Overcurrent circuit breaker, 3P, Z characteristic, 1.6A, 25kA, AC | S303P-Z1.6 2CDS383001R0258

Protection of installations and devices – ABB S303P series overcurrent circuit breaker

This three-pole overcurrent circuit breaker from ABB with Z characteristic is a reliable protection for your electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe operation and long-term system stability. The Z characteristic means that the circuit breaker reacts very quickly to current increase, which is particularly important in circuits with sensitive electronics or where high selectivity is required.

This circuit breaker is characterized by a rated current of 1.6A and a short-circuit interrupting capacity of 25kA, making it an ideal solution for various applications – both in residential and commercial buildings. Mounting on a TH35 rail allows for quick and easy installation in a distribution board. The rated impulse withstand voltage of 6kV guarantees resistance to overvoltages, and the IP20 degree of protection provides basic protection against touch and dust.

Parameters ensuring safety and functionality

The S303P-Z1.6 circuit breaker has been designed with the requirements of modern electrical installations in mind. Its compact width of 3 modules saves space in the distribution board. The cross-section of the connectable multi-wire cable up to 25 mm² and single-wire cable up to 35 mm² allows connection of cables of different thicknesses, adapting to the specifics of the installation. The rated short-circuit breaking capacity Icu at 100kA at 400V and Icn at 25kA at 400V guarantee effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.

Additionally, the circuit breaker has overvoltage category IV, which means it is adapted to operate in installations exposed to atmospheric or operational overvoltages. The frequency range of 50-60 Hz ensures compatibility with most power grids. The possibility of mounting additional equipment increases the functionality of the device and allows it to be adapted to individual user needs. Made of high-quality materials, the circuit breaker ensures long-lasting and reliable operation at an ambient temperature from 0 to 70°C.
