1SDA060387R1 ABB T6 W FP 4P EF Withdrawable Circuit Breaker Fixed Part

Why Choose the ABB T6 W FP 4P EF 1SDA060387R1 Fixed Part?

The ABB T6 W FP 4P EF 1SDA060387R1 is a four-pole fixed part for withdrawable SACE Tmax T6 circuit breakers. Designed for the T6 withdrawable system, it forms the stationary base into which the compatible moving part of the circuit breaker is installed, providing a robust interface between the breaker and the switchboard.

This fixed part is designed for T6 630 and T6 800 frame applications and supports a rated uninterrupted current of up to 800 A. Its four-pole construction makes it suitable for compatible three-phase four-wire distribution arrangements, while the withdrawable architecture allows the circuit breaker moving part to be removed from the fixed base when required for maintenance, replacement or system management.

The EF configuration incorporates extended front terminals for the main circuit connections. The assembly uses bolted main-circuit connections and is designed for ABB Tmax T6 systems with rated operational voltages up to 690 V AC and 750 V DC, providing a practical fixed base for high-current industrial switchboards and distribution assemblies.

Reliable Fixed Base for Withdrawable Tmax T6 Circuit Breakers

A withdrawable circuit-breaker system separates the installation into a stationary fixed part and a removable moving part. The ABB T6 W FP 4P EF remains installed within the switchboard and provides the main electrical interface for the compatible T6 moving assembly. This arrangement can simplify maintenance because the circuit breaker can be withdrawn without removing the permanently installed fixed base and its associated switchboard connections.

With its four-pole design, 800 A current capability and extended front terminals, the 1SDA060387R1 is suited to substantial industrial distribution systems using compatible ABB Tmax T6 withdrawable circuit breakers. It should be combined with the appropriate ABB moving-part conversion components and circuit breaker for the required T6 withdrawable configuration.

Typical Applications

• ABB SACE Tmax T6 withdrawable circuit-breaker installations.
• Industrial low-voltage switchboards.
• Main and sub-main power distribution panels.
• Three-phase four-wire distribution systems.
• Manufacturing and process plant switchgear.
• High-current industrial feeder assemblies.
• Installations requiring removable or serviceable circuit-breaker arrangements.
