IMO DC Disconnect Rooftop Isolator Switch

The IMO SI32-PEL64R-4 / SI32-PEL64R-2 DC Disconnect is a rotary actuator switch designed for safe, lockable disconnection of DC/AC inverters from photovoltaic panels. Engineered as a true DC isolator, it complies with IEC 60364-7-712 requirements for PV installations. Unlike AC switches adapted for DC, this isolator is built specifically for DC operation, ensuring maximum safety and reliability.

Key Features:

• True DC switch, not an AC-adapted version
• Operator-independent switching mechanism with high-speed ratchet trigger
• IP66-rated, self-extinguishing plastic enclosure
• Knife-edge contacts with arc cooling chambers
• Compact, space-saving design with 16 mm² box terminals
• Lockable off safe-lock for added security
• Rated thermal current: 32 A
• Rated insulation voltage: 1000 V, suitable for overvoltage I–III, pollution degree 3, Uimp=8 kV
• Contact distance per pole: 8 mm, 2 poles in series
• M25 cable gland entry option
• NEMA 3R, operating temperature: -40 °C to 45 °C
• Certified: UL508i (E362605), UL508 cRUus (E146487), CE, TUV, GOST, IEC CB
