1SDA074025R1 ABB 4000 A HR/VR Kit for Withdrawable ACB

Why Choose the ABB 1SDA074025R1 Emax 2 HR/VR Terminal Kit?

The ABB 1SDA074025R1 is a genuine 4000 A horizontal rear / vertical rear terminal kit designed for compatible withdrawable ABB SACE Emax 2 air circuit breakers. Supplied as a loose connection accessory, the kit enables the rear terminal arrangement of the breaker system to be configured for integration with suitable switchboard busbars and conductors.

As part of the ABB SACE Emax 2 air circuit breaker accessory range, this kit supports HR and VR rear connection arrangements. Horizontal rear and vertical rear terminal configurations give switchboard designers greater flexibility when planning high-current busbar layouts, helping accommodate different electrical distribution assembly designs without changing the fundamental withdrawable breaker architecture.

With a rated current configuration of 4000 A, the 1SDA074025R1 is intended for demanding high-current low-voltage distribution applications. Its loose-kit format allows the appropriate rear connection orientation to be configured during assembly, making it suitable for compatible withdrawable Emax 2 ACB installations in industrial, commercial and infrastructure switchgear.

Flexible High-Current Rear Connections for Withdrawable ACBs

Rear terminal kits provide the electrical interface between an air circuit breaker system and the high-current busbars or conductors within a low-voltage switchboard. Horizontal rear and vertical rear arrangements allow the connection direction to be adapted to the physical design of the assembly, providing greater flexibility when planning busbar routes and switchgear layouts.

The ABB SACE Emax 2 platform is designed around modular breaker and accessory configurations for modern power distribution systems. The 1SDA074025R1 provides an HR/VR connection solution for compatible 4000 A withdrawable ACB installations, allowing the rear terminal orientation to be selected to suit the requirements of the switchboard.

Typical Applications

• ABB SACE Emax 2 withdrawable air circuit breaker installations.
• 4000 A low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process plant switchgear.
• Data centre and critical power distribution systems.
