Product Overview
The Photovoltaic Isolator Switch is a dedicated DC disconnect switch designed for safe isolation of photovoltaic power circuits. It is suitable for DC systems up to 1200V with rated current up to 32A, allowing secure disconnection of one or two MPPT lines simultaneously.
This isolator switch is primarily used in solar PV control cabinets, distribution boxes, and combiner boxes, ensuring reliable isolation during maintenance, inspection, or emergency shutdown of DC circuits. The IP66 waterproof enclosure makes it suitable for outdoor and harsh environmental conditions commonly found in photovoltaic installations.
