Why Choose the ABB T7-X1 W FP 4P HR-EF 1SDA062050R1 Fixed Part?
The ABB 1SDA062050R1 is a four-pole fixed part for withdrawable ABB Tmax T7 and Emax X1 circuit breakers, designed for integration into high-current low-voltage switchboards and power distribution assemblies. Identified as T7-X1 W FP 4P HR-EF, it provides the stationary connection interface required for compatible withdrawable circuit-breaker installations.
As part of the ABB Tmax T4–T8 accessory range, this fixed part is rated for an uninterrupted current of 1600 A and an operational voltage of 690 V AC. Its four-pole construction makes it suitable for three-phase distribution systems requiring a switched neutral, while the withdrawable architecture supports circuit-breaker removal for inspection, servicing or replacement.
The HR-EF terminal configuration combines upper rear horizontal terminals with lower extended front terminals. This mixed connection arrangement provides flexibility when routing busbars and conductors within switchboards, making the 1SDA062050R1 particularly useful in installations where upper and lower power connections require different orientations.
