The IMO DC Disconnect Rooftop Isolator Switch provides safe, reliable isolation of photovoltaic arrays from the inverter during maintenance or emergency shutdowns. Designed specifically for solar applications, this true DC isolator enables rapid disconnection on the DC side of the system. Its compact IP67 / NEMA 4X rated enclosure, high-speed switching mechanism, and lockable OFF position ensure durable performance and secure system isolation in outdoor environments.

Key Benefits:

• Fast DC Shutdown: Quickly disconnects photovoltaic panels from the inverter, allowing for safe maintenance and emergency system isolation.
• True DC Isolator Design: Specifically engineered for photovoltaic systems to safely interrupt high-voltage DC circuits.
• Supports Two PV Strings: 4-pole configuration allows isolation of two PV strings, making it suitable for common rooftop solar installations.
• Secure Lockable Operation: Lockable OFF position and an 8mm contact gap per pole help ensure safe servicing and system protection.
• High-Speed Switching Mechanism: Operator-independent ratchet trigger mechanism delivers consistent and reliable DC disconnection.
• Weather-Resistant Enclosure: Rugged IP67 / NEMA 4X rated housing protects the switch from dust, water, and harsh outdoor conditions.
  

Use Cases:

The IMO DC Rooftop Isolator Switch provides a safe disconnect point between photovoltaic arrays and the inverter, allowing installers to isolate the system for maintenance, troubleshooting, or emergency shutdown.
