The IMO SI32-PEL64R-4 Rooftop Isolator Switch from IMO Precision Controls stands out as a dedicated True DC isolator, designed specifically to disconnect DC/AC inverters from photovoltaic panels in solar installations. This essential safety component meets the stringent requirements of IEC 60364-7-712, ensuring that all photovoltaic systems are equipped with DC isolators.

Uniquely engineered as a True DC switch, the IMO SI avoids the pitfalls of AC switches that have been adapted for DC use. It features an operator-independent switching mechanism, which ensures reliable operation through high-speed trigger ratchet switching. The switch is housed in an IP66-rated, self-extinguishing plastic enclosure that offers protection against dust and water ingress, enhancing its durability and safety.

FEATURES:

• Knife-edge contacts and arc cooling chambers designed to enhance the switch’s electrical longevity and safety.
• A maximum torque of 1Nm allows for effortless operation.
• The compact design saves space while providing easy access for wiring through 16mm² box terminals.
• The switch provides a lockable off position with a safe-lock feature for secure maintenance and service.

TECHNICAL SPECIFICATIONS:

• Rated thermal current: 32A
• Rated insulation voltage: 1000V, suitable for overvoltage categories I to III and pollution degree 3, with Uimp=8KV.
• Contact separation per pole: 8mm, with 2 poles in series and support for 2 strings.
• Cable entry options include an M25 cable gland.
• Certifications include: UL508i (file number E362605), UL508 cRUus (file number E146487), CE, TUV, GOST, and IEC CB, reflecting its compliance with global safety standards.
• Operational temperature range: From -40°C to 45°C.

This IMO DC Disconnect Switch ensures robust performance and safety for your photovoltaic system, making it an ideal choice for reliable energy management.
