IMO DC Disconnect Rooftop Isolator Switch (SI32-PEL64R-4)

The IMO SI32-PEL64R-4 is a true DC rotary isolator switch — not an AC switch de-rated or rewired for DC use — purpose-built to safely disconnect a DC/AC inverter from photovoltaic panels. Every PV installation needs a DC isolator per IEC 60364-7-712, and this one is housed in a lockable, weatherproof plastic enclosure with an operator-independent switching mechanism and high-speed trigger ratchet action for a clean, arc-free break every time.

Key Specs:

• Rated Thermal Current: 32A
• Rated Insulation Voltage: 1000V (overvoltage category I-III, pollution degree 3, Uimp=8kV)
• Contact Gap: 8mm per pole
• Configuration: 2 poles in series, 2 strings
• Enclosure Rating: NEMA 3R, IP66
• Operating Temperature: -40°C to 45°C
• Cable Entry: M25 gland, 16mm² box terminals
• Certifications: UL508i (E362605), UL508 cRUus (E146487), CE, TÜV, GOST, IEC CB

Features a lockable off "safe-lock" position, self-extinguishing plastic enclosure, and knife-edge contacts with arc cooling chambers for maximum safety during switching — everything you need to meet code on a rooftop PV disconnect.
