1SDA072062R1 ABB E1.2C 630 Ekip Dip LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E1.2C 630 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E1.2C 630 Ekip Dip LSI 3p WMP, order code 1SDA072062R1, is a high-performance three-pole air circuit breaker moving part designed for reliable protection and control of low-voltage electrical distribution systems. As part of the advanced ABB SACE Emax 2 air circuit breaker series, it combines robust switching performance with an Ekip Dip LSI electronic trip unit for comprehensive overload and short-circuit protection.

Designed for withdrawable installations, the E1.2C provides a practical solution for industrial switchboards and power distribution equipment where reliability, maintainability and electrical protection are essential. The Emax 2 platform is engineered for modern low-voltage distribution systems, while the withdrawable moving-part configuration facilitates inspection, servicing and replacement within compatible switchgear assemblies.

With a rated uninterrupted current of 630 A, a rated ultimate short-circuit breaking capacity of 50 kA at 440 V AC and a short-time withstand current of 42 kA for 1 s, the E1.2C 630 provides robust protection for demanding distribution applications. Its Ekip Dip LSI release provides long-time, short-time and instantaneous protection functions for greater selectivity and control within electrical networks.

Reliable and Selective Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect low-voltage electrical networks against excessive currents caused by overloads and short circuits. By safely interrupting fault currents, the breaker helps protect switchgear, conductors and connected equipment while supporting continuity and reliability throughout the electrical distribution system.

The Ekip Dip LSI trip unit adds short-time protection to the long-time and instantaneous functions, enabling improved coordination and selectivity between protective devices within a distribution network. This makes the 1SDA072062R1 particularly suitable for systems where controlled fault-clearing times and coordination between upstream and downstream circuit breakers are important.
