Why Choose the ABB 1SDA058862R1 E1N/MS 1600 Switch-Disconnector?
The ABB 1SDA058862R1 is a robust SACE Emax E1N/MS switch-disconnector designed for high-current switching and isolation in low-voltage power distribution systems. This configuration has a rated current of 1600 A, a 4-pole fixed construction and horizontal rear terminals for integration into industrial switchboards and distribution assemblies.
As part of the ABB SACE Emax range, the E1N/MS is designed for applications requiring dependable switching and isolation rather than an integral overcurrent protection release. Its switch-disconnector architecture provides high current-carrying capability and short-time withstand performance for demanding electrical distribution installations.
The 1SDA058862R1 has a rated operational voltage of up to 690 V AC, a rated insulation voltage of 1000 V and a rated impulse withstand voltage of 12 kV. Its fixed four-pole format with horizontal rear terminals makes it particularly suitable for permanent installation in low-voltage switchboards requiring a 1600 A isolation and switching device.

Reliable Switching and Isolation for Power Distribution
Switch-disconnectors such as the ABB SACE Emax E1N/MS provide switching and isolation of high-current low-voltage circuits. Unlike an air circuit breaker equipped with an electronic protection release, the E1N/MS is intended primarily to provide dependable circuit switching and isolation within a suitably protected electrical distribution system.
The combination of a 1600 A current rating, four-pole construction, fixed mounting and high short-time withstand capability makes the 1SDA058862R1 suitable for demanding industrial switchboards. Its horizontal rear terminals facilitate integration with busbars and other power distribution conductors inside low-voltage assemblies.
Typical Applications
- Industrial low-voltage switchboards.
- Main circuit switching and isolation.
- Four-pole power distribution systems.
- Manufacturing plant electrical distribution.
- Commercial and infrastructure switchgear.
- High-current distribution and isolation assemblies.
