1SDA073410R1 ABB E2.2H/MS 1600 3p FHR Switch Disconnector

Why Choose the ABB E2.2H/MS 1600 3p FHR Switch Disconnector?

The ABB E2.2H/MS 1600 3p FHR, order code 1SDA073410R1, is a fixed SACE Emax 2 switch disconnector designed for dependable high-current switching and isolation in demanding low-voltage power-distribution systems. Based on ABB's E2.2 frame, this three-pole unit combines a 1600 A rated uninterrupted current, H performance level and fixed installation with rear horizontal main-circuit terminals.

The E2.2H/MS is a switch-disconnector rather than an Emax 2 circuit breaker equipped with an Ekip electronic protection release. Its primary function is switching and isolation within a suitably protected electrical system, allowing feeders, busbar sections and other distribution circuits to be disconnected while associated protective devices provide the required overcurrent and short-circuit protection.

The H-performance configuration provides a substantial rated short-time withstand current of 85 kA for 1 s and 66 kA for 3 s. Combined with a rated operational voltage of 690 V AC, fixed construction and rear horizontal terminals, the 1SDA073410R1 provides a robust isolation solution for high-current industrial and infrastructure switchboards.

Key Advantages

• High-current 1600 A Emax 2 switch disconnector for demanding low-voltage distribution systems.
• Three-pole configuration for three-phase switching and isolation.
• H performance level provides enhanced short-time current withstand capability.

High-Performance Switching and Isolation for Power Distribution

Switch disconnectors provide a defined means of switching and isolating electrical circuits while operating alongside dedicated protective devices within the distribution system. The ABB E2.2H/MS 1600 combines a substantial 1600 A continuous-current rating with the robust SACE Emax 2 architecture, making it suitable for major switchboard positions where dependable high-current isolation is required without an integral electronic overcurrent trip unit.

Its H performance level provides an 85 kA short-time withstand current for 1 s and 66 kA for 3 s, enabling the switch disconnector to withstand substantial fault currents for the specified duration while the associated protective system clears the fault. Fixed construction and rear horizontal terminals further support integration into industrial and infrastructure switchboards with high-current busbar systems.

Typical Applications

• Main and sectional isolation in high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Transformer secondary distribution assemblies.
• Manufacturing and process-industry switchboards.
• Commercial and infrastructure electrical distribution.
• Utility and critical-power distribution systems.
• Generator and auxiliary power-distribution switchboards.
• Three-phase feeders requiring fixed 1600 A switching and high short-time withstand capability.
