1SDA072702R1 ABB E1.2N 630 Ekip Dip LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E1.2N 630 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E1.2N 630 Ekip Dip LSI 4p WMP, order code 1SDA072702R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for protection and switching in low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 E1.2 series, it combines a 630 A rated current with an electronic Ekip Dip LSI protection trip unit for dependable overload and short-circuit protection.

The Ekip Dip LSI electronic trip unit provides long-time, short-time and instantaneous protection functions, supporting effective protection and selectivity in industrial and commercial electrical distribution systems. Its electronic protection technology provides accurate circuit monitoring and tripping while allowing protection settings to be matched to the requirements of the installation.

Designed as the moving part of a withdrawable Emax 2 circuit breaker installation, the E1.2N 630 can be removed from its fixed chassis for inspection, maintenance or replacement. The four-pole configuration enables switching and protection of all four conductors in suitable three-phase distribution systems, while the N performance level provides robust short-circuit breaking capability for demanding installations.

Advanced Protection for Low-Voltage Distribution

ABB SACE Emax 2 air circuit breakers are designed to protect low-voltage electrical distribution systems against overloads and short circuits while providing reliable switching and isolation. The Ekip Dip electronic trip unit uses dedicated protection functions to detect abnormal current conditions and initiate circuit breaker operation when required.

The withdrawable E1.2 construction is particularly useful in critical distribution equipment where maintainability and continuity of service are important. The moving breaker can be separated from the corresponding fixed part, allowing maintenance and servicing while supporting modular switchboard construction.
