Why Choose the ABB OTDC100GV11 DC Switch Disconnector?
The ABB OTDC100GV11 is a compact, high-performance 100 A two-pole DC switch disconnector engineered for reliable switching and electrical isolation at up to 1500 V DC. Part of ABB's OTDC S2.0 series, it is specifically designed for modern high-voltage DC installations including photovoltaic, energy-storage and industrial DC power systems.
The OTDC100GV11 uses a single-circuit, two-pole configuration with a front-operated mechanism positioned between the poles. The switch is supplied without a handle, shaft or other operating hardware, allowing compatible ABB operating accessories to be selected separately to suit the enclosure and installation.
With a rated operational current of 100 A at 1500 V DC for both DC-21B and DC-PV2 duties, the OTDC100GV11 provides dedicated performance for high-voltage DC switching. Its compact S2.0 frame, IP20 protection and lug terminals support efficient integration into space-conscious electrical assemblies.

Reliable 1500 V DC Switching and Electrical Isolation
The ABB OTDC100GV11 is purpose-designed for high-voltage direct-current circuits, providing a defined means of manually disconnecting equipment for operational switching, servicing and maintenance. Its 100 A, 1500 V DC capability and two-pole architecture make it particularly suitable for modern DC systems where compact, efficient isolation is required.
The front-operated mechanism between the poles and compact S2.0 frame simplify integration into electrical assemblies, while the separately selected handle and shaft allow the operating arrangement to be matched to the enclosure. Its DC-PV2 rating also makes the OTDC100GV11 well suited to photovoltaic switching applications.
Typical Applications
- Photovoltaic array and inverter DC isolation.
- Battery and energy-storage systems.
- 1500 V DC power distribution equipment.
- Renewable-energy power conversion systems.
- Industrial DC switchboards and electrical assemblies.
- High-voltage DC circuits requiring compact two-pole isolation.
