1SDA071261R1 ABB E6.2H 5000 Ekip Dip LI 3p FHR Air Circuit Breaker

Why Choose the ABB E6.2H 5000 Ekip Dip LI 3p FHR Air Circuit Breaker?

The ABB E6.2H 5000 Ekip Dip LI 3p FHR, order code 1SDA071261R1, is a high-current SACE Emax 2 air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power distribution systems. Rated at 5000 A, this three-pole fixed circuit breaker combines ABB's E6.2H frame with an Ekip Dip LI solid-state electronic trip unit.

The Ekip Dip LI release provides long-time overload (L) and instantaneous short-circuit (I) protection. This LI configuration provides straightforward electronic overcurrent protection for major incomers and high-current feeders where long-time and instantaneous protection functions are required without integrated short-time or earth-fault protection.

The 1SDA071261R1 is supplied as a fixed three-pole breaker with rear horizontal (HR) terminals, four auxiliary contacts and circuit-breaker open/closed position indication. With a rated operational voltage of 690 V AC and a short-circuit breaking capacity of 100 kA at 400 V AC, it is engineered for substantial industrial, infrastructure and critical power distribution installations.

High-Current LI Protection for Major Power Distribution Systems

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and fault protection for high-current low-voltage electrical networks. The E6.2H frame combines a substantial 5000 A current rating with 100 kA short-circuit breaking capacity at 400 V AC, making the 1SDA071261R1 suitable for major main incomers, transformer secondary circuits and other high-current distribution feeders.

The Ekip Dip LI trip unit provides electronic long-time overload and instantaneous short-circuit protection. Long-time protection responds to sustained overcurrent conditions that could otherwise cause excessive thermal stress, while instantaneous protection provides rapid operation during severe short-circuit faults, helping protect conductors, switchgear and connected equipment within a correctly coordinated electrical system.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main incomer and 5000 A feeder protection.
• Transformer secondary distribution systems.
• Generator-fed low-voltage distribution systems.
• Manufacturing and process-industry electrical installations.
• Large commercial and infrastructure power distribution.
• Data centres and critical electrical infrastructure.
• Installations requiring high-current LI electronic protection and substantial short-circuit interruption capability.
