Features & Benefits

• High current capacity: With 1250 A rated current, the breaker supports heavy duty feeders and large distribution systems.

• Robust fault interruption: 50 kA (at ~400 V) and up to 85 kA (at ~220-240 V) short-circuit breaking capacity delivers strong protection in fault events.

• Advanced electronic trip functionality: The EKIP DIP LS/I unit provides adjustable long-time, short-time and instantaneous trip settings, enabling higher selectivity and system protection flexibility.

• Four-pole design: Ensures all phases plus neutral are protected/disconnected — useful in installations with neutral current or full system isolation requirements.

• Front‐terminal fixed mounting: Front access wiring simplifies installation and servicing, and is space efficient within panel layouts.

• Reliable brand and construction: Part of ABB’s well-established protection equipment line, built for industrial performance and durability.

Applications / Use Cases

• Main distribution boards in industrial/commercial installations

• Protection of generator sets, transformer feeders, switchboards

• Critical power infrastructure (data centres, large HVAC systems, manufacturing plants)

• Upgrades of legacy systems requiring high-capacity MCCBs with electronic trip functionality

Ordering & Package Information
