Why Choose the ABB 1SDA073893R1 Emax 2 Type A Mechanical Interlock Support?
The ABB 1SDA073893R1 is a Type A mechanical interlock support designed for fixed ABB SACE Emax 2 E1.2 air circuit breakers. Identified as Support fixed circuit breaker Type A E1.2, it forms part of ABB's mechanical interlocking system used to coordinate the operation of two circuit breakers.
This support is the floor-mounted Type A version for a fixed E1.2 circuit breaker. It provides the mechanical mounting interface required for the associated interlocking components, allowing a correctly configured mechanical interlock to prevent incompatible operating states between interconnected breakers without relying on electrical control logic.
The ABB 1SDA073893R1 is intended for SACE Emax 2 E1.2 applications and is also specified for compatible XT7 and XT7M circuit breakers. For an interlocking arrangement involving two fixed E1.2 circuit breakers, the appropriate support is required for each breaker together with the other components specified for the complete ABB Type A mechanical interlock system.

Type A Mechanical Interlocking for Fixed Emax 2 Circuit Breakers
Mechanical interlocking is used where the operating states of two circuit breakers must be physically coordinated. Rather than depending solely on electrical signalling or control logic, the ABB interlocking system uses mechanical components to restrict breaker operation according to the selected interlock arrangement. This is particularly useful in applications involving alternative supplies, transformers, generators, bus couplers and other distribution configurations where simultaneous breaker states need to be controlled.
The ABB 1SDA073893R1 provides the floor-mounted Type A support for a fixed Emax 2 E1.2 circuit breaker. It forms one component of the complete mechanical interlocking arrangement and must be combined with the appropriate ABB interlock cables and other required components for the intended installation.
Typical Applications
- ABB SACE Emax 2 E1.2 fixed air circuit breakers.
- Type A mechanical interlocking between two circuit breakers.
- Alternative mains and standby supply arrangements.
- Generator and utility incomer interlocking.
- Transformer incomer and bus-coupler schemes.
- Industrial and commercial low-voltage switchboards.
- Critical-power and infrastructure distribution systems.
