Comprehensive LSIG Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect low-voltage electrical networks against overloads, short circuits and ground faults while providing dependable switching and isolation of high-current circuits. The E2.2S platform combines high fault-interruption capability with 66 kA short-time withstand performance, supporting selective protection in demanding power distribution systems.

The Ekip Dip LSIG release combines adjustable long-time, selective short-time, instantaneous and ground-fault protection. These functions help coordinate upstream and downstream protective devices, allowing electrical faults to be isolated close to their source while reducing unnecessary interruption to unaffected sections of an installation.

Typical Applications

• Main low-voltage switchboards and distribution boards.
• Industrial power distribution systems.
• Commercial buildings and infrastructure installations.
• Manufacturing plants and process facilities.
• Transformer secondary and main incoming protection.
• High-current feeders requiring selective short-circuit and integrated ground-fault protection.
