ABB 1SDA128931R1 SACE Emax 3 E1.3C 1250 three-pole air circuit breaker with Ekip Aware LSIG trip unit, 1250 A rating, 50 kA Icu at 415 V and withdrawable moving part configuration.
£3,555.19
The ABB 1SDA128931R1 is a high-performance SACE Emax 3 E1.3C air circuit breaker designed for reliable protection and control of low-voltage electrical distribution systems. This three-pole circuit breaker is rated at 1250 A and is equipped with an Ekip Aware LSIG trip unit providing comprehensive electronic protection functions for demanding power distribution applications.
As part of the ABB SACE Emax 3 range, the E1.3C platform combines advanced electronic protection and monitoring capabilities with the robust construction expected from a modern air circuit breaker. The Ekip Aware LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection functions for electrical distribution systems.
The 1SDA128931R1 is supplied as the moving part only (WMP) of a withdrawable circuit breaker. Its three-pole configuration has a rated current of 1250 A and a rated ultimate short-circuit breaking capacity of 50 kA at 415 V. The corresponding fixed part is ordered separately, allowing the withdrawable breaker arrangement to be configured for the intended switchgear installation.
Air circuit breakers such as the ABB SACE Emax 3 E1.3C provide dependable protection for electrical distribution systems by interrupting fault currents and protecting conductors and connected equipment from damaging overcurrent conditions. The E1.3C configuration is designed for applications requiring a high current rating and substantial short-circuit interruption capability.
The integrated Ekip Aware LSIG trip unit provides electronic protection and monitoring functionality. Its LSIG configuration combines long-time, short-time, instantaneous and earth-fault protection functions, helping provide comprehensive protection for modern low-voltage distribution systems.
The withdrawable construction allows the circuit-breaker moving part to be withdrawn from its separately ordered fixed part. This arrangement can support inspection, maintenance and replacement procedures in compatible switchgear installations.
