Why Choose the ABB 1SDA103794R1 XT7H-D 1200 Switch-Disconnector?
The ABB 1SDA103794R1 is a high-performance 3-pole moulded case switch-disconnector from the ABB SACE Tmax XT7 range, designed for switching and isolation duties in demanding low-voltage AC power distribution systems. Configured as an XT7H-D 1200 MCS, it provides a 1200 A rated uninterrupted current in a robust fixed installation format.
Unlike an automatic circuit breaker equipped with an overcurrent trip unit, this model is an MCS (Moulded Case Switch) intended primarily for circuit switching and isolation. It provides the familiar compact construction and switching platform of the Tmax XT7 family while allowing overcurrent protection to be provided by appropriately coordinated protective devices elsewhere in the electrical system.
The 1SDA103794R1 is supplied as a fixed, three-pole unit with front terminals and a lever operating mechanism. Designed for UL/CSA applications, the XT7H-D has an H performance level rated 65 kA at 480 V AC and an operational voltage of up to 600 V AC, making it suitable for high-current industrial and commercial distribution assemblies.

High-Current Switching and Isolation
A moulded case switch-disconnector provides a means of switching and isolating an electrical circuit without incorporating the automatic overcurrent protection functions associated with a conventional circuit breaker trip unit. This makes an MCS suitable for applications where switching and isolation are required while overload and short-circuit protection are provided by appropriately coordinated protective equipment elsewhere in the system.
The ABB XT7H-D 1200 MCS combines a 1200 A current rating with three-pole construction, fixed mounting, front terminals and a lever operating mechanism. Its compact Tmax XT7 platform makes the 1SDA103794R1 particularly suitable for high-current switchboards and distribution assemblies requiring dependable manual switching and circuit isolation.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main electrical switchboards and distribution panels.
- High-current feeder switching and isolation.
- Commercial and infrastructure power distribution.
- Industrial machinery and manufacturing facilities.
- Three-phase circuits requiring a 1200 A moulded case switch.
- UL/CSA electrical distribution applications.
