Why Choose the ABB S202M-K5UC Miniature Circuit Breaker?

The ABB S202M-K5UC is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions in demanding AC and DC applications. As part of the ABB S200 M UC universal current series, it combines a 5 A rated current with K-characteristic tripping and a high short-circuit breaking capacity.

Developed for applications requiring dependable protection at higher AC and DC voltages, the S200 M UC range extends ABB's System pro M compact platform with flexible circuit protection for industrial, transportation and traction-related electrical systems. The S202M-K5UC provides two-pole protection in a compact DIN rail format and is compatible with System pro M compact accessories.

With a rated current of 5 A, K tripping characteristic and 10 kA short-circuit breaking capacity, the S202M-K5UC is well suited to industrial circuits where loads may produce higher starting or inrush currents. Its universal-current construction supports both AC and DC applications, including operation at 400 V AC and up to 440 V DC.

Reliable AC/DC Circuit Protection

Miniature circuit breakers such as the ABB S202M-K5UC automatically disconnect a circuit when excessive current occurs as a result of an overload or short circuit. This helps protect conductors, wiring and connected electrical equipment while allowing the breaker to be reset after the fault has been identified and corrected.

The S200 M UC series is engineered for universal-current applications and provides flexible protection for both alternating-current and direct-current circuits. Its K characteristic is particularly useful for industrial circuits with loads that can produce higher starting or inrush currents, while its high short-circuit capacity and international approvals support use across demanding electrical installations.

Typical Applications

• DC and traction electrical systems.
• Industrial control and automation circuits.
• Motor and transformer auxiliary circuits.
• Control panels and electrical distribution boards.
• Machinery and industrial equipment.
• Transportation and railway-related electrical systems.
