£17,219.09
The ABB 1SDA072480R1 is a high-performance SACE Emax 2 E4.2V 2500 air circuit breaker moving part designed for advanced protection of demanding low-voltage power distribution and generator systems. Configured as an E4.2V 2500 Ekip G Hi-Touch LSIG 3p WMP, it combines a 2500 A rated current, three-pole construction and ABB's advanced Ekip G Hi-Touch electronic trip unit with comprehensive LSIG protection.
As part of the ABB SACE Emax 2 air circuit breaker series, the E4.2V platform is engineered for electrical networks with exceptionally high prospective fault currents. The V performance level provides an ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, while the E4.2V 2500 platform provides a rated short-time withstand current of 100 kA for 1 s, supporting demanding selective distribution architectures.
The Ekip G Hi-Touch LSIG trip unit combines advanced long-time, short-time, instantaneous and earth-fault protection with generator-oriented protection, measurement and monitoring functionality. Its three-pole withdrawable moving-part (WMP) configuration is designed for use with the appropriate Emax 2 fixed part, supporting isolation, inspection and maintenance in critical switchboard installations.
Air circuit breakers such as the ABB Emax 2 E4.2V protect high-current low-voltage networks by detecting abnormal electrical conditions and interrupting potentially damaging fault currents. The E4.2V platform combines substantial continuous-current capability with exceptional short-circuit performance, making it particularly suitable for critical distribution points where fault levels and continuity requirements are demanding.
The Ekip G Hi-Touch LSIG trip unit extends this capability with sophisticated electronic protection for power distribution and generator applications. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection rapidly clears severe short circuits and earth-fault protection detects potentially hazardous current paths to earth.
