Why Choose the ABB E1.2N 800 Ekip Dip LSIG 3P F F Air Circuit Breaker?
The ABB E1.2N 800 Ekip Dip LSIG 3P F F, order code 1SDA070763R1, is an 800 A three-pole fixed air circuit breaker from the ABB SACE Emax 2 range. It combines the compact E1.2 frame with an Ekip Dip LSIG solid-state electronic trip unit, providing comprehensive overload, selective short-circuit, instantaneous short-circuit and ground-fault protection for low-voltage AC distribution systems.
The E1.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 400–440 V AC and 50 kA at 500–690 V AC. The breaker also provides a rated short-time withstand current of 50 kA for 1 s, supporting demanding distribution applications where both fault interruption and selective coordination are important.
Rated at 800 A with an operational voltage up to 690 V AC, this model uses a fixed three-pole construction with front bolt terminals. ABB specifies the complete breaker with four auxiliary contacts and open/closed breaker position indication, making it suitable for main distribution, feeder and industrial switchboard applications requiring integrated LSIG protection.

Comprehensive LSIG Protection for Low-Voltage Distribution
The Ekip Dip LSIG release combines four principal protection functions. Long-time protection responds to sustained overload currents, short-time selective protection enables controlled response to short-circuit conditions, instantaneous protection provides rapid interruption of severe faults, and ground-fault protection detects fault current flowing to earth.
Combined with the E1.2N frame's 66 kA ultimate breaking capacity at 400–440 V AC and 50 kA short-time withstand current for 1 s, the 1SDA070763R1 provides a robust solution for demanding distribution networks. Its 800 A rating, fixed construction and front terminals make it particularly suitable for permanent installation in industrial, commercial and infrastructure switchboards.
Typical Applications
- Low-voltage main distribution switchboards.
