ABB OTDC400FV02 2-pole DC switch disconnector rated at 400 A and 1500 V DC for utility-scale photovoltaic systems, inverter equipment and industrial DC isolation.
£860.32
The ABB 1SCA158200R1001, also known as the OTDC400FV02, is a fully optimised 2-pole DC switch disconnector developed for utility-scale photovoltaic installations and other demanding high-voltage direct current systems. Rated at 400 A and 1500 V DC, it provides reliable load switching and secure electrical isolation for modern renewable energy equipment.
ABB's two-pole 1500 V DC design helps improve system efficiency by reducing switch losses by up to 35% compared with conventional solutions. Its compact construction can also occupy up to 30% less space, helping panel builders and equipment manufacturers create smaller combiner boxes, inverter assemblies and DC distribution enclosures.
The OTDC400FV02 features a front-operated mechanism positioned at the end of the switch and a single-circuit 2a, 2b configuration. It is supplied without an external operating handle or shaft, allowing compatible ABB accessories to be selected according to the enclosure depth and installation requirements.
Utility-scale solar installations increasingly use 1500 V DC architectures to reduce cabling requirements and improve overall system efficiency. Switching equipment used in these systems must provide dependable isolation while controlling conduction losses, heat generation and enclosure space.
The ABB OTDC400FV02 combines a high current rating with compact dimensions and an optimised two-pole design. This makes it particularly suitable for photovoltaic equipment manufacturers and panel builders requiring reliable high-voltage DC isolation without unnecessarily increasing enclosure size.
