1SDA073896R1 ABB Emax 2 Type A Mechanical Interlock Support

Why Choose the ABB 1SDA073896R1 Type A Mechanical Interlock Support?

The ABB 1SDA073896R1 is a dedicated Type A mechanical interlock support designed for the fixed part of withdrawable ABB SACE Emax 2 E1.2 air circuit breakers. It forms part of ABB's Emax 2 mechanical interlocking system, providing the mounting interface required to integrate an E1.2 withdrawable breaker into a compatible Type A cable interlock arrangement.

Mechanical interlocking provides a physical method of coordinating the operating states of circuit breakers, helping prevent switching combinations that are not permitted by the electrical system design. The 1SDA073896R1 is specifically intended for the fixed part of an E1.2 withdrawable circuit breaker, making it suitable for switchgear installations where dependable mechanical coordination between breakers is required.

ABB identifies this accessory as Support for fixed part Type A E1.2-XT7/M. Within an Emax 2 installation, it is used with the appropriate Type A cable interlock and associated mechanical interlocking components to create the required breaker interlock arrangement.

Reliable Mechanical Interlocking for Emax 2 Switchgear

Mechanical interlocking is used in switchgear where two or more circuit breakers must operate according to a defined sequence or where particular combinations of closed breakers must be physically prevented. Unlike an electrical control interlock alone, a mechanical interlock acts directly through mechanical components to coordinate breaker operation.

The ABB 1SDA073896R1 provides the dedicated support required on the fixed part of an E1.2 withdrawable breaker for a compatible Type A interlocking arrangement. When combined with the appropriate ABB cable interlock and related components, it enables the breaker to participate in a mechanically coordinated switching system.

Typical Applications

• ABB SACE Emax 2 E1.2 withdrawable circuit-breaker installations.
• Low-voltage main distribution switchboards.
• Type A cable-operated mechanical interlocking systems.
• Normal and standby supply switching arrangements.
• Mains and generator power-distribution systems.
• Incomer and bus-coupler interlocking arrangements.
• Industrial and commercial power distribution panels.
• OEM switchgear and electrical panel building.
