ABB S402P-B16 is a 16 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.
£48.52
The ABB S402P-B16 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 current-limiting circuit protection with a flexible plug-in architecture for efficient installation in commercial, industrial and critical-power applications.
This MCB features a Type B tripping characteristic and a rated current of 16 A. The S400P design provides thermal protection against sustained overloads and electromagnetic protection against short-circuit faults, helping protect cables, conductors and connected electrical circuits.
With a rated voltage of 240 V AC and an ultimate short-circuit breaking capacity of 40 kA at 230 V and 400 V, the S402P-B16 provides high fault-current performance in a compact two-module format. Its SMISSLINE TP plug-in connection enables direct integration with the compatible socket system, supporting efficient installation, servicing and future distribution-system modifications.
Miniature circuit breakers such as the ABB S402P-B16 protect electrical cables and circuits against overload and short-circuit currents. A delayed thermal tripping mechanism responds to sustained overload conditions, while an electromagnetic tripping mechanism provides rapid disconnection during short-circuit faults.
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.
