Why Choose the ABB 1SDA055489R1 Terminal Conversion Kit?
The ABB 1SDA055489R1 is a genuine ABB terminal conversion kit for the fixed part of an Emax E4 withdrawable circuit breaker, designed to convert horizontal rear terminals to vertical rear terminals. Configured for a 4-pole E4 installation, the kit comprises four terminal conversion pieces corresponding to the four poles.
Designed specifically for the fixed part (FP) of the withdrawable E4 breaker system, the 1SDA055489R1 allows the rear power connection orientation to be changed from horizontal to vertical. This provides installation flexibility when adapting the circuit breaker to the busbar arrangement and connection geometry of a low-voltage switchboard.
ABB identifies the accessory as KIT W FP 4p HR 4pcs E4 > FP VR, confirming its purpose as a four-piece kit for converting a 4-pole E4 fixed part from horizontal rear (HR) to vertical rear (VR) terminals.
Key Advantages
- Converts horizontal rear terminals to vertical rear terminals.
- Designed for the fixed part of ABB Emax E4 withdrawable circuit breakers.
- Suitable for 4-pole circuit-breaker configurations.
- Includes 4 terminal conversion pieces.
- Allows the rear connection arrangement to be adapted to different busbar layouts.
- Suitable for switchboard construction, modification and refurbishment.
- Genuine ABB accessory designed for the Emax E4 platform.
Key Features
- ABB Emax circuit-breaker accessory.
- Fixed-part terminal conversion kit.
- Horizontal rear (HR) to vertical rear (VR) conversion.
- 4-pole configuration.
- 4-piece terminal set.
- Designed for the E4 breaker frame.
- For the fixed part of a withdrawable circuit breaker.
- IEC accessory configuration.
Horizontal-to-Vertical Fixed-Part Terminal Conversion
In a withdrawable air circuit-breaker installation, the fixed part remains installed within the switchboard and provides the power connection interface for the withdrawable breaker. The orientation of its rear terminals determines how the main switchboard conductors or busbars approach the breaker connection points.
The ABB 1SDA055489R1 provides the four terminal components required to transform a compatible 4-pole E4 fixed part from horizontal rear to vertical rear terminals. This enables the connection geometry to be adapted where a vertical rear arrangement better suits the switchboard design or busbar routing requirements.
Typical Applications
- ABB SACE Emax E4 withdrawable circuit-breaker installations.
- 4-pole E4 fixed parts.
- Horizontal-to-vertical rear terminal conversion.
- Low-voltage power distribution switchboards.
- Busbar connection layout modifications.
- Switchboard refurbishment and retrofit projects.
- Industrial power distribution assemblies.
