1SDA074102R1 ABB Emax 2 E4.2 Upper Front Fixed-Part Terminal Kit 3 Pieces

Why Choose the ABB 1SDA074102R1 Upper Front Terminal Kit?

The ABB 1SDA074102R1 is a three-piece upper front terminal kit designed for the fixed part of a withdrawable ABB SACE Emax 2 E4.2 air circuit breaker. It provides the upper main-circuit connection components for a 3-pole E4.2 withdrawable installation with an uninterrupted current rating of 4000 A.

ABB identifies the accessory as Kit F Sup E4.2 W FP 3pcs. The Sup/Upper designation identifies the upper terminal position, while W FP indicates that the terminals are intended for the fixed part of a withdrawable circuit-breaker installation. The front-terminal arrangement provides accessible main-circuit connection points for integration with the switchboard power conductors or busbars.

Supplied as three terminal components, the 1SDA074102R1 is intended for three-pole installations. It is a genuine ABB loose/configurable accessory for compatible E4.2 equipment and is also listed for suitable E4.3 applications within the SACE Emax family.

Upper Front Connections for 4000 A Withdrawable Switchgear

A withdrawable air circuit-breaker system uses a permanently installed fixed part to provide the main electrical interface between the removable breaker and the switchboard. The fixed part therefore requires dedicated power terminals to connect the assembly to the incoming and outgoing busbars or conductors.

The ABB 1SDA074102R1 provides the three upper front terminal components required for a compatible 3-pole E4.2 fixed-part arrangement rated at 4000 A. Its loose/configurable format makes it suitable for new switchboard construction, fixed-part configuration, maintenance and refurbishment where the specified ABB upper front connection arrangement is required.

Typical Applications

• ABB SACE Emax 2 E4.2 withdrawable air circuit-breaker installations.
• Compatible E4.3 circuit-breaker applications.
• Three-pole 4000 A low-voltage distribution systems.
• Upper front connections on withdrawable fixed parts.
• Industrial and commercial main distribution switchboards.
• High-current incomer, feeder and bus-coupler installations.
• OEM switchgear construction, maintenance and refurbishment.
