£25,556.65
The ABB 1SDA124953R1 is a high-capacity low-voltage air circuit breaker designed for reliable protection, switching and monitoring in demanding electrical distribution systems. Part of the advanced ABB SACE Emax 3 E6.3 range, this three-pole fixed circuit breaker combines a 5000 A rated current with an Ekip Aware LSI electronic protection release.
The E6.3H configuration is designed for high-performance power distribution applications where dependable circuit protection and sophisticated electronic monitoring are required. Its Ekip Aware release provides long-time, short-time and instantaneous (LSI) protection functions, helping protect electrical installations against different overcurrent conditions.
With a 5000 A rated current, three-pole configuration and fixed mounting arrangement, the ABB 1SDA124953R1 is suited to high-current switchboards, main distribution systems and industrial electrical installations. The FHR configuration provides a fixed breaker with horizontal rear connection orientation.
The ABB Emax 3 E6.3 platform is designed for high-current electrical distribution applications, with the E6.3 family covering ratings up to 6300 A. The E6.3H version provides a high-performance solution for installations where substantial current-carrying capacity and dependable circuit protection are required.
The integrated Ekip Aware LSI release combines electronic protection functions with advanced monitoring capabilities. Long-time protection helps address sustained overload conditions, short-time protection responds to higher fault currents with controlled timing, while instantaneous protection provides rapid operation for severe fault conditions.
The fixed FHR configuration is intended for permanent installation within compatible switchboards and distribution assemblies. Its horizontal rear connection arrangement can simplify conductor and busbar integration where the switchboard design requires this connection orientation.
