Why Choose the ABB T6D 800 1SDA060346R1 Switch-Disconnector?
The ABB 1SDA060346R1 is a Tmax T6D 800 four-pole switch-disconnector designed for reliable switching and isolation in low-voltage industrial and commercial power distribution systems. As part of the ABB SACE Tmax T4–T8 range, it provides an 800 A current rating in the robust T6 frame for applications requiring dependable high-current circuit isolation.
This T6D 800 is supplied in a fixed four-pole configuration with front terminals. Its four-pole arrangement enables simultaneous switching of three phase conductors and a neutral conductor where required, making it suitable for four-wire three-phase distribution systems and switchboards requiring complete circuit isolation.
Unlike a Tmax MCCB equipped with a thermomagnetic or electronic protection release, the T6D is a switch-disconnector intended primarily for switching and isolation. The appropriate overload and short-circuit protective devices should therefore be selected separately as part of the overall electrical protection system.

What Does an ABB Tmax T6D Switch-Disconnector Do?
A switch-disconnector provides a means of making, breaking and isolating an electrical circuit without incorporating the automatic overload and short-circuit protection associated with a circuit breaker. It is commonly used as a main switch, feeder isolator or local isolation device where a clearly defined means of disconnecting equipment or a section of an electrical installation is required.
The ABB T6D 800 uses the proven Tmax T6 platform to provide high-current four-pole switching in a compact moulded-case format. The four-pole configuration makes the 1SDA060346R1 particularly useful in three-phase four-wire systems where the neutral conductor must also be switched, while separate protective devices provide the required fault and overload protection.
Typical Applications
- Main switch and incoming supply isolation.
- Industrial low-voltage distribution switchboards.
- Three-phase four-wire systems requiring neutral isolation.
- High-current feeder and sub-main isolation.
- Machinery and industrial process electrical isolation.
- Commercial and infrastructure distribution systems requiring an 800 A four-pole isolating device.

Frequently Asked Questions
What is the ABB 1SDA060346R1?
The ABB 1SDA060346R1 is a Tmax T6D 800 four-pole switch-disconnector in fixed execution with front terminals, designed for switching and isolation in low-voltage power distribution systems.
What is the current rating of the ABB 1SDA060346R1?
The ABB T6D 800 has a rated current of 800 A, making it suitable for high-current industrial and commercial distribution applications.
Is the ABB T6D 800 a circuit breaker?
The T6D 800 is a switch-disconnector rather than an automatic overcurrent circuit breaker. Its primary functions are switching and isolation, so suitable overload and short-circuit protection should be provided elsewhere in the electrical system.
Why does the ABB 1SDA060346R1 have four poles?
The four-pole configuration allows the device to switch four conductors and is particularly suitable for three-phase four-wire systems where the neutral conductor also needs to be switched and isolated.
What does 4P F F mean on the ABB T6D 800?
The designation identifies a four-pole device in fixed execution with front terminals, suitable for permanent installation in compatible electrical switchboards and distribution assemblies.
Trusted ABB Switching and Isolation
ABB SACE Tmax switch-disconnectors provide robust switching and isolation for industrial and commercial low-voltage distribution systems, with the T6D 800 offering dependable 800 A four-pole operation for applications requiring simultaneous isolation of phase and neutral conductors.
