ABB 1SDA072279R1 is a SACE Emax 2 E2.2N 1000 A three-pole withdrawable air circuit breaker with an Ekip Hi-Touch LSIG electronic trip unit for advanced overload, short-circuit and earth-fault protection.
£7,761.75
The ABB 1SDA072279R1 is a high-performance SACE Emax 2 E2.2N air circuit breaker designed for advanced protection and switching in demanding low-voltage electrical distribution systems. This three-pole withdrawable moving-part configuration has a rated uninterrupted current of 1000 A and incorporates the advanced Ekip Hi-Touch LSIG electronic trip unit.
As part of the ABB SACE Emax 2 range, the E2.2N combines high breaking performance with sophisticated electronic protection for industrial, commercial and infrastructure switchboards. The Ekip Hi-Touch LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection, giving engineers comprehensive protection and advanced monitoring capabilities for critical electrical distribution circuits.
The E2.2N 1000 provides a rated ultimate short-circuit breaking capacity of 66 kA at 415 V AC and maintains a 66 kA breaking capacity at 690 V AC. Its withdrawable construction is supplied with four auxiliary contacts and a trip signalling contact, while the compatible fixed part is ordered separately, making this configuration well suited to maintainable switchboard installations.
Air circuit breakers such as the ABB Emax 2 E2.2N provide essential switching and fault protection for high-current low-voltage networks. The Ekip Hi-Touch LSIG electronic release provides coordinated long-time overload, short-time and instantaneous short-circuit protection together with earth-fault protection, helping isolate abnormal conditions while supporting selective protection strategies across complex electrical distribution systems.
The E2.2N platform combines a strong 66 kA breaking capability with a maintainable withdrawable architecture. The moving breaker assembly can be removed from its compatible fixed part for servicing or replacement, making the 1SDA072279R1 particularly suitable for switchboards where protection performance, system availability and maintainability are important.
