1SDA059819R1 ABB E2 W FP 4P VR-HR SACE Emax Fixed Part

Why Choose the ABB 1SDA059819R1 E2 W Fixed Part?

The ABB 1SDA059819R1 is a SACE Emax E2 fixed part designed for use with compatible withdrawable ABB E2 air circuit breakers. Identified by ABB as E2 W FP 4P VR-HR New, this four-pole fixed section forms the stationary component of a withdrawable circuit-breaker installation, providing the mechanical interface and main power connections required within low-voltage electrical switchgear.

Designed for the ABB SACE Emax E2 frame, the 1SDA059819R1 is rated for 690 V AC and features a four-pole configuration suitable for three-phase four-wire distribution systems. Its VR-HR arrangement provides vertical rear upper terminals and horizontal rear lower terminals, supporting switchboard designs where the incoming and outgoing busbar connections require different orientations.

The fixed part remains installed within the switchboard while a compatible withdrawable E2 circuit-breaker moving part can be inserted, isolated and removed as required. This modular architecture supports efficient inspection, maintenance and breaker replacement while allowing the principal switchboard power connections to remain installed.

Key Advantages

• Genuine ABB SACE Emax E2 fixed part for withdrawable air circuit breakers.
• Four-pole configuration suitable for three-phase four-wire electrical distribution.

VR-HR Fixed Part for Withdrawable Emax Installations

Withdrawable air circuit-breaker systems separate the assembly into a removable circuit-breaker moving part and a permanently installed fixed part. The ABB 1SDA059819R1 provides the stationary interface for compatible E2 equipment, allowing the circuit breaker to be connected to, isolated from and removed from the electrical system while the principal switchboard connections remain in position.

The VR-HR terminal configuration combines vertical rear upper terminals with horizontal rear lower terminals. This mixed connection arrangement is particularly useful where the incoming and outgoing switchboard busbars require different orientations, providing a purpose-designed connection interface while retaining the maintenance advantages of the ABB Emax withdrawable circuit-breaker architecture.

Typical Applications

• ABB SACE Emax E2 withdrawable circuit-breaker installations.
• Main low-voltage electrical distribution boards.
• Industrial switchboards and switchgear assemblies.
• Three-phase four-wire power distribution systems.
• Manufacturing and process plant electrical distribution.
• Commercial and infrastructure power distribution systems.
• Transformer and generator distribution switchboards.
• Switchgear requiring mixed vertical and horizontal rear busbar connections.
