1SDA038334R1 ABB Type B Vertical Mechanical Interlock Cables for 3 Circuit Breakers

Why Choose the ABB 1SDA038334R1 Type B Vertical Interlock Cables?

The ABB 1SDA038334R1 is a Type B mechanical interlock cable set designed for three vertically arranged ABB SACE Emax circuit breakers. Part of the ABB New Emax accessories range, it provides the cable components required to establish a mechanically enforced operating relationship between three compatible breakers.

The Type B interlocking arrangement is intended for a three-breaker system comprising two supply circuit breakers and one emergency circuit breaker. Mechanical interlocking physically coordinates the permitted breaker operating states, providing an additional level of switching control that does not depend solely on electrical interlocks, control wiring or automation logic.

The 1SDA038334R1 is specifically configured for a vertical breaker arrangement and uses standard interlocking cables of 2150 mm and 2700 mm. It is suitable for ABB E1, E2, E3, E4 and E6 SACE Emax circuit breakers and is used with the appropriate breaker-specific mechanical interlocking accessories to form the complete interlock system.

Reliable Type B Interlocking for Three Circuit Breakers

Mechanical interlocking provides a physical means of coordinating circuit-breaker operation so that prohibited switching combinations cannot be selected simply through normal breaker operation. In the ABB Type B configuration, three circuit breakers are mechanically coordinated for an arrangement involving two supply sources and one emergency source, making the system suitable for power-distribution schemes requiring controlled source selection.

The ABB 1SDA038334R1 provides the dedicated vertical interlocking cables for this three-breaker arrangement. The cable set is ordered once for each applicable combination of interlocked circuit breakers and is combined with the appropriate breaker-specific interlocking accessories required for the selected E1–E6 installation.

Typical Applications

• ABB SACE Emax E1–E6 circuit-breaker installations.
• Mechanical interlocking of three vertically arranged circuit breakers.
• Two normal supply plus one emergency supply configurations.
• Industrial low-voltage switchboards.
• Emergency and standby power-distribution systems.
• Generator and alternative-source switching arrangements.
• Industrial power systems requiring mechanically enforced breaker operating sequences.
