Why Choose the ABB S804S-D8 High Performance MCB?
The ABB S804S-D8 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial electrical systems. As part of the ABB S800S high-performance circuit breaker range, it combines a rated current of 8 A, D tripping characteristic and a maximum breaking capacity of 50 kA for installations requiring robust fault protection.
The S804S-D8 is a current-limiting circuit breaker using two complementary tripping mechanisms: a thermal release for overload protection and an electromagnetic release for rapid short-circuit protection. Its D characteristic is suitable for circuits with elevated starting and inrush currents, including appropriate motors, transformers and industrial equipment.
With a four-pole configuration, 8 A rated current and maximum breaking capacity of 50 kA at 240/415 V AC, the S804S-D8 provides dependable protection for demanding distribution systems. It can be used at voltages up to 400/690 V AC and in suitable DC applications, while interchangeable cage terminals support secure and practical installation.
