1SDA054743R1 ABB T4 W FP 3p EF 3-Pole Withdrawable Circuit Breaker Fixed Part

Why Choose the ABB 1SDA054743R1 T4 W FP 3p EF Fixed Part?

The ABB 1SDA054743R1 is a three-pole fixed part for a withdrawable Tmax T4 circuit breaker, designed as part of the ABB Tmax low-voltage moulded-case circuit-breaker system. Identified by ABB as T4 W FP 3p EF, this fixed-part assembly provides the stationary interface required for installation of a compatible withdrawable T4 breaker.

The fixed part remains installed within the switchboard while the compatible withdrawable circuit breaker can be removed for inspection, servicing or replacement. This arrangement helps simplify maintenance procedures and can reduce the amount of disturbance required to the permanent electrical connections when working on the breaker.

Featuring a three-pole configuration and extended front terminals, the 1SDA054743R1 is intended for compatible ABB Tmax T4 withdrawable circuit-breaker installations. Its purpose-built construction supports secure integration into industrial switchboards, distribution panels and low-voltage power distribution assemblies.

Key Advantages

• Purpose-designed fixed part for withdrawable ABB Tmax T4 circuit breakers.
• Three-pole configuration for compatible three-phase installations.
• Extended front terminal arrangement for electrical connection.
• Allows the compatible withdrawable breaker to be removed while the fixed part remains installed.
• Supports easier circuit-breaker inspection, servicing and replacement in suitable switchboard designs.
• Designed as part of the established ABB Tmax T4–T8 system.

Flexible Withdrawable Circuit-Breaker Installation

Withdrawable circuit-breaker systems separate the removable breaker from a permanently installed fixed part. The fixed assembly provides the interface with the switchboard installation, while the compatible circuit breaker can be withdrawn when maintenance, testing or replacement is required.

The ABB 1SDA054743R1 provides this fixed interface for compatible three-pole Tmax T4 withdrawable circuit breakers. Its extended front terminal arrangement supports connection within suitable low-voltage distribution assemblies, making it a practical component for switchboards where maintainability and breaker accessibility are important.

Typical Applications

• ABB Tmax T4 withdrawable circuit-breaker installations.
• Industrial low-voltage switchboards.
• Electrical distribution panels.
• Manufacturing and process installations.
• Commercial and industrial power distribution systems.
• Installations requiring removable circuit breakers for maintenance or replacement.
