2CDS272061R0607 ABB S202M-K63UC MCB 10kA 2P Type K 63A

Why Choose the ABB S202M-K63UC Miniature Circuit Breaker?

The ABB S202M-K63UC is a high-performance two-pole universal-current miniature circuit breaker (MCB) designed to protect AC and DC electrical circuits against overloads and short circuits. Part of the ABB System pro M compact S 200 M UC series, it combines flexible AC/DC operation with robust circuit protection for industrial, transportation and electrical distribution applications.

This model combines a 63 A rated current with a Type K tripping characteristic. Type K protection is particularly suited to motors, transformers, solenoids and other inductive loads that can produce elevated starting currents, helping reduce unwanted tripping during normal start-up while maintaining effective overload and short-circuit protection.

With its two-pole configuration, the S202M-K63UC is suitable for operation at 400 V AC and up to 440 V DC and provides a 10 kA rated short-circuit breaking capacity. Its ultimate short-circuit breaking capacity reaches 25 kA at 220 V DC and 10 kA at 440 V DC. ABB order code 2CDS272061R0607 identifies this exact 63 A Type K configuration.

Reliable Type K Protection for AC and DC Circuits

The ABB S202M-K63UC automatically disconnects the protected circuit when excessive current results from an overload or short circuit. Its circuit-protection design provides dependable overload protection together with rapid interruption of high fault currents, helping protect conductors, machinery and connected electrical equipment from damaging overcurrent conditions.

The Type K characteristic is particularly useful for inductive equipment that can draw substantial current during normal start-up. Combined with the universal-current capability and high short-circuit performance of the S 200 M UC platform, this makes the S202M-K63UC a practical solution for motors, transformers, solenoids, industrial auxiliary circuits and other demanding AC or DC applications.

Typical Applications

• Industrial AC and DC distribution systems.
• Motor and inductive-load circuits.
• Transformer and solenoid circuits.
• Control and automation panels.
• Higher-current DC auxiliary power systems.
