1SDA038332R1 ABB Type D Horizontal Interlock Cable Set for 3 Emax Circuit Breakers

Why Choose the ABB 1SDA038332R1 Type D Interlock Cable Set?

The ABB 1SDA038332R1 is a genuine Type D horizontal mechanical interlock cable set designed for three compatible ABB SACE Emax air circuit breakers. Part of the ABB Accessories for Emax range, it provides the mechanical cable linkage required for interlocking three breakers in a three-supply arrangement where only one circuit breaker is permitted to remain closed.

The Type D mechanical interlock configuration is intended for three horizontally arranged circuit breakers and three power supplies. Its mechanical operating principle restricts the breaker combination so that only one of the three interconnected circuit breakers can be closed at a time, helping prevent unintended paralleling of independent power supplies.

Designed for ABB SACE Emax E1, E2, E3, E4 and E6 circuit breakers, the 1SDA038332R1 uses standard interlock cables with lengths of 2700 mm and 3550 mm. It is intended to form part of a complete mechanical interlocking installation together with the appropriate breaker-specific interlock mechanisms.

Key Advantages

• Genuine ABB SACE Emax mechanical interlock cable set.
• Designed for three horizontally arranged circuit breakers.
• Type D configuration for three power supplies.
• Mechanically restricts the system so that only one breaker can be closed.
• Suitable for ABB E1, E2, E3, E4 and E6 SACE Emax circuit breakers.
• Supports reliable source selection and mechanical interlocking in industrial switchboards.

Key Features

• ABB Accessories for Emax range.
• Horizontal Type D mechanical interlock cable set.
• Designed to interlock three circuit breakers.
• Configuration for three power supplies with only one breaker closed.
• Standard cable lengths of 2700 mm and 3550 mm.

• Designed for ABB SACE Emax air circuit breakers.
• Mechanical interlocking operates independently of electrical control logic.

Reliable Mechanical Interlocking for Multiple Power Supplies

Mechanical interlocking provides a direct physical relationship between multiple circuit breakers, preventing prohibited switching combinations independently of electrical control software or interlocking logic. This makes it particularly useful in distribution systems where inadvertent paralleling of independent power sources must be prevented.

The ABB 1SDA038332R1 Type D arrangement is specifically designed for three power supplies and three circuit breakers. By mechanically permitting only one interconnected breaker to be closed at a time, the system supports controlled source selection in industrial and critical power-distribution switchboards.

Typical Applications

• Three-breaker mechanical interlocking systems.
• Three-source power-distribution arrangements.
• Industrial low-voltage distribution switchboards.
• Multiple-source changeover systems.
• Generator and mains source-selection systems.
• Critical power and standby supply installations.
• ABB SACE Emax E1–E6 air circuit-breaker systems.
