Why Choose the ABB 1SDA074056R1 SHR Terminal Kit?
The ABB 1SDA074056R1 is a four-piece spread horizontal rear (SHR) terminal kit designed for ABB SACE Emax 2 E2.2 air circuit breakers. Rated for an uninterrupted current of 2500 A, the kit provides the main rear connection components required for a 4-pole fixed E2.2 installation.
The SHR configuration provides spread horizontal rear terminals, positioning the main power connections at the rear of the circuit breaker with a spread arrangement suitable for compatible switchboard busbars. This connection geometry supports high-current installations where rear access, conductor spacing and efficient integration with the switchboard busbar system are important.
Supplied as four loose terminal components, the 1SDA074056R1 is a configurable IEC accessory. ABB specifies it for E2.2 equipment and also lists suitability for E2.3, providing a genuine ABB terminal solution for compatible SACE Emax 2 and SACE Emax 3 applications.

Spread Horizontal Rear Connections for 2500 A Switchgear
The main terminals of an air circuit breaker form the electrical interface between the breaker and the switchboard busbars. The spread horizontal rear arrangement positions the main power connections at the rear while spreading the connection points to provide suitable geometry for compatible high-current busbar systems.
The ABB 1SDA074056R1 provides four SHR terminal components for a four-pole fixed E2.2 installation with an uninterrupted current rating of 2500 A. Its loose and configurable format makes it suitable for new switchboard construction, circuit-breaker configuration, maintenance and refurbishment where ABB's specified spread horizontal rear connection arrangement is required.
Typical Applications
- ABB SACE Emax 2 E2.2 fixed air circuit-breaker installations.
- Compatible E2.3 circuit-breaker applications.
- Four-pole 2500 A low-voltage distribution systems.
- Spread horizontal rear busbar connections.
- Industrial and commercial main distribution switchboards.
- Main incomer, feeder and bus-coupler installations.
