ABB S301P-Z63NA miniature circuit breaker with a 63 A rated current, Z tripping characteristic and 1P+N configuration for industrial overload and short-circuit protection.
£136.01
The ABB 2CDS381103R0608, also identified as the S301P-Z63NA, is a high-performance miniature circuit breaker (MCB) designed to protect industrial electrical installations against overloads and short circuits. As part of the advanced ABB System pro M compact S300P series, it provides dependable circuit protection for applications where rapid fault disconnection and high breaking capacity are required.
This circuit breaker combines a compact modular design with robust electrical performance, making it suitable for distribution boards, control panels and machinery installations. Its Z tripping characteristic provides fast magnetic operation, helping protect sensitive electronic equipment and circuits with low permissible fault currents.
With a rated current of 63 A, a 240 V AC rated voltage and a 1P+N configuration, the S301P-Z63NA delivers reliable protection while simultaneously switching the neutral conductor. Its DIN rail mounting format, fail-safe terminals and integrated trip indication support efficient installation, inspection and maintenance.
Miniature circuit breakers automatically disconnect a circuit when excessive current is detected. This protects electrical conductors and connected equipment from overheating, insulation damage and potentially hazardous short-circuit conditions.
The Z tripping characteristic is designed to operate rapidly at comparatively low fault-current multiples. This makes the ABB S301P-Z63NA particularly suitable for electronic equipment, semiconductor devices, control circuits and other sensitive loads that require faster magnetic protection than conventional B, C or D characteristic breakers.

This miniature circuit breaker protects industrial electrical circuits against overloads and short circuits, particularly where sensitive equipment requires rapid fault disconnection.
The ABB S301P-Z63NA has a rated current of 63 A.
A Z characteristic provides rapid magnetic tripping at relatively low fault-current levels, making the breaker suitable for sensitive electronic equipment and control circuits.
The 1P+N configuration protects the phase conductor while simultaneously switching the neutral conductor when the circuit breaker operates.
The circuit breaker is designed for installation on a standard DIN rail inside an electrical distribution board, control panel or machinery enclosure.
ABB System pro M compact S300P miniature circuit breakers are used by electrical engineers, panel builders and industrial automation specialists to provide reliable overload and short-circuit protection in demanding electrical installations.
