Overcurrent circuit breaker, 3P, B characteristic, 6A, 25kA, AC | S303P-B6 2CDS383001R0065

Electrical installation protection with ABB S303P-B6 circuit breaker

This three-pole circuit breaker from ABB's S300P series, with a rated current of 6A and B characteristic, provides reliable protection for your electrical installation. Designed to protect circuits against overload and short circuit, it ensures safe operation and long life of devices. The rated short-circuit breaking capacity of 25kA (at 400V) guarantees an effective response in emergency situations.

This circuit breaker is suitable for both domestic and commercial installations. Its compact dimensions – 3 modules wide – allow for easy mounting on a DIN rail in a distribution board. Designed to operate in temperatures from 0 to 70°C, it will perform well in various environmental conditions. The possibility of expanding with additional accessories increases its functionality and allows it to be adapted to individual needs.

• Fast response to overloads: B characteristic ensures quick tripping in case of overloads, protecting wires and devices from damage. This is especially important for circuits with receivers with high inrush current.
• High short-circuit breaking capacity: Short-circuit breaking capacity of 25kA (at 400V) and 100kA (according to IEC 60947-2) guarantees safe disconnection of the circuit in the event of a short circuit.
• Universal mounting: DIN rail mounting simplifies and speeds up installation, and compact dimensions save space in the distribution board.
• Wide range of wire cross-sections: The ability to connect solid wires with a cross-section from 0.75 to 35 mm² and stranded wires from 0.75 to 25 mm² provides flexibility in wire selection.
• Compliance with standards: The circuit breaker meets the requirements of standards such as CSA 22.2 No. 235, IEC EN 60898-1, IEC EN 60947-2 and UL 1077, which confirms its safety and reliability.

This circuit breaker is made of high-quality materials, which guarantees its durability and resistance to mechanical damage. The IP20 degree of protection provides protection against accidental contact. The rated voltage of 415V AC and the insulation voltage Ui of 500V ensure safe operation in standard electrical installations. Power losses of only 3W minimize the impact on the energy efficiency of the system.
