1SDA061373R1 ABB E1N-A/MS 1200 1200 A 3-Pole Withdrawable Switch Disconnector

Why Choose the ABB E1N-A/MS 1200 3-Pole Switch Disconnector?

The ABB 1SDA061373R1 is a high-performance SACE Emax E1N-A/MS switch disconnector moving part designed for reliable isolation and switching in demanding low-voltage power distribution systems. Rated at 1200 A, this three-pole device forms part of ABB's established SACE Emax range and is intended for industrial and commercial switchgear applications requiring dependable high-current disconnection.

As an E1N-A/MS configuration, the 1SDA061373R1 is a switch disconnector rather than an overcurrent-protection circuit breaker. It provides a robust means of switching and isolating electrical circuits and can be incorporated into coordinated installations where separate protective devices provide the required overload and short-circuit protection.

The 1SDA061373R1 is supplied as a withdrawable moving part (W MP) with a three-pole configuration and 1200 A frame rating. ABB specifies the E1N-A/MS 1200 configuration with a rated short-time current of 50 kA at 480 V, making it suitable for high-capacity switchboards and power distribution assemblies.

Reliable Switching and Isolation for Power Distribution

Switch disconnectors such as the ABB E1N-A/MS provide a reliable means of disconnecting and isolating sections of a low-voltage electrical installation. This is particularly important during planned maintenance and servicing, where circuits must be separated from the electrical supply as part of an appropriately designed isolation procedure.

The withdrawable construction allows the moving part to be disconnected and withdrawn from its corresponding fixed part, supporting maintainability within switchboard installations. With its 1200 A current rating and 50 kA short-time current capability at 480 V, the E1N-A/MS is well suited to demanding industrial and commercial distribution systems.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• High-current feeder isolation.
• Power distribution switchgear assemblies.
• Electrical systems requiring withdrawable switching and isolation.
• ABB SACE Emax switchboard installations.
