Overcurrent circuit breaker, 2P, Z characteristic, 6A, 10kA, AC/DC | S202M-Z6UC 2CDS272061R0378

Reliable protection of electrical installations – ABB S202M-Z6UC circuit breaker

This two-pole ABB S202M-Z6UC circuit breaker with Z characteristic is a key element ensuring safety in every electrical installation. Designed for both home and professional use, it effectively protects circuits against overloads and short circuits. Its compact dimensions (2 modules wide) make it easy to install in distribution boards, and its solid construction guarantees long-lasting and trouble-free operation.

Functionality and technical parameters

The circuit breaker is characterized by a rated current of 6A and a short-circuit interrupting capacity of up to 10kA at 230V and 15kA at 400V. The Z characteristic provides a quick response to current increase, which is particularly important in circuits with devices with high inrush current, such as motors. The rated impulse withstand voltage of 4kV increases resistance to overvoltage. The circuit breaker is designed to operate at ambient temperatures from 0 to 55°C and has an IP20 degree of protection. The possibility of connecting wires with a cross-section from 0.75 mm² to 25 mm² (multi-stranded) or 0.75 mm² to 35 mm² (solid) provides installation flexibility. The energy limitation class is 3, which indicates a high level of safety in the event of an electric arc.

Installation and application

The S202M-Z6UC circuit breaker is designed for mounting on a TH35 rail. Its versatility makes it applicable in many areas:

• Home installations: protection of lighting, socket and other receiver circuits.
• Commercial buildings: securing installations in offices, shops and other public facilities.
• Industry: protection of circuits powering electrical devices with lower power.
• Distribution boards: ideal for building safe and reliable electrical distribution boards.

Thanks to the possibility of additional equipment, the functionality of the circuit breaker can be adapted to specific installation needs.
