Overcurrent circuit breaker, 3P, Z characteristic, 2A, 25kA, AC | S303P-Z2 2CDS383001R0278

Protection of installations and devices – ABB S303P series circuit breaker

This three-pole ABB circuit breaker from the S303P series is a reliable protection for your electrical installation. Designed to protect against the effects of overloads and short circuits, it ensures safe operation and longer life of connected devices. Characteristic Z guarantees a quick response in the event of sudden current surges, which is particularly important in applications requiring high selectivity.

This circuit breaker is characterized by a high short-circuit breaking capacity of up to 25kA at 400V, making it suitable for use in residential, commercial and industrial facilities. The rated current of 2A makes it ideal for protecting circuits with lower power consumption, such as lighting or electrical outlets.

The short-circuit breaking capacity reaches 25kA at 400V, effectively protecting against damage caused by a short circuit. Characteristic Z provides a quick response to sudden current increases, especially important in applications requiring high selectivity. The three-pole design protects all three phases, providing comprehensive protection of the installation. Compact dimensions – only 3 modules wide – make it easy to install even in tight switchboards. The circuit breaker withstands impulse voltage up to 6kV, which increases its resistance to overvoltage. The possibility of connecting wires with a cross-section from 0.75 mm² to 25 mm² (multi-stranded) and from 0.75 mm² to 35 mm² (solid) provides flexibility in choosing wires. A wide range of ambient operating temperatures – from 0°C to 70°C – allows its use in various environmental conditions.

This circuit breaker meets the requirements of IEC 60947-2 and EN 60898 standards, confirming its safety and reliability. The degree of protection IP20 provides protection against accidental contact. Thanks to the possibility of additional equipment, it can be adapted to specific installation needs. Made of high-quality materials, it guarantees long-term and trouble-free operation, minimizing the risk of downtime and costly repairs.
