1SDA071265R1 ABB E6.2H 5000 Ekip Touch LSI 3p FHR Air Circuit Breaker

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

The ABB E6.2H 5000 Ekip Touch LSI 3p FHR, order code 1SDA071265R1, is a high-capacity air circuit breaker (ACB) designed for protection, switching and isolation in demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 range, it combines a 5000 A rated uninterrupted current with the Ekip Touch LSI solid-state electronic trip unit for major industrial, infrastructure and critical-power installations.

The E6.2H performance level provides substantial short-circuit capability, with a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC. Its Ekip Touch LSI electronic release provides long-time overload, selective short-time and instantaneous short-circuit protection, supporting coordinated protection across high-current electrical distribution networks.

With a rated voltage of 690 V, three-pole construction and fixed installation with rear horizontal terminals, the 1SDA071265R1 is engineered for integration into high-capacity low-voltage switchboards and power distribution assemblies. Its combination of a 5000 A current rating, adjustable LSI protection and Emax 2 technology makes it particularly suitable for major incomers, bus couplers and feeders where dependable protection and selectivity are important.

Selective LSI Protection for High-Current Power Distribution

The ABB SACE Emax 2 E6.2H is engineered for large low-voltage electrical networks where substantial continuous-current capability and high short-circuit performance are required. Its 5000 A current rating and 100 kA breaking capacity make it suitable for protecting major switchboards, busbars, transformers, feeders and other critical components within high-capacity power distribution systems.

The Ekip Touch LSI electronic trip unit combines long-time overload, selective short-time and instantaneous short-circuit protection. The adjustable short-time function helps coordinate upstream and downstream protective devices so that the protective device closest to a fault can operate first where the system design permits. This LSI configuration is particularly suitable where selective overcurrent protection is required without integrated earth-fault protection.

Typical Applications

• Main incomer protection in high-capacity low-voltage switchboards.
• Industrial power distribution systems.
• Transformer secondary protection.
• High-current bus-coupler applications.
• Data centres and critical-power facilities.
• Large commercial and infrastructure electrical installations.
• Manufacturing and heavy-process plants.
• High-current feeders requiring selective LSI protection.
