1SDA059670R1 ABB SACE New Emax E4 4-Pole Fixed Part with Rear Horizontal Terminals

Why Choose the ABB 1SDA059670R1 New E4 Fixed-Part Accessory?

The ABB 1SDA059670R1 is a SACE New Emax E4 fixed-part configuration intended for use with compatible withdrawable E4 air circuit breakers. Identified by ABB as NEW E4 FP 4P RHT, this component provides the stationary switchboard-mounted portion required for installation and connection of the corresponding withdrawable circuit breaker.

The fixed part is a fundamental element of a withdrawable SACE Emax installation. It remains permanently installed within the switchboard and provides the mechanical interface and primary electrical connections into which the compatible E4 circuit breaker moving part is inserted, connected, tested and withdrawn.

This version is configured as a four-pole E4 fixed part with rear horizontal terminals. The rear-terminal arrangement is designed for connection to the switchboard busbar and conductor system while maintaining the serviceability advantages associated with ABB's withdrawable Emax architecture.

Key Advantages

• Genuine ABB SACE New Emax E4 fixed part for compatible withdrawable circuit breakers.
• Four-pole configuration for three-phase and neutral distribution systems.
• Rear horizontal terminals for switchboard busbar integration.
• Provides the stationary interface for a compatible E4 withdrawable circuit breaker moving part.
• Supports the maintenance and servicing advantages of a withdrawable air circuit breaker system.
• Designed as part of the coordinated ABB SACE New Emax switchgear platform.
• Suitable for demanding industrial, commercial and infrastructure distribution assemblies.

Key Features

• ABB SACE New Emax E4 fixed part.
• Four-pole configuration.
• Designed for compatible withdrawable E4 air circuit breakers.
• Rear horizontal terminal arrangement.
• Stationary switchboard-mounted component.
• Provides the mechanical interface for insertion and withdrawal of the compatible breaker moving part.
• Provides primary electrical connection between the withdrawable breaker and switchboard conductors.
• Designed for coordinated use within ABB SACE New Emax assemblies.

Fixed Parts for Withdrawable Power Distribution Systems

A fixed part is the permanently installed section of a withdrawable air circuit breaker system. While the circuit breaker moving part can be withdrawn for inspection, servicing or replacement, the fixed part remains secured within the switchboard and maintains the interface with the installation's primary conductors and associated switchgear structure.

The ABB SACE New Emax withdrawable architecture is particularly useful in critical distribution systems where maintainability and reduced service interruption are important. The four-pole rear-horizontal-terminal configuration of 1SDA059670R1 makes it suitable for compatible E4 installations requiring connections for all three phases and the neutral conductor.

Typical Applications

• ABB SACE New Emax E4 withdrawable air circuit breaker installations.
• Main low-voltage switchboards and power distribution boards.
• Industrial switchgear assemblies.
• Transformer and generator distribution systems.
• Commercial building electrical infrastructure.
• Critical-power installations requiring maintainable withdrawable switchgear.
• Four-pole distribution systems requiring rear horizontal switchboard connections.
