Why Choose the ABB S753DR-E100 Selective Main Circuit Breaker?
The ABB S753DR-E100 is a high-performance 3-pole selective main circuit breaker (SMCB) designed to provide reliable overload and short-circuit protection in low-voltage electrical distribution systems where selective coordination and continuity of supply are important. As part of the ABB S750 DR series, it provides robust main circuit protection for demanding three-phase power distribution applications.
The S753DR-E100 features an E selective tripping characteristic and is designed for coordinated operation with downstream protective devices. Its selective behaviour helps faults to be disconnected close to their source, reducing unnecessary interruption to unaffected circuits and supporting high availability within electrical installations.
With a rated current of 100 A, a 3-pole configuration and short-circuit breaking capacity of 25 kA, the S753DR-E100 is suitable for high-current three-phase distribution circuits requiring dependable selective protection. Its modular DIN-rail-mounted construction enables straightforward integration into distribution boards and electrical panel assemblies.

Reliable Selective Protection for Three-Phase Distribution
Selective main circuit breakers coordinate with downstream protective devices so that electrical faults can be disconnected as close as possible to their source. This helps maintain power to unaffected circuits, reduces the extent of an outage and improves availability throughout an electrical distribution system.
The ABB S750 DR series combines overload and short-circuit protection with selective coordination. The S753DR-E100 is therefore well suited to three-phase installations requiring a high-current main protective device together with effective coordination of downstream circuit protection.
