1SDA072262R1 ABB E2.2H 800 Ekip Dip LSI 3p WMP Air Circuit Breaker

Why Choose the ABB E2.2H 800 Ekip Dip LSI 3p WMP Air Circuit Breaker?

The ABB E2.2H 800 Ekip Dip LSI 3p WMP, order code 1SDA072262R1, is a high-performance air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for reliable protection and control of demanding low-voltage electrical distribution systems. Combining the high-breaking-capacity E2.2H frame with an 800 A rated uninterrupted current and Ekip Dip LSI electronic trip unit, it provides comprehensive overload and short-circuit protection for industrial, commercial and infrastructure power systems.

The Ekip Dip LSI solid-state trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Its adjustable protection settings enable effective coordination with other protective devices, while the E2.2H performance level provides the interruption capability required for installations with high prospective fault currents.

With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 100 kA at 400–440 V AC and a short-time withstand current of 85 kA for 1 s, the E2.2H 800 is engineered for demanding power-distribution applications. This three-pole WMP version is supplied as the withdrawable moving part and includes four auxiliary changeover contacts together with circuit-breaker open/closed position indication.

Reliable High-Capacity Electrical Protection

ABB SACE Emax 2 air circuit breakers protect low-voltage electrical networks against potentially damaging overloads and short circuits. The E2.2H frame combines high fault-interruption performance with electronic protection, making it suitable for main distribution boards, industrial switchgear and other installations where high prospective short-circuit currents require robust protection.

The Ekip Dip LSI trip unit adds short-time protection to the long-time and instantaneous functions, enabling greater selectivity and coordination within the electrical distribution network. This makes the 1SDA072262R1 particularly suitable for systems where maintaining continuity of supply and isolating faults as close as possible to their source are important design objectives.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Main incoming electrical supplies.
• Manufacturing and process plants.
• Commercial building electrical distribution.
• Infrastructure and utility installations.
• High fault-level low-voltage switchgear assemblies.
