The ABB S203-Z2NA 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 sensitive industrial, commercial and OEM electrical installations. Featuring a Z tripping characteristic, this breaker is specifically designed for circuits requiring extremely fast magnetic tripping, making it ideal for protecting semiconductor devices, PLCs, instrumentation and other sensitive electronic equipment.
Manufactured using ABB's advanced thermal and electromagnetic trip technology, the S203-Z2NA delivers reliable circuit protection with excellent current limiting performance. Its compact DIN rail mounted design enables quick installation within switchboards, distribution boards and industrial control panels while remaining fully compatible with ABB's comprehensive range of S200 accessories.
With a 2 A rated current, 3P+N configuration and a 6 kA breaking capacity, the ABB S203-Z2NA provides dependable protection for three-phase electrical systems requiring a switched neutral, particularly where sensitive electronic equipment requires rapid fault clearance.
The ABB S203-Z2NA automatically disconnects electrical circuits during overload and short circuit conditions, helping protect wiring, control equipment and sensitive electronic devices from damage while maintaining system reliability.
Its Z characteristic provides a very fast magnetic trip response, making it particularly suitable for semiconductor protection, PLC systems, instrumentation, electronic controls and other applications where even relatively small fault currents must be cleared rapidly.
