ABB has introduced its range of compact OTDC switch disconnectors for DC applications up to 1500 A with switches featuring 2-pole configuration for 1000 VDC per polarity. The switches have been designed to support the solar industry’s path towards higher voltages and greater efficiency.
The devices are suitable for disconnecting a solar inverter from the DC side and can be used in combiner boxes for switching of individual PV arrays. For installations with more than one circuit, the device allows control of two or three circuits simultaneously with only one switch.
With the existing OTDC switches and ABB connection kits, it is possible to use a tested solution to create outputs of up to 1500 A (IEC) and 800 A (UL), achieving up to 37% more compact space.
