Why Choose the ABB 1SDA073895R1 Mechanical Interlock Support?
The ABB 1SDA073895R1 is a dedicated mechanical interlock support for SACE Emax 2 air circuit breakers, designed for Type A, B and D mechanical interlocking arrangements involving E2.2, E4.2 and E6.2 breaker frames. It forms part of ABB's Emax 2 mechanical interlocking accessory system for power distribution and switchgear applications.
Designed for use with both fixed circuit breakers (F) and the fixed part of withdrawable circuit breakers (FP), this support provides the mounting interface required by the mechanical interlock arrangement. Mechanical interlocking is used where the operating state of interconnected circuit breakers must be physically coordinated to prevent prohibited switching combinations.
The 1SDA073895R1 supports Type A, Type B and Type D interlock configurations across the Emax 2 E2.2–E6.2 frame range. As an ABB purpose-designed accessory, it provides the correct mechanical interface for integration with compatible Emax 2 interlock levers and cable assemblies.

Reliable Mechanical Interlocking for Emax 2 Switchgear
Mechanical interlocking provides a physical means of coordinating multiple circuit breakers so that switching combinations prohibited by the electrical system design cannot be selected. This is particularly valuable in power distribution arrangements involving alternative supplies, bus couplers and other installations where the operating sequence of multiple breakers must be controlled.
The ABB 1SDA073895R1 provides the support required for compatible Type A, B and D Emax 2 mechanical interlock arrangements. Installed on the appropriate fixed breaker or fixed part of a withdrawable breaker, it works with the corresponding mechanical interlock components to create a robust, purpose-engineered interlocking system.
Typical Applications
- ABB SACE Emax 2 air circuit breaker installations.
- Low-voltage main distribution switchboards.
- Mechanical interlocking between two or three circuit breakers.
- Alternative and standby power supply arrangements.
- Generator and mains switching systems.
- Bus-coupler and multi-incomer switchgear arrangements.
- Industrial and commercial power distribution panels.
- OEM switchgear and electrical panel building.
