1SDA073409R1 ABB E2.2N/MS 1600 3p FHR Switch Disconnector

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

The ABB E2.2N/MS 1600 3p FHR, order code 1SDA073409R1, is a fixed SACE Emax 2 switch disconnector designed for dependable 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, N performance level and fixed installation for industrial, infrastructure and commercial switchboards.

The E2.2N/MS is a switch-disconnector rather than an Emax 2 circuit breaker equipped with an Ekip electronic protection release. It is therefore intended primarily to provide switching and isolation within a suitably protected electrical system, allowing circuits or sections of a switchboard to be positively disconnected while associated protective devices provide the required overcurrent and short-circuit protection.

A key characteristic of this N-performance configuration is its 66 kA rated short-time withstand current for 1 s. The 1SDA073409R1 is a fixed three-pole version with adjustable rear horizontal terminals (FHR), providing a practical connection arrangement for integration into high-current low-voltage switchboards.

Key Advantages

• High-current 1600 A Emax 2 switch disconnector for major low-voltage distribution systems.
• Three-pole configuration for three-phase switching and isolation.
• 66 kA short-time withstand current for 1 s supports demanding high-fault-level installations.
• Fixed installation provides a robust permanent switchboard arrangement.
• Adjustable rear horizontal terminals provide flexible rear busbar and conductor connection.
• Suitable for applications at up to 690 V AC.
• Part of ABB's established SACE Emax 2 low-voltage switching platform.

Reliable High-Current Switching and Isolation

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

Its 66 kA short-time withstand current for 1 s enables the switch disconnector to withstand substantial prospective fault current for the specified duration while the associated protection system clears the fault. Combined with fixed mounting and adjustable rear horizontal terminals, the 1SDA073409R1 provides a practical solution for high-current industrial and infrastructure distribution assemblies.

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 building electrical distribution.
• Infrastructure and utility distribution systems.
• Generator and auxiliary power-distribution switchboards.
• Three-phase feeders requiring fixed 1600 A switching and isolation.
