ABB OTDC315F33 315 A, 1000 V DC switch disconnector with 6-pole triple-circuit configuration for photovoltaic, battery energy storage and industrial DC isolation.
The ABB OTDC315F33 (SKU 1SCA158286R1001) is a high-performance DC switch disconnector designed for the safe isolation of 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 provides exceptional switching performance, compact dimensions and long-term reliability for demanding renewable energy systems.
Designed for 1000 V DC applications, the OTDC315F33 features a 6-pole triple-circuit (7a / 7e) configuration, allowing three independent PV strings to be isolated within a single compact switch. This innovative design reduces enclosure size while simplifying combiner box and inverter layouts. Phase barriers are supplied as standard, while operating handles and shafts are ordered separately.
With a 315 A rated operational current, 1500 V insulation voltage and compliance with IEC 60947-1 and IEC 60947-3, the OTDC315F33 delivers dependable DC isolation for modern photovoltaic power systems and industrial DC installations.
The ABB OTDC315F33 has been specifically developed for modern photovoltaic installations where multiple DC strings require safe isolation within a compact footprint. Its six-pole, triple-circuit architecture enables engineers to simplify combiner box layouts while maintaining dependable switching performance and excellent electrical endurance.
As part of ABB's latest OTDC M-Series, the OTDC315F33 delivers reduced switch losses, dependable long-term operation and simplified installation, making it an ideal solution for renewable energy developers, OEM panel builders and industrial DC system integrators.
