ABB 1SDA071428R1 Emax 2 E1.2C 1000 four-pole fixed air circuit breaker with a 1000 A rating, Ekip Hi-Touch LSI electronic protection, front terminals and 50 kA ultimate breaking capacity at 400–440 V AC.
£7,704.17
The ABB E1.2C 1000 Ekip Hi-Touch LSI 4p F F, order code 1SDA071428R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, switching and advanced monitoring in low-voltage electrical distribution systems. Combining the compact E1.2 frame with an Ekip Hi-Touch LSI electronic trip unit, it provides configurable protection for demanding industrial, commercial and infrastructure power networks.
This fixed circuit breaker features front terminals and an Ekip Hi-Touch LSI electronic release, providing long-time overload, selective short-time short-circuit and instantaneous short-circuit protection. The Hi-Touch platform also supports advanced electrical measurement and network analysis, helping operators monitor distribution-system performance as well as protect critical circuits.
With a rated uninterrupted current of 1000 A, a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 50 kA at 400–440 V AC, the E1.2C 1000 delivers robust protection for substantial electrical loads. Its four-pole configuration, fixed construction and front connections make it particularly suitable for permanent installation in modern low-voltage switchboards.
The ABB SACE Emax 2 E1.2C combines substantial current capacity with high short-circuit performance in a compact air circuit breaker platform. Its 50 kA breaking capacity at 400–440 V AC and short-time withstand capability of 42 kA for 1 s make it suitable for main incomers, feeders and other critical circuits where both fault interruption and selective coordination are important.
The Ekip Hi-Touch LSI trip unit combines long-time, selective short-time and instantaneous protection with advanced monitoring capabilities. Network Analyzer functionality can support real-time assessment of power quality, while the Ekip platform can be integrated with compatible communication and energy-management architectures, making the breaker well suited to modern intelligent low-voltage distribution systems.
