£219.61
The ABB S303P-Z1.6 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect sensitive electrical circuits against overloads and short circuits. Part of the established ABB System pro M compact S300P series, it provides precise and dependable protection for industrial, commercial and OEM electrical installations.
Manufactured in accordance with international IEC and UL standards, the S303P-Z1.6 combines robust construction with a compact modular design. Its standard DIN rail mounting allows straightforward installation inside distribution boards, switchboards and industrial control panels, while fail-safe terminals help reduce the risk of incorrect conductor connection.
Featuring a 1.6 A rated current, a sensitive Z curve tripping characteristic and a 25 kA breaking capacity, this miniature circuit breaker is particularly suitable for electronic equipment, semiconductor devices, instrumentation and control circuits requiring rapid protection against relatively low overcurrents.
The ABB S303P-Z1.6 automatically disconnects the electrical supply when an overload or short circuit occurs, helping protect conductors, control devices and connected equipment from damage. Its Z curve characteristic provides magnetic tripping at lower overcurrent levels than B, C, D or K curve circuit breakers.
This sensitive operating characteristic makes the S303P-Z1.6 particularly suitable for electronic components, semiconductor equipment and industrial control systems that may be damaged by comparatively small overcurrents. Its high breaking capacity also supports reliable operation in installations with elevated prospective fault currents.
