1SDA060344R1 ABB T6D 630 4P FF 630 A Switch-Disconnector

Why Choose the ABB T6D 630 4P FF 1SDA060344R1 Switch-Disconnector?

The ABB T6D 630 4P FF 1SDA060344R1 is a heavy-duty four-pole switch-disconnector designed for reliable switching and isolation in low-voltage industrial power distribution systems. As part of the established ABB SACE Tmax T6 series, it combines a 630 A rated uninterrupted current with a fixed four-pole construction for dependable isolation of three-phase systems incorporating a neutral conductor.

Unlike a moulded case circuit breaker equipped with an overcurrent protection release, the T6D is designed specifically for switching and disconnection. Its primary function is to isolate an electrical circuit, making it suitable for use as a main switch or isolating device within switchboards, distribution panels and industrial installations where the necessary overcurrent and short-circuit protection is provided separately.

The T6D 630 supports rated operational voltages up to 690 V AC and 750 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 8 kV. Its fixed four-pole configuration with front terminals provides straightforward integration into electrical distribution assemblies, while a rated short-time withstand current of 15 kA for 1 s supports demanding high-current installations.
