£1,849.04
The ABB OTDC630F22 (SKU 1SCA158306R1001) is a heavy-duty DC switch disconnector engineered for the safe isolation of high-current direct current circuits in utility-scale photovoltaic (PV) installations, battery energy storage systems (BESS) and industrial DC applications. As part of ABB's advanced OTDC switch disconnector range, it delivers exceptional switching performance, reduced power losses and a compact design for demanding renewable energy systems.
Designed for 1000 V DC utility-scale solar applications, the OTDC630F22 features a 4-pole double-circuit (4a / 4c) configuration that enables safe isolation of two PV strings within a single compact device. Its optimised design helps reduce the size of combiner boxes and inverter assemblies while improving overall system efficiency. Phase barriers are supplied as standard, while operating handles and shafts are ordered separately.
With a 630 A rated operational current (DC-21B), robust construction and compliance with IEC 60947-1 and IEC 60947-3, the OTDC630F22 delivers dependable DC isolation for renewable energy infrastructure and industrial power systems.
The ABB OTDC630F22 has been developed specifically for modern utility-scale photovoltaic installations where high current capacity, compact dimensions and dependable switching performance are essential. Its four-pole double-circuit architecture enables engineers to reduce combiner box and inverter sizes while maintaining safe DC isolation and high operational efficiency.
As part of ABB's latest OTDC M-Series, the OTDC630F22 provides excellent electrical endurance, reduced switch losses and dependable long-term operation, making it an ideal choice for renewable energy developers, OEM panel builders and industrial DC system integrators.
