1SDA074043R1 ABB Emax 2 E6.2 6300 A VR/HR Terminal Kit 4-Pole

Why Choose the ABB 1SDA074043R1 Emax 2 VR/HR Terminal Kit?

The ABB 1SDA074043R1 is a genuine four-pole vertical rear/horizontal rear terminal kit for ABB SACE Emax 2 E6.2 air circuit breakers with a rated uninterrupted current of 6300 A. Identified by ABB as KIT VR/HR E6.2 IU=6300 4PCS, it provides four main-circuit terminal assemblies for high-current switchgear connections.

The VR/HR terminal arrangement supports rear connection geometry for integrating the breaker with the switchboard busbar system. Vertical rear and horizontal rear arrangements give panel designers flexibility when matching the circuit breaker to the physical routing and orientation of high-current busbars within a low-voltage assembly.

Supplied as a four-piece kit, the 1SDA074043R1 is intended for a four-pole E6.2 installation rated at 6300 A. Its ABB-engineered construction provides a purpose-designed main-circuit interface for demanding industrial, infrastructure and critical-power distribution applications.

Flexible High-Current Rear Connections

Large-frame air circuit breakers require robust main-circuit connections capable of integrating with substantial switchboard busbar systems. Rear terminal arrangements keep these high-current connections behind the breaker and allow the busbar architecture to be designed around the available switchgear space and required conductor routing.

The ABB 1SDA074043R1 provides four VR/HR terminal assemblies for a four-pole E6.2 application with an uninterrupted current rating of 6300 A. This makes the kit suitable for high-capacity distribution assemblies where the breaker must interface with vertically or horizontally arranged rear busbars.

Typical Applications

• ABB SACE Emax 2 E6.2 air circuit-breaker installations.
• Four-pole 6300 A low-voltage distribution systems.
• Switchgear with vertical or horizontal rear busbar connections.
