1SDA101906R1 ABB XT7D 1000 3P Fixed Switch-Disconnector

Why Choose the ABB XT7D 1000 3P 1SDA101906R1 Switch-Disconnector?

The ABB 1SDA101906R1 is a SACE Tmax XT7D switch-disconnector designed for reliable isolation and switching in demanding low-voltage electrical distribution systems. Rated at 1000 A, this three-pole device provides a robust means of disconnecting electrical circuits for operational switching and safe isolation within industrial, commercial and infrastructure installations.

Unlike a circuit breaker equipped with an electronic protection release, the XT7D is configured as a moulded-case switch-disconnector. It is intended primarily for switching and isolation duties rather than automatic overload or short-circuit protection, so appropriate upstream or associated protective devices should be selected as required by the electrical installation.

The 1SDA101906R1 has a fixed three-pole configuration with front terminals and a lever operating mechanism. Its 1000 A operational rating applies to both AC-22A and AC-23A utilisation categories at 415/440 V AC and 690 V AC, making it a versatile isolation solution for high-current low-voltage distribution assemblies.

Key Advantages

• High-current 1000 A switch-disconnector for low-voltage distribution systems.
• Provides dependable switching and isolation of three-phase electrical circuits.
• Three-pole configuration for three-phase applications.
• Rated at 1000 A for AC-22A and AC-23A utilisation at 415/440 V AC and 690 V AC.
• Fixed construction simplifies integration into switchboards and distribution assemblies.
• Front terminals provide a practical main-circuit connection arrangement.
• Lever operating mechanism provides straightforward local operation.
• Part of ABB’s established SACE Tmax XT low-voltage platform.
• Suitable for high-current industrial, commercial and infrastructure isolation duties.

High-Current Switching and Electrical Isolation

The ABB XT7D 1000 is designed to provide controlled switching and isolation of high-current low-voltage circuits. Its 1000 A AC-22A and AC-23A operational ratings at both 415/440 V AC and 690 V AC make it suitable for demanding distribution and switching duties, while its 20 kA short-time withstand capability for 1 s supports use in robust electrical distribution architectures.

As a switch-disconnector, the 1SDA101906R1 should not be confused with an XT7 circuit breaker fitted with an Ekip protection trip unit. Its principal function is switching and isolation; overload and short-circuit protection must therefore be provided by appropriately selected protective equipment elsewhere in the electrical system where required.

Typical Applications

• Main low-voltage switchboards and distribution boards.
• High-current circuit isolation.
• Industrial electrical distribution systems.
• Commercial and infrastructure power installations.
• Manufacturing plants and process facilities.
• Incoming and outgoing distribution circuits.
• Machinery and plant isolation arrangements.
• Three-phase systems requiring a 1000 A fixed switch-disconnector.
