2CDS271527R0467 ABB SU201DC-K16 16 A 1P Type K DC Miniature Circuit Breaker 14 kA

Why Choose the ABB SU201DC-K16 Miniature Circuit Breaker?

The ABB SU201DC-K16 is a specialised single-pole DC miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection for commercial and industrial DC electrical systems. Part of the ABB SU200DC series, this model combines a 16 A rated current, K tripping characteristic and high short-circuit rating for dependable protection of DC power, control and auxiliary circuits.

The K characteristic is particularly suitable for circuits supplying equipment that can produce elevated starting or transient currents during normal operation. This makes the SU201DC-K16 well suited to motors, transformers, solenoids and other inductive loads where tolerance of functional current peaks is required while maintaining effective conductor protection.

With a 14 kA short-circuit current rating, single-pole configuration and dedicated DC construction, the SU201DC-K16 provides robust branch-circuit protection in a compact modular format. Its thermal-magnetic operating principle automatically disconnects the circuit under overload and short-circuit conditions, helping protect wiring and connected equipment in demanding DC installations.

Reliable Protection for DC Power and Control Circuits

Miniature circuit breakers such as the ABB SU201DC-K16 automatically interrupt excessive current caused by overload or short-circuit conditions, helping protect electrical conductors and connected equipment. The thermal release responds to sustained overloads, while the magnetic release provides rapid disconnection when severe fault currents occur.

The K characteristic makes the SU201DC-K16 especially useful for electrical loads that draw higher current during starting or energisation without indicating a fault. This characteristic supports dependable protection of motors, transformers, solenoids and similar equipment while helping minimise unwanted tripping caused by normal transient current peaks.

• Industrial DC power and control circuits.
• DC motor circuits.
• Transformer auxiliary circuits.
• Solenoid and electromagnetic loads.
• Industrial automation systems.
• Machine control and DC distribution panels.
• Circuits with elevated functional starting or transient currents.
