Why Choose the ABB S801S-D4 High Performance MCB?
The ABB S801S-D4 is a high-performance single-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical distribution systems. As part of the ABB S800S high-performance MCB series, it combines compact modular construction with high interruption capability for commercial and industrial installations.
This circuit breaker features a Type D tripping characteristic, making it particularly suitable for circuits supplying equipment with high starting or inrush currents, including motors, transformers and other inductive loads. Separate thermal and electromagnetic tripping mechanisms provide dependable protection against sustained overloads and short-circuit faults.
With a rated current of 4 A, a single-pole configuration and a rated ultimate short-circuit breaking capacity of up to 50 kA at 240 V AC, the S801S-D4 is engineered for applications requiring robust circuit protection and high fault interruption performance. Its interchangeable cage terminal supports secure and practical installation within electrical distribution equipment.
