Why Choose the ABB 1SDA050049R1 Emax E4-A Rear Vertical Terminal Conversion Kit?
The ABB 1SDA050049R1 is a dedicated three-pole terminal conversion kit designed for fixed ABB SACE Emax E4-A air circuit breakers. Identified by ABB as KIT 1/2 3p F HR > F VR E4-A, it converts the breaker connection arrangement from horizontal rear terminals to rear vertical terminals.
As part of the ABB SACE Emax / New Emax accessory range, the 1SDA050049R1 provides a manufacturer-designed solution for adapting E4-A power connections to suit alternative switchboard busbar layouts. Rear vertical terminals allow the main power connections to approach the breaker vertically from the rear, providing additional flexibility when arranging low-voltage distribution equipment.
The kit is specifically intended for three-pole fixed Emax E4-A circuit breakers. ABB documentation identifies terminal conversion accessories of this type as half-kits used on the upper or lower breaker terminals, with two matching kits required when both sides of a three-pole breaker are to be converted.

Flexible Rear Connections for Emax E4-A Switchgear
Terminal orientation is an important consideration when integrating an air circuit breaker into a low-voltage switchboard. Rear vertical terminals allow the main power conductors or busbars to be routed vertically behind the breaker, providing an alternative to horizontal rear connections where the switchboard architecture requires a different connection direction.
The ABB 1SDA050049R1 is engineered specifically for three-pole fixed Emax E4-A applications. Its dedicated terminal components allow compatible E4-A breakers to be configured with rear vertical connections while retaining a manufacturer-designed interface with the ABB SACE Emax platform.
Typical Applications
- ABB SACE Emax E4-A air circuit breaker installations.
- Three-pole fixed low-voltage circuit breakers.
- Industrial power distribution switchboards.
- Low-voltage switchgear and distribution assemblies.
- Horizontal rear to rear vertical terminal conversions.
- Switchboard upgrades, modifications and refurbishment projects.
