Overcurrent circuit breaker, 3P, K characteristic, 40A, 6kA, AC | S203-K40 2CDS253001R0557

Reliable protection of electrical installations with S200 series circuit breaker

This three-pole circuit breaker with K characteristic is a key element of every safe and reliable electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and people. It is a device designed for mounting on a DIN rail, occupying 3 modules in width.

This circuit breaker, with a rated current of 40A and a short-circuit breaking capacity of up to 6kA at 400V, is perfect for protecting electrical circuits in residential and commercial buildings. The K characteristic means that the circuit breaker reacts more slowly to short-term current surges, which is particularly important when connecting devices with motors or other elements generating high starting currents – it will not cause unnecessary disconnection of the circuit when starting such devices.

Solid construction and high resistance

The circuit breaker is designed for durability and reliability. Its housing is made of high-quality materials, providing resistance to mechanical damage and environmental conditions. The IP20 degree of protection guarantees protection against accidental contact. The device operates in a wide range of ambient temperatures, from -25°C to 55°C, making it suitable for use in various conditions. The rated impulse withstand voltage of 4kV provides additional safety in the event of overvoltage.

Installation and compatibility

The circuit breaker is easy to install on a standard DIN rail. It accepts solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm². The possibility of additional equipment allows you to adapt the functionality of the circuit breaker to specific installation needs. Energy limitation class 3 and surge category III indicate its suitability for installations with increased safety requirements. Compliance with EN 60898 and IEC 60947-2 standards guarantees its safety and reliable operation.
