1SDA072213R1 ABB E1.2B 1600 Ekip Dip LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E1.2B 1600 Ekip Dip LSIG 3p WMP Air Circuit Breaker?

The ABB E1.2B 1600 Ekip Dip LSIG 3p WMP, order code 1SDA072213R1, is a withdrawable Emax 2 air circuit breaker (ACB) moving part designed for dependable protection, switching and isolation in low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 series, this three-pole unit combines a 1600 A rated uninterrupted current with the Ekip Dip LSIG electronic trip unit for comprehensive overload, short-circuit and ground-fault protection.

The compact E1.2B platform provides high-current circuit protection for industrial and commercial switchboards while helping optimise panel space. Its Ekip Dip LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection, allowing the breaker to respond effectively to sustained overloads, delayed and severe short circuits, and earth-fault conditions.

With a 1600 A rated uninterrupted current, a three-pole configuration, a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 42 kA across its principal low-voltage operating range, the E1.2B 1600 provides robust distribution protection. The WMP withdrawable moving-part configuration is designed for installation with the corresponding Emax 2 fixed part, supporting convenient isolation, testing and maintenance.

Comprehensive LSIG Protection for Power Distribution

The ABB Emax 2 E1.2B provides switching, isolation and protection for important high-current circuits within low-voltage electrical distribution systems. Its 1600 A current rating, 42 kA ultimate breaking capacity at 400–690 V AC and 42 kA short-time withstand capability for 1 s make it suitable for incoming supplies, distribution feeders and other applications requiring dependable fault interruption and selective coordination.

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 and maintainable solution for coordinated low-voltage power distribution.

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.
• High-current distribution circuits up to 1600 A.
• IT distribution networks up to 690 V.
• Withdrawable switchgear requiring convenient isolation and maintenance.
