Why Choose the ABB T7-X1 W FP 4P EF-HR 1SDA062051R1 Fixed Part?
The ABB 1SDA062051R1 is a four-pole fixed part for withdrawable ABB Tmax T7 and Emax X1 circuit breakers, designed to provide the stationary power connection interface within high-current low-voltage switchboards. Identified as T7-X1 W FP 4P EF-HR, it combines a robust withdrawable architecture with a mixed terminal arrangement for flexible switchboard integration.
As part of the ABB Tmax T4–T8 accessory range, this fixed part has a rated uninterrupted current of 1600 A and a rated operational voltage of 690 V AC. Its four-pole construction supports compatible four-pole circuit breakers and is well suited to three-phase distribution systems where switching of the neutral conductor is required.
The EF-HR terminal configuration provides upper extended front terminals and lower rear flat horizontal terminals. This mixed connection arrangement offers flexibility for busbar and conductor routing while the withdrawable design allows the compatible circuit breaker to be removed for inspection, servicing or replacement without disturbing the fixed power connections.
Key Advantages
- Dedicated fixed part for withdrawable Tmax T7 and Emax X1 circuit breakers.
- 1600 A rated uninterrupted current for high-current power distribution systems.
- Four-pole configuration suitable for compatible four-pole circuit-breaker installations.
- 690 V AC rated operational voltage for industrial low-voltage applications.
- Mixed EF-HR terminal arrangement provides flexible switchboard connection options.
- Withdrawable architecture facilitates circuit-breaker inspection, maintenance and replacement.
Key Features
- ABB T7-X1 W FP 4P EF-HR fixed part.
- 1600 A rated uninterrupted current (Iu).
- 690 V AC rated operational voltage.
- Four-pole construction.
- Designed for withdrawable circuit-breaker installations.

Flexible Integration for Withdrawable Circuit Breakers
A fixed part forms the stationary connection section of a withdrawable circuit-breaker installation. It remains permanently connected to the switchboard while the compatible circuit breaker can be inserted, withdrawn or removed, supporting easier inspection and maintenance without requiring the main power conductors to be disconnected.
The ABB 1SDA062051R1 combines a high 1600 A current rating with an EF-HR terminal arrangement. Upper extended front connections and lower rear horizontal connections provide useful installation flexibility where incoming and outgoing busbars or conductors require different connection orientations within the switchboard.
Typical Applications
- Industrial low-voltage switchboards.
- Withdrawable ABB Tmax T7 circuit-breaker installations.
- ABB Emax X1 power distribution assemblies.
- Main and sub-main electrical distribution systems.
- Industrial and commercial high-current distribution panels.
- OEM switchgear and power distribution assemblies.
