Why Choose the ABB 1SDA073885R1 Cable Interlock A - VR?
The ABB 1SDA073885R1 is a genuine cable interlock accessory designed for ABB SACE Emax 2 E1.2 through E6.2 air circuit breakers. Identified as Cable interlock A - VR E1.2...E6.2, it forms part of the Emax 2 mechanical interlocking system used to coordinate the operation of multiple circuit breakers in low-voltage power distribution installations.
Mechanical cable interlocks are used where the operating state of one circuit breaker must be dependent on the state of another. This provides a mechanical means of preventing prohibited breaker combinations, supporting transfer, source-selection and distribution arrangements without relying solely on electrical control logic.
The 1SDA073885R1 is the A - VR cable interlock version and is designed for the broad Emax 2 E1.2, E2.2, E4.2 and E6.2 frame range. Its manufacturer-engineered design provides compatibility with the intended ABB breaker mechanisms and supports dependable mechanical interlocking within correctly configured switchgear systems.

Reliable Mechanical Circuit Breaker Interlocking
Mechanical interlocking is commonly used in switchgear where defined circuit breakers must not be closed simultaneously. A cable-operated system transfers the mechanical state between compatible breakers, helping enforce the permitted operating sequence independently of normal electrical control commands.
ABB Emax 2 cable interlock accessories are designed to work with the breaker operating mechanisms as part of a complete interlocking arrangement. The 1SDA073885R1 A - VR version supports correctly engineered installations using E1.2 through E6.2 circuit breaker frames.
Typical Applications
- ABB SACE Emax 2 E1.2 through E6.2 air circuit breakers.
- Main and standby power source arrangements.
- Transformer and generator source-selection systems.
- Bus-tie and bus-coupler switchgear configurations.
- Industrial low-voltage distribution switchboards.
- Installations requiring mechanically enforced breaker operating sequences.
