC Electrical Systems
Miniature circuit breakers such as the ABB SU201DC-K1 automatically interrupt a circuit when excessive current results from an overload or short circuit. This helps protect cables, conductors and connected equipment while allowing the circuit breaker to be reset after the electrical fault has been identified and corrected.
The ABB SU200DC K-characteristic range is designed for demanding DC circuit-protection duties. Its combination of Type K tripping behaviour, a 14 kA SCCR and compliance with UL 489 and CSA C22.2 No. 5 makes the SU201DC-K1 suitable for low-current DC circuits where dependable protection and tolerance of functional peak currents are required.
Typical Applications
- DC electrical distribution systems.
- Industrial control and automation circuits.
- Low-current auxiliary circuits.
- Commercial and industrial DC installations.
- Electronic circuits requiring overload and short-circuit protection.
- DC circuits subject to functional peak or transient currents.
