YCIS8-55 XPV Photovoltaic DC Isolation Switch

General
Isolating switch YCIS8 series is suitable for DC power systems with rated voltage
DC1500V and below and rated current 55A and below. This product is used for infrequent on/off, and can disconnect 1~4 MPPT lines at the same time. It is mainly used in control cabinets, distribution boxes, inverters and combiner boxes in photovoltaic power generation systems for isolation of DC power distribution systems. The external waterproof performance of this product reaches IP66. The inner core of the product can be installed inside the inverter for controlling the incoming line of the inverter.
Standards: IEC/EN60947-3, AS60947.3, UL508i standards.
Certification: TUV, CE, CB, SAA, UL, CCC.
