1SDA072133R1 ABB E1.2B 1000 Ekip Dip LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E1.2B 1000 Ekip Dip LSIG 3p WMP Air Circuit Breaker?

The ABB E1.2B 1000 Ekip Dip LSIG 3p WMP, order code 1SDA072133R1, is a withdrawable Emax 2 air circuit breaker (ACB) designed for dependable protection and switching in low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, this three-pole moving part combines a 1000 A rated uninterrupted current with an Ekip Dip LSIG electronic trip unit for comprehensive overload, short-circuit and ground-fault protection.

The compact E1.2B platform is engineered for industrial and commercial switchboards where reliable fault interruption and efficient use of panel space are important. Its Ekip Dip LSIG solid-state release provides long-time, short-time, instantaneous and ground-fault protection functions, allowing the breaker to protect against sustained overloads, short circuits and earth faults while supporting coordinated protection within the electrical network.

With a rated uninterrupted current of 1000 A, a three-pole configuration, an ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, the E1.2B 1000 is suited to demanding distribution applications. The WMP withdrawable moving-part configuration is designed for installation with the corresponding Emax 2 fixed part, supporting convenient isolation, inspection and maintenance.

Comprehensive LSIG Protection for Power Distribution

Air circuit breakers such as the ABB Emax 2 E1.2B provide switching, isolation and protection for important circuits within low-voltage electrical distribution systems. The combination of a 1000 A current rating, 42 kA short-circuit breaking capability and 42 kA short-time withstand performance makes this model suitable for incoming supplies, distribution feeders and other applications where dependable fault interruption and system coordination are required.

The Ekip Dip LSIG trip unit provides four fundamental electronic protection functions. Long-time protection responds to sustained overloads, short-time protection enables delayed fault clearing and improved selectivity, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection responds to earth-fault conditions. Combined with the withdrawable Emax 2 construction, these functions provide a practical solution for maintainable and coordinated low-voltage switchboards.

Typical Applications

• Low-voltage distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Incoming and outgoing feeder protection.
• Selective and coordinated distribution networks.
• Manufacturing and production facilities.
• Infrastructure and process installations.
• Systems requiring integrated ground-fault protection.
• Withdrawable switchgear requiring convenient isolation and maintenance.
