£761.46
The ABB S803HV-K4 is a high-performance three-pole miniature circuit breaker (MCB) designed to protect electrical circuits, cables and equipment against overload and short-circuit conditions. As part of the ABB S800HV high-performance circuit breaker range, it is engineered for demanding industrial applications requiring dependable overcurrent protection at high operating voltages.
This circuit breaker combines thermal overload protection with electromagnetic short-circuit protection, providing effective circuit protection within industrial electrical installations. The S800HV range is designed for high-voltage AC applications and features ABB's rapid arc-extinguishing technology to help interrupt fault currents safely and reliably.
With a rated current of 4 A, K tripping characteristic and three-pole configuration, the S803HV-K4 is suitable for protecting three-phase circuits and equipment with higher starting currents. This model is specified for applications up to 1000 V AC and has a 1.5 kA breaking capacity at 1000 V AC.
High-performance miniature circuit breakers such as the ABB S803HV-K4 protect electrical installations by automatically disconnecting a circuit when excessive current occurs. The thermal tripping mechanism provides protection against sustained overloads, while the electromagnetic mechanism responds rapidly to short-circuit conditions.
The ABB S800HV series is developed for demanding industrial installations where conventional low-voltage MCBs may not provide the required voltage capability. Its high-voltage design, rapid arc extinction and robust construction make the S803HV-K4 suitable for reliable protection in industrial power distribution, machinery and control systems.
