1SDA059904R1 ABB E3/E W FP 4p 1000V DC HR-HR New Fixed Part 3200 A

Why Choose the ABB E3/E W FP 4p 1000V DC HR-HR New Fixed Part?

The ABB E3/E W FP 4p 1000V DC HR-HR new, order code 1SDA059904R1, is a specialised SACE Emax E3/E fixed part for withdrawable circuit breakers designed for high-capacity direct-current power distribution. As part of the ABB New Emax family, it provides the permanently installed mechanical and electrical interface required for a compatible E3/E withdrawable circuit breaker in 1000 V DC systems.

This version features a four-pole configuration with horizontal rear terminals at both the upper and lower connections. The HR-HR arrangement provides rear flat horizontal power connections for integration with suitably engineered DC busbar systems, while the withdrawable architecture allows the compatible circuit breaker to be removed for inspection, servicing or replacement while the fixed part remains installed.

With a rated uninterrupted current of 3200 A and a rated voltage of 1000 V DC, the 1SDA059904R1 is engineered for demanding high-power DC distribution duties. Its combination of four-pole construction, high DC voltage capability and SACE Emax withdrawable architecture makes it suitable for industrial DC networks and other high-capacity applications where reliable switching, isolation and maintainability are essential.

Reliable High-Voltage DC Circuit Breaker Integration

A fixed part forms the permanently installed section of a withdrawable circuit breaker assembly, providing the mechanical mounting and main electrical connection interface between the removable breaker and the switchboard. The ABB 1SDA059904R1 is specifically configured for the E3/E 1000 V DC system, enabling the compatible breaker to be withdrawn for inspection or maintenance while the fixed assembly remains installed.

The combination of a 3200 A uninterrupted current rating, 1000 V DC voltage rating and horizontal rear upper and lower terminals makes this fixed part particularly suitable for engineered high-power DC switchgear. Its four-pole configuration and rear horizontal connection arrangement support purpose-designed DC distribution assemblies where electrical capacity, connection geometry and maintainability are key requirements.

Typical Applications

• High-capacity industrial DC distribution systems.
• 1000 V DC switchgear assemblies.
• Withdrawable SACE Emax E3/E circuit breaker installations.
• Industrial DC main distribution boards.
• Power conversion and energy infrastructure systems.
• Engineered high-current DC busbar and distribution assemblies.
• OEM switchgear and specialised panel-building applications.
