£177.88
The ABB S303P-C32NA, product code 2CDS383103R0324, is a high-performance miniature circuit breaker (MCB) designed to protect demanding industrial electrical installations against overloads and short circuits. As part of the robust ABB System pro M compact S300P series, it delivers dependable circuit protection, high breaking capacity and reliable operation in distribution boards, machinery and control-panel applications.
This miniature circuit breaker uses a thermal tripping mechanism to provide overload protection and an electromagnetic mechanism for rapid short-circuit protection. Its Type C tripping characteristic allows it to accommodate moderate inrush currents, making it suitable for circuits supplying motors, transformers, fluorescent lighting, control equipment and other inductive electrical loads.
With a rated current of 32 A, a 3P+N configuration and a rated operational voltage of 415 V AC, the S303P-C32NA is ideal for three-phase electrical systems requiring simultaneous neutral switching. Its high breaking capacity of 25 kA at 415 V AC, compact DIN rail format and compatibility with ABB modular accessories support safe, flexible and efficient panel construction.
Miniature circuit breakers automatically disconnect an electrical circuit when an overload or short circuit is detected. The thermal release responds to prolonged overcurrent conditions, while the electromagnetic release provides rapid isolation during high fault currents, helping protect cables, machinery and connected electrical equipment.
The Type C characteristic of the ABB S303P-C32NA is suited to circuits with moderate starting currents. Combined with its high short-circuit breaking capacity and 3P+N configuration, the breaker provides dependable protection for three-phase industrial distribution systems where neutral isolation is also required.
