Why Choose the ABB E1.2B 1000 Ekip Dip LSI 4p F F Air Circuit Breaker?
The ABB E1.2B 1000 Ekip Dip LSI 4p F F, order code 1SDA071412R1, is a compact and dependable four-pole air circuit breaker (ACB) designed for protection and switching in low-voltage electrical distribution systems. As part of the ABB SACE Emax 2 series, it combines the E1.2 frame with an Ekip Dip LSI electronic trip unit to provide configurable protection for industrial, commercial and infrastructure power networks.
This fixed circuit breaker features front terminals and an Ekip Dip LSI electronic protection release, providing long-time overload, selective short-time short-circuit and instantaneous short-circuit protection. The LSI protection functions support effective coordination between upstream and downstream devices, helping isolate electrical faults while maintaining continuity elsewhere in the distribution system.
With a rated uninterrupted current of 1000 A and an ultimate short-circuit breaking capacity of 42 kA at 440 V AC, the E1.2B 1000 provides reliable protection for substantial low-voltage loads. Its four-pole configuration enables switching across three phases and neutral, while its fixed construction and front connections make it suitable for permanent installation within electrical switchboards.
