Overcurrent circuit breaker, 3P+N, B characteristic, 16A, 10kA, AC | S203M-B16NA 2CDS273103R0165

Reliable protection of electrical installations – 3P+N circuit breaker

This three-pole circuit breaker with a neutral pole, with B characteristic and a rated current of 16A, is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. The 3P+N (three phases plus neutral) design makes it ideal for protecting circuits in residential and commercial buildings.

Universal application and high performance

This circuit breaker, with a width of 4 modules, is used in electrical switchboards, providing reliable protection for various loads. The B characteristic means that the circuit breaker reacts quickly to an increase in short-circuit current, but is more tolerant of short-term current surges during device start-up – which is particularly important when connecting motors or transformers. The rated short-circuit breaking capacity of 10kA at 400V and 25kA at 230V (according to IEC 60947-2) guarantees safety even in the event of serious failures.

Solid construction and compliance with standards

The circuit breaker is designed for long-term and trouble-free operation. Its housing made of high-quality materials provides resistance to mechanical damage and external factors. It meets the requirements of overvoltage category III and pollution degree 3, which confirms its reliability in difficult environmental conditions. The rated impulse withstand voltage of 4kV further increases safety. The ability to mount additional equipment allows you to adapt the functionality of the circuit breaker to the specific needs of the installation. The cross-section of solid conductors from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm² ensures compatibility with various types of cables.
