Why Choose the ABB 1SDA072453R1 E4.2V 2000 Ekip Dip LSIG Air Circuit Breaker?
The ABB 1SDA072453R1 is a high-performance SACE Emax 2 E4.2V 2000 air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. This three-pole configuration combines a 2000 A rated current with an Ekip Dip LSIG solid-state electronic trip unit, providing comprehensive overload, short-circuit and ground-fault protection for industrial, commercial and infrastructure power systems.
As part of the advanced ABB SACE Emax 2 air circuit breaker series, the E4.2V is engineered for installations requiring very high short-circuit performance. The Ekip Dip LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions, helping protect electrical distribution equipment against a broad range of abnormal current conditions.
This model is a 3-pole withdrawable moving part (WMP) rated at 2000 A and 690 V AC. The E4.2V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC and 100 kA at 690 V AC, making it suitable for high-fault-level switchboards and critical power distribution installations.

High-Performance Protection for Critical Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 E4.2V provide switching and protection for high-current low-voltage distribution circuits. The electronic trip unit monitors circuit conditions and initiates interruption when configured protection thresholds are exceeded, helping protect switchgear, conductors and connected equipment against overload, short-circuit and ground-fault currents.
The Ekip Dip LSIG release combines long-time overload protection with short-time and instantaneous short-circuit protection and ground-fault protection. Together with the E4.2V frame's exceptionally high breaking capacity and withdrawable architecture, this makes the 1SDA072453R1 particularly suitable for demanding switchboards where fault-current capability, protection coordination and maintainability are critical.
Typical Applications
- Main incoming protection in high-current low-voltage switchboards.
- Industrial power distribution systems.
- Transformer and installation protection.
- High-fault-level feeder protection.
- Commercial and infrastructure electrical distribution.
- Power generation and critical power systems.
- Power distribution centres and large electrical installations.
