IMO SI32-PEL64R-8: 4-String Solar PV DC Disconnect Switch (32A) The IMO SI32-PEL64R-8 is a professional-grade True DC Isolator designed for high-capacity solar arrays. Featuring an 8-pole configuration, this switch allows you to safely disconnect up to four solar strings simultaneously. Engineered specifically for the solar industry, it sets the global benchmark for safety and reliability. True DC Safety & Performance Unlike standard AC-modified isolators, the IMO SI series features a dedicated operator-independent switching mechanism. This ensures a rapid break of the DC circuit with a guaranteed arc suppression time of less than 5ms (3ms typical), protecting your inverter and charge controller from dangerous electrical arcs. Key Product Features Quad-String Capacity: 8-pole design allows for independent isolation of 4 positive and 4 negative PV strings. NEMA 4X / IP66 Weatherproof: UV-resistant enclosure designed for the most extreme outdoor solar environments. Knife-Edge Contacts: Self-cleaning contacts ensure long-life operation and prevent overheating under high DC loads. Built-in Arc Chambers: Integrated cooling chambers keep the device stable during repeated manual operations. Safety Lockable Handle: Rotary handle can be locked in the "OFF" position to comply with maintenance safety protocols.
