1SDA072612R1 ABB E6.2H 5000 Ekip Dip LSI 3-Pole Air Circuit Breaker

Why Choose the ABB 1SDA072612R1 E6.2H 5000 Ekip Dip LSI Air Circuit Breaker?

The ABB 1SDA072612R1 is a high-performance SACE Emax 2 E6.2H 5000 air circuit breaker moving part designed for demanding high-current low-voltage power distribution systems. This three-pole configuration combines a 5000 A rated uninterrupted current with an Ekip Dip LSI electronic trip unit, providing long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection.

As part of the ABB SACE Emax 2 range, the E6.2H is engineered for installations requiring substantial current capacity, high short-circuit performance and selective protection. The Ekip Dip LSI release provides adjustable electronic protection for overload and short-circuit conditions, making this breaker suitable for main incomers, high-current feeders and other critical distribution circuits.

This model is a 3-pole withdrawable moving part (WMP) rated at 5000 A and 690 V AC. The E6.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 415 V AC and 100 kA at 690 V AC, supporting demanding switchboards with high prospective fault currents.
