£106.41
The ABB S303P-B10 (Product ID: 2CDS383001R0105) is a premium 3-pole miniature circuit breaker (MCB) engineered to provide reliable overload and short-circuit protection for industrial electrical installations. As part of the proven ABB System pro M compact S300P series, it is manufactured in accordance with international IEC and UL standards, making it suitable for industrial control panels, OEM machinery and commercial distribution systems.
Designed for dependable long-term operation, the S303P-B10 incorporates ABB's advanced thermal and magnetic protection technology within a compact DIN rail mounted enclosure. Its B tripping characteristic provides fast operation at relatively low overcurrents, making it ideal for protecting resistive loads, control circuits, instrumentation, lighting installations and sensitive electrical equipment.
Featuring a 10 A rated current, 3-pole configuration and a 25 kA short-circuit breaking capacity, the S303P-B10 delivers dependable protection where high fault levels and reliable circuit isolation are required.
Miniature circuit breakers automatically disconnect electrical circuits when overload or short-circuit conditions occur, protecting wiring, equipment and connected devices from damage. The ABB S300P range is specifically designed for industrial environments requiring dependable protection, high reliability and compliance with international standards.
The B tripping characteristic is particularly suited to resistive loads and circuits with low inrush currents, providing rapid fault clearance while helping to protect sensitive equipment and electrical installations.
