ABB S402P-B4 is a 4 A Type B 2-pole miniature circuit breaker rated at 240 V AC with 40 kA ultimate short-circuit breaking capacity for the SMISSLINE TP plug-in system.
£73.07
The ABB S402P-B4 is a high-performance 2-pole miniature circuit breaker (MCB) designed for reliable overload and short-circuit protection in low-voltage electrical distribution systems. As part of the ABB S400P range for the SMISSLINE TP plug-in system, it combines dependable circuit protection with a flexible plug-in architecture for commercial and industrial installations.
This MCB features a Type B tripping characteristic and a rated current of 4 A, making it suitable for circuits with relatively low starting currents. The S400P range protects cables and conductors against overload and short-circuit conditions, while its plug-in format supports efficient installation and modification within compatible SMISSLINE TP distribution systems.
With a rated operating voltage of 240 V AC and an ultimate short-circuit breaking capacity of 40 kA at 230 V and 400 V, the S402P-B4 provides high fault-current performance in a compact 2-pole device. ABB order code 2CCG000499R0001 identifies this specific 4 A Type B version of the S402P range.
Miniature circuit breakers such as the ABB S402P-B4 protect electrical cables and circuits against overload and short-circuit currents. Its Type B characteristic is suited to circuits with comparatively low inrush currents, while the high short-circuit breaking capacity provides robust protection where substantial prospective fault currents may occur.
The ABB SMISSLINE TP system uses a plug-in distribution architecture that allows compatible protective devices to connect directly to the socket system. This approach supports flexible electrical distribution designs while helping simplify installation, servicing and future modifications within control panels and distribution assemblies.
