Why Choose the ABB 1SDA054756R1 T5 400 W FP 3P VR Fixed Part?

The ABB 1SDA054756R1 is a three-pole fixed part for a withdrawable ABB Tmax T5 400 moulded-case circuit breaker. Part of the established ABB Tmax T4–T8 circuit-breaker range, this fixed-part assembly provides the stationary mounting and electrical connection interface required for a compatible withdrawable T5 400 circuit breaker.

In a withdrawable installation, the fixed part remains permanently mounted within the switchboard while the compatible circuit breaker can be withdrawn for inspection, testing, servicing or replacement. This arrangement supports maintainable low-voltage distribution systems by allowing access to the breaker without removing the fixed electrical connection assembly.

The 1SDA054756R1 features a three-pole configuration with vertical rear (VR) terminals and a rated uninterrupted current of 400 A. Designed specifically for the ABB Tmax T5 400 platform, it has compact dimensions of 209 × 171 × 50 mm and is suitable for industrial and commercial low-voltage switchboard applications.

Key Advantages

  • Purpose-designed fixed part for withdrawable ABB Tmax T5 400 circuit breakers.
  • 400 A rated uninterrupted current for low-voltage distribution applications.
  • Three-pole configuration suitable for compatible three-phase installations.
  • Vertical rear terminals for the specified switchboard connection arrangement.
  • Allows the compatible circuit breaker to be withdrawn while the fixed part remains installed.
  • Supports maintainable and modular industrial switchboard designs.

Key Features

  • ABB Tmax T5 400 fixed part.
  • Designed for a withdrawable circuit-breaker configuration.
  • 400 A rated uninterrupted current.
  • Three-pole (3P) arrangement.
  • Vertical rear (VR) terminal configuration.
  • Stationary component of the withdrawable circuit-breaker assembly.
  • Designed for compatible ABB Tmax T5 moulded-case circuit breakers.

Flexible Withdrawable Circuit-Breaker Installation

Withdrawable circuit-breaker systems separate the removable breaker from a stationary fixed part. The fixed assembly provides the permanent interface with the switchboard, while the compatible circuit breaker can be withdrawn when inspection, testing, servicing or replacement is required.

The ABB 1SDA054756R1 provides this fixed interface for compatible three-pole Tmax T5 400 withdrawable circuit breakers. Its vertical rear terminal arrangement supports suitable rear-connected switchboard designs, making it a practical solution for low-voltage distribution systems where accessibility and maintainability are important.

Typical Applications

  • ABB Tmax T5 400 withdrawable circuit-breaker installations.
  • Industrial low-voltage switchboards.
  • Electrical distribution panels.
  • Manufacturing and process facilities.
  • Commercial and industrial power distribution systems.
  • Installations requiring removable circuit breakers for inspection, maintenance or replacement.
