1SDA073897R1 ABB Emax 2 Type C Mechanical Interlock Support

Why Choose the ABB 1SDA073897R1 Type C Mechanical Interlock Support?

The ABB 1SDA073897R1 is a dedicated Type C mechanical interlock support for ABB SACE Emax 2 air circuit breakers. Identified by ABB as Support F/FP Type C E2.2...E6.2, it is designed for mechanical interlocking between two or three compatible circuit breakers in low-voltage power distribution systems.

The support is suitable for fixed circuit breakers and the fixed parts of withdrawable circuit breakers, providing the mounting interface required for a Type C mechanical interlocking arrangement. It is compatible with the ABB Emax 2 E2.2, E4.2 and E6.2 frame sizes and forms part of the wider Emax 2 mechanical interlock accessory system.

Mechanical interlocking provides a physical means of coordinating circuit-breaker operating states independently of electrical control logic. The 1SDA073897R1 enables the appropriate mechanical interlock components to be installed on compatible Emax 2 breakers or fixed parts, supporting controlled switching arrangements involving two or three circuit breakers.

Mechanical Support for Type C Circuit-Breaker Interlocking

Mechanical interlocking is used in switchgear to physically restrict circuit breakers from entering prohibited combinations of operating states. This is particularly important in installations containing multiple incoming supplies, bus sections or alternative sources where the switching sequence must remain mechanically coordinated.

The ABB 1SDA073897R1 provides the support required for a Type C mechanical interlocking arrangement between two or three circuit breakers. Installed on a fixed circuit breaker or the fixed part of a withdrawable breaker, it works with the appropriate ABB interlock cables, levers and associated components to form the required Emax 2 mechanical interlocking system.

Typical Applications

• Type C mechanical interlocking of ABB Emax 2 circuit breakers.
• Two- and three-circuit-breaker interlocking arrangements.
• Main, bus-tie and alternative supply switchgear configurations.
• Fixed Emax 2 E2.2, E4.2 and E6.2 installations.
• Withdrawable Emax 2 installations using compatible fixed parts.
• Industrial and commercial low-voltage power distribution switchboards.
