£167.81
The ABB S203M-C16NA (Part Number 2CDS273103R0164) is a high-performance 3P+N miniature circuit breaker (MCB) from the trusted ABB System pro M compact S200M range. Designed for residential, commercial and industrial electrical installations, it provides dependable protection against overloads and short circuits.
This ABB miniature circuit breaker is current limiting and uses two separate tripping mechanisms: a delayed thermal trip for overload protection and an electromechanical trip for short circuit protection. Its compact DIN rail mounted design makes it suitable for distribution boards, switchgear assemblies and industrial control panels.
With a 16 A rated current, Type C tripping characteristic, 3P+N configuration and 10 kA breaking capacity, the S203M-C16NA is ideal for circuits with moderate inrush currents, including motors, lighting systems, control equipment and general industrial loads.
The ABB S203M-C16NA protects electrical circuits by disconnecting the supply when overload or short circuit conditions occur. The delayed thermal mechanism responds to sustained overloads, while the electromechanical trip provides fast interruption during short circuit fault conditions.
Type C miniature circuit breakers are designed for applications where moderate starting currents are expected. This makes the S203M-C16NA suitable for motor circuits, transformer-fed loads, control panels and industrial equipment where dependable protection and operational continuity are important.
