1SDA038335R1 ABB Interlock Cables for 3 Circuit Breakers Vertical Type C

Why Choose the ABB 1SDA038335R1 Interlock Cables?

The ABB 1SDA038335R1 is an interlock cable accessory for three circuit breakers in a vertical arrangement, designed for compatible ABB SACE Emax circuit breakers. Part of the ABB New Emax accessory range, it forms part of a mechanical interlocking system used to coordinate the operating states of multiple circuit breakers.

Mechanical interlocking is used where the operating sequence of several breakers must be physically restricted. By transmitting the breaker mechanism position through dedicated cables, an interlock arrangement can prevent prohibited combinations of circuit breakers from being closed simultaneously, supporting safer and more controlled power distribution schemes.

The 1SDA038335R1 is specified as interlock cables for three circuit breakers arranged vertically and is associated with interlock type C. It is intended for use as part of the appropriate complete ABB mechanical interlocking arrangement rather than as a standalone protection device.

Key Advantages

• Genuine ABB mechanical interlocking accessory for compatible circuit breakers.
• Designed for an installation involving three circuit breakers.
• Suitable for a vertical circuit-breaker arrangement.
• Associated with interlock type C configurations.
• Provides the mechanical connection required to coordinate breaker operating states.

Mechanical Circuit-Breaker Interlocking

Mechanical interlocking provides a physical means of coordinating multiple circuit breakers without depending solely on electrical control logic. The interlock mechanism transfers the operating state of one breaker to the other breakers in the scheme, preventing operating combinations that are prohibited by the selected interlocking arrangement.

The ABB 1SDA038335R1 provides the cable component for a three-breaker vertical type C arrangement. This makes it suitable for installations where three compatible circuit breakers must operate according to a defined mechanical interlocking sequence, such as systems involving multiple power sources, bus sections or controlled supply-transfer arrangements.

Typical Applications

• Mechanical interlocking of three compatible ABB circuit breakers.
• Vertical multi-breaker switchboard arrangements.
• Industrial low-voltage distribution switchboards.
• Commercial power distribution systems.
• Multi-source and supply-transfer arrangements.
• Bus-coupler and sectionalised distribution systems.
