1SDA061479R1 ABB E4S-A/MS 3600 3P F HR Switch-Disconnector

Why Choose the ABB E4S-A/MS 3600 3P F HR Switch-Disconnector?

The ABB E4S-A/MS 3600 3P F HR, order code 1SDA061479R1, is a heavy-duty 3600 A three-pole fixed switch-disconnector from the ABB SACE Emax range. Designed for high-current low-voltage power distribution, it provides dependable switching and isolation for demanding industrial, commercial and infrastructure electrical installations.

The E4S-A/MS designation identifies an E4-frame non-automatic switch with ABB's S performance level. This version uses a fixed (F) installation and horizontal rear (HR) terminals, providing a robust arrangement for permanent switchboard installations with substantial rear-connected busbars and conductors.

With a 3600 A frame size, three-pole construction and a rated voltage of 600 V AC, the E4S-A/MS 3600 is engineered for substantial three-phase distribution duties. The E4S-A/MS platform has a 65 kA rated short-time current, a maximum rated voltage of 635 V AC and a 50–60 Hz operating frequency, making it suitable for demanding low-voltage switchgear assemblies.

Key Advantages

• Genuine ABB SACE Emax non-automatic switch-disconnector.
• 3600 A frame size for demanding high-current power distribution.
• Three-pole configuration for three-phase switching and isolation.

Reliable High-Current Switching and Isolation

Non-automatic switches such as the ABB E4S-A/MS provide controlled switching and electrical isolation within high-current low-voltage distribution systems. Unlike an automatic circuit breaker equipped with an electronic protection trip unit, the /MS configuration is intended primarily for switching and isolation, with the required overcurrent and fault protection coordinated elsewhere in the electrical installation.

The fixed E4 configuration is particularly well suited to permanent switchboard installations. Its horizontal rear terminals provide an effective connection arrangement for high-current busbars, while the 3600 A frame size and S performance level support demanding main distribution, feeder and isolation duties.

Typical Applications

• High-current low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Main incomer and feeder isolation duties.
• Manufacturing and process plant switchgear.
• Commercial and infrastructure electrical distribution.
• Large motor control centres and industrial switchgear assemblies.
• Fixed switchboards requiring high-current three-phase switching and isolation.
