Why Choose the ABB S203M-C16NA Miniature Circuit Breaker?
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.
