Overcurrent circuit breaker, 3P+N, C characteristic, 32A, 6kA, AC | S203-C32NA 2CDS253103R0324

Reliable protection of electrical installations with S203-C32NA circuit breaker

This three-pole circuit breaker with a connected neutral pole (3P+N) is a key element of every safe and reliable electrical installation. Designed to protect against overloads and short circuits, it provides peace of mind for both installers and end-users. Characteristic C makes it ideal for circuits with devices generating inrush currents, such as motors or transformers – it allows it to react more slowly to short current surges, while effectively protecting against long-term overloads. The rated short-circuit breaking capacity of 6kA at 400V guarantees effective disconnection in the event of a failure.

Solid construction and universal application

The S203-C32NA circuit breaker is characterized by a compact design, taking up 4 modules on a DIN rail. Its embedding depth of 69 mm allows for easy installation in standard distribution boards. Adapted to work in a wide range of ambient temperatures (-25°C to +55°C) and with wires with a cross-section from 0.75 mm² to 35 mm² (solid) or 25 mm² (stranded), it offers great flexibility in the selection of wires and working conditions. The degree of protection IP20 provides basic protection against accidental contact.

Safety confirmed by norms and standards

The circuit breaker meets the requirements of overvoltage category III and pollution degree 3, which means it is adapted to work in difficult industrial and commercial conditions. It has a rated insulation voltage Ui of 440V and a rated impulse withstand voltage Uimp of 4kV. The rated short-circuit breaking capacity Icu is as high as 10kA at 400V and 20kA at 230V (according to IEC 60947-2), which confirms its high effectiveness in emergency situations. The energy limitation class is 3, which provides additional safety in the event of an electric arc. The possibility of expanding with additional equipment increases the functionality of the device and allows it to be adapted to the specific needs of the installation.
