1SDA072648R1 ABB E6.2H 6300 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E6.2H 6300 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker?

The ABB 1SDA072648R1 is a high-performance SACE Emax 2 E6.2H air circuit breaker (ACB) designed for advanced protection, monitoring and control of demanding low-voltage electrical distribution systems. Rated at 6300 A, this three-pole breaker combines ABB’s high-current E6.2H frame with an advanced Ekip Hi-Touch LSI electronic trip unit.

As part of the ABB SACE Emax 2 air circuit breaker series, the E6.2H is engineered for high-current industrial switchboards, data centres, infrastructure, manufacturing facilities and critical power distribution. The Ekip Hi-Touch electronic release provides sophisticated protection, measurement and monitoring capabilities, while its LSI configuration provides long-time overload, short-time delayed and instantaneous short-circuit protection.

The 1SDA072648R1 is a three-pole withdrawable mobile part (WMP) with a rated uninterrupted current of 6300 A and rated voltage of 690 V. The E6.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400 V AC, making it suitable for large electrical networks where high continuous currents, substantial fault levels and dependable protection coordination are essential.

Advanced High-Current Circuit Protection

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage electrical systems against damaging overload and short-circuit conditions. The E6.2H frame combines a substantial 6300 A continuous current rating with 100 kA short-circuit interruption capability, making this configuration suitable for large electrical networks where fault levels, selectivity and continuity of supply are critical considerations.

The Ekip Hi-Touch LSI electronic trip unit provides advanced long-time overload, short-time delayed and instantaneous short-circuit protection together with sophisticated measurement and monitoring capabilities. The LSI configuration does not include integrated earth-fault protection, making it particularly appropriate where earth-fault protection is provided separately or is not required within the breaker trip unit.

Typical Applications

• Main incoming protection for very high-current low-voltage switchboards.
• Large industrial power distribution systems.
• Transformer secondary and main distribution protection.
• Data centres and high-availability electrical infrastructure.
• Critical power distribution installations.
• Manufacturing plants and process facilities.
• Large commercial and infrastructure projects.
• Electrical systems with high prospective short-circuit currents.
