£213.67
The ABB S203-Z1NA is a premium 3P+N miniature circuit breaker (MCB) from the trusted ABB System pro M Compact S200 series, engineered to provide dependable overload and short circuit protection for specialised industrial and commercial electrical installations. Featuring a Z tripping characteristic, this circuit breaker is specifically designed to protect highly sensitive electronic circuits and semiconductor equipment where rapid fault disconnection is essential.
Built using ABB's proven thermal and electromagnetic trip technology, the S203-Z1NA delivers reliable circuit protection while maintaining excellent current limiting performance. Its compact DIN rail mounted design simplifies installation within control panels, switchboards and OEM machinery.
With a 1 A rated current, 3P+N configuration and a 6 kA breaking capacity, the ABB S203-Z1NA is ideal for protecting sensitive control circuits, instrumentation, PLC systems and electronic equipment requiring very fast magnetic tripping characteristics.
The ABB S203-Z1NA automatically disconnects the electrical supply when overload or short circuit conditions occur, helping protect wiring, equipment and connected devices from damage. Its current limiting design reduces fault energy, improving the protection of downstream equipment.
The Z characteristic is intended for circuits with very low inrush currents and is commonly specified for semiconductor devices, electronic control systems, instrumentation and PLC equipment where fast fault response is essential.
