Why Choose the ABB 1SDA073881R1 Cable Interlock?
The ABB 1SDA073881R1 is a Type A horizontal mechanical interlock cable designed for compatible ABB SACE Emax 2 air circuit breakers. Covering the E1.2 through E6.2 frame range, it forms part of ABB’s mechanical interlocking system for preventing incompatible circuit-breaker operating states in low-voltage power distribution installations.
ABB identifies this accessory as Cable interlock A - HR E1.2...E6.2, where HR denotes the horizontal interlock arrangement. The standard cable is used for a Type A mechanical interlock between two circuit breakers and is ordered for the fixed circuit breaker or the fixed part of a withdrawable circuit breaker.
The 1SDA073881R1 provides the mechanical connection required between compatible breakers and is suitable for E1.2, E2.2, E4.2 and E6.2 Emax 2 frame sizes. A Type A interlocking arrangement is commonly used where two circuit breakers must be mechanically coordinated so that both cannot remain closed simultaneously.

Mechanical Interlocking for Coordinated Power Distribution
Mechanical interlocking is used in switchgear where the operating states of multiple circuit breakers must be physically coordinated. A cable-operated interlock transfers the mechanical state between breakers, providing an independent mechanical constraint that prevents prohibited combinations of closed circuit breakers.
The ABB 1SDA073881R1 is the standard Type A horizontal cable for compatible Emax 2 mechanical interlocking systems. Type A arrangements are designed for two circuit breakers and can be used in applications such as coordination between a main supply and an alternative or emergency supply, with the appropriate ABB interlock supports and operating components selected for the breaker configuration.
Typical Applications
- Mechanical interlocking between two ABB Emax 2 air circuit breakers.
- Main and emergency power supply switching arrangements.
- Low-voltage switchboards and distribution assemblies.
- Fixed Emax 2 circuit-breaker installations.
- Withdrawable Emax 2 circuit-breaker systems using compatible fixed-part accessories.
- Industrial and commercial power distribution systems requiring mechanically coordinated breakers.
