1SDA038333R1 ABB Type A Vertical Mechanical Interlock Cables for 2 Circuit Breakers

Why Choose the ABB 1SDA038333R1 Vertical Interlock Cables?

The ABB 1SDA038333R1 is a Type A mechanical interlock cable set designed for two vertically arranged ABB SACE Emax circuit breakers. Part of the ABB New Emax accessories range, it provides the cable component required to create a mechanical interlocking arrangement between two compatible breakers.

Mechanical interlocking is used where the operating state of one circuit breaker must mechanically restrict the operation of another. The Type A arrangement is intended for two circuit breakers, helping prevent incompatible simultaneous breaker states without relying solely on electrical control logic.

The 1SDA038333R1 is specified for vertical breaker arrangements and uses standard cables with a length of 2150 mm. It is suitable for ABB E1, E2, E3, E4 and E6 SACE Emax circuit breakers and forms part of a complete mechanical interlocking system using the appropriate breaker-specific interlocking accessories.

Reliable Mechanical Interlocking Between Two Circuit Breakers

Mechanical interlocking provides a physical means of coordinating the operating states of circuit breakers. In a Type A two-breaker arrangement, the mechanical interlock prevents operating combinations that are prohibited by the interlocking scheme, providing an additional layer of control that does not depend solely on electrical signals or software logic.

The ABB 1SDA038333R1 provides the vertical 2150 mm cable set for this interlocking arrangement. It is ordered once for each applicable combination of interlocked breakers and is used together with the appropriate mechanical interlocking components for the particular E1–E6 breaker installation.

Typical Applications

• ABB SACE Emax E1–E6 circuit-breaker installations.
• Mechanical interlocking of two vertically arranged circuit breakers.
• Main and alternative supply switching arrangements.
• Industrial low-voltage switchboards.
• Power-distribution and switchgear assemblies.
• Electrical systems requiring mechanically enforced breaker operating sequences.
• Fixed or withdrawable Emax breaker installations using the appropriate complementary interlock accessories.
