Overcurrent circuit breaker, 1P, Z characteristic, 2A, 25kA, AC | S301P-Z2 2CDS381001R0278

Protection of installations and devices – reliable ABB circuit breaker

This single-pole circuit breaker from ABB with Z characteristic is a key element in protecting the electrical installation. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage and fires. The Z characteristic means that the circuit breaker reacts very quickly to an increase in current, which is particularly important in circuits with sensitive electronics or where high selectivity is required.

This circuit breaker is designed to operate in AC/DC installations with a rated voltage of 240V. Its rated current is 2A, and the short-circuit interrupting capacity (Icn) at 230V is 25kA, guaranteeing its reliable operation even in difficult conditions. The rated ultimate short-circuit breaking capacity Icu at 230V is as high as 100kA. A width of 1 module makes it easy to mount in electrical distribution boards.

Construction features and application

The circuit breaker is made of high-quality materials, ensuring its durability and reliability. The IP20 degree of protection protects against finger contact and solid objects larger than 12.5 mm. The cross-section of the connected multi-wire cable is from 0.75 mm² to 25 mm², and the single-wire cable from 0.75 mm² to 35 mm², which provides flexibility in cable selection. The ambient temperature in operating conditions is in the range of 0°C to 70°C, which allows it to be used in various environments.

This model is used to protect lighting circuits, socket circuits and other loads with low power consumption. It is ideal for both home and commercial installations where high reliability and safety are required. The possibility of mounting additional equipment increases the functionality of the circuit breaker and allows it to be adapted to individual user needs. The rated impulse withstand voltage is 6kV and the surge category IV provides additional protection against disturbances in the electrical network.
