Why Choose the ABB 1SDA052311R1 Terminal Conversion Kit?
The ABB 1SDA052311R1 is a genuine ABB terminal conversion kit for New Emax E1-A fixed circuit breakers, designed to convert horizontal rear terminals to a vertical rear terminal arrangement. Supplied as a half kit for a 4-pole breaker, it provides the components required for either the upper or lower terminal set.
As part of the ABB New Emax accessory range, the kit provides a manufacturer-engineered method of changing the rear connection orientation of an E1-A fixed circuit breaker. This enables the breaker connection arrangement to be adapted to the busbar layout and space requirements of compatible low-voltage switchboards.
The 1SDA052311R1 is specified as a 1/2 kit, 4-pole, fixed, horizontal rear to vertical rear (HR>VR). One kit is prepared for either the top or bottom terminals; conversion of the complete circuit breaker requires two kits.
Key Advantages
- Converts horizontal rear terminals to vertical rear terminals.
- Designed specifically for ABB New Emax E1-A fixed circuit breakers.
- Suitable for 4-pole breaker configurations.
- Supplied as a half conversion kit for top or bottom application.
- Allows the terminal orientation to be adapted to switchboard busbar arrangements.
- Genuine ABB accessory designed for correct mechanical and electrical integration.
Key Features
- ABB New Emax accessory range.
- Rear terminal conversion kit.
- Horizontal rear (HR) to vertical rear (VR) conversion.
- 4-pole configuration.
- For fixed circuit breakers.
- Designed for the E1-A frame.
- Each kit covers one half of the breaker terminals — top or bottom.
- Two kits are required to convert all terminals on a complete circuit breaker.
Flexible Rear Terminal Configuration
Rear terminal orientation can be important when integrating an air circuit breaker into a switchboard because the available cabinet space and busbar routing determine how the breaker connections can be arranged. Converting from horizontal rear to vertical rear terminals allows compatible E1-A fixed breakers to accommodate a different busbar approach without replacing the complete circuit breaker.
The ABB 1SDA052311R1 provides the conversion components for one terminal side of a 4-pole E1-A breaker. Because the kit is prepared for either top or bottom application, two 1SDA052311R1 kits are required when converting both sets of terminals on the complete breaker.
Typical Applications
- ABB New Emax E1-A fixed circuit-breaker installations.
- 4-pole low-voltage air circuit breakers.
- Horizontal-to-vertical rear terminal conversion.
- Low-voltage distribution switchboards.
- Busbar connection layout modifications.
- Switchboard refurbishment and breaker retrofitting.
- Industrial power distribution systems.
