1SDA101909R1 ABB XT7D 1000 4-Pole Fixed Switch-Disconnector

Why Choose the ABB XT7D 1000 1SDA101909R1 Switch-Disconnector?

The ABB 1SDA101909R1 is a SACE Tmax XT7D 1000 switch-disconnector designed for dependable switching and isolation of high-current low-voltage circuits. Rated at 1000 A, this four-pole device combines the robust ABB Tmax XT7 platform with a fixed installation format, front terminals and a lever operating mechanism for straightforward integration into power-distribution assemblies.

Configured as a moulded case switch / switch-disconnector, the XT7D is intended primarily for circuit switching and isolation rather than overload and short-circuit protection through an integrated trip release. It is therefore well suited to installations where the required overcurrent protection is provided by separate protective devices elsewhere in the electrical system.

The 1SDA101909R1 carries 1000 A in both AC-22A and AC-23A utilisation categories at 415/440 V AC and 690 V AC. A rated short-time withstand current of 20 kA, rated insulation voltage of 1000 V and rated impulse withstand voltage of 8 kV make it a robust isolation solution for demanding industrial and infrastructure power-distribution applications.

Key Advantages

• High-current 1000 A switch-disconnector for demanding low-voltage installations.
• Provides reliable switching and circuit isolation in main and sub-distribution systems.

Reliable High-Current Switching and Isolation

The ABB XT7D 1000 provides a dedicated solution for installations requiring dependable high-current switching and isolation without an integrated overload or short-circuit protection release. Its 1000 A AC-22A and AC-23A ratings support demanding distribution duties, while the four-pole arrangement enables simultaneous switching within three-phase systems incorporating a neutral conductor.

With its 20 kA short-time withstand current, 1000 V insulation rating, fixed construction and front bolt connections, the 1SDA101909R1 is engineered for integration into substantial low-voltage switchboards. Optional motorised operation further allows the XT7D platform to be adapted for applications requiring remote or automated switching.

Typical Applications

• Main switch and isolation duties in low-voltage switchboards.
• Industrial power-distribution systems.
• Main distribution boards and sub-distribution assemblies.
• Transformer and generator distribution circuits.
• Manufacturing and process-industry installations.
• Commercial buildings and critical infrastructure.
• High-current circuits where overcurrent protection is provided separately.
