Solar Isolators

Product catalog summary
Overview
IMO specializes in control component technology for the renewable energy sector, particularly solar energy. Their products are engineered to meet stringent technical and commercial standards, ensuring safe DC switching and optimal solar energy conversion.
Product Range
  • AC Isolators: These are enclosed with an IP65 rating, available in 3 to 8 pole versions, and rated from 20A to 80A. They feature an interlocked enclosure lid and three padlockable positions for enhanced safety.
  • Mobile Connectors: Designed to connect PV panels in series and link cabling lengths, allowing for the connection to branch and panel connectors and enabling the switching of multiple strings with a single DC isolator.
  • Solar Isolators: Built for demanding DC disconnect applications, featuring an operator-independent trigger ratchet switching mechanism with switching times under 5ms. Available in 2 to 8 pole versions with various mounting and handle configurations.
  • Solar Relays: These meet high contact gap and insulation requirements, offering flexibility for demanding solar OEM applications.
Technical Features
  • True DC Switch: The IMO SI range is a genuine DC switch, not an AC version adapted for DC use. It includes a high-speed trigger ratchet switching mechanism, IP65 rated enclosure, knife edge contacts, and arc cooling chambers.
  • Connectors: Rated up to 1000V 30A for 2.5-6mm² cables, featuring a secure easy clip and release system, IP67 protection, UL94-5VA fire resistance, and class 2 protection.
Safety and Compliance
All photovoltaic installations must include DC isolators as per IEC 60364-7-712 standards. IMO products are designed to comply with these standards, ensuring safety and reliability in solar installations.
Specifications and Configurations
The document details specifications for various product configurations, including DC21B ratings, pole configurations, and mounting options. Products are available in multiple configurations to meet different installation needs.
Actuator Switches Overview
The document provides detailed specifications for various actuator switches, including rotary and lever types, with different mounting options and configurations. It includes information on current ratings, contact configurations, and physical dimensions.
Specifications
Switches are categorized by current ratings (16A, 25A, 32A, etc.) and voltage levels (600V to 1500V). Each switch type is associated with a specific part number and weight. The document specifies the number of poles in series and the number of strings for each configuration.
Product Types
The document covers several product types, including:
  • Plastic Enclosure Rotary Actuator Switches with IP65 and NEMA Type 1 ratings.
  • Panel Mounting Rotary Actuator Switches with IP66 and NEMA Type 3R ratings.
  • Lever Actuator Switches for single hole mounting with IP66 and NEMA Type 3R ratings.
  • Emergency Stop Rotary and Lever Actuator Switches with lockable off features.
Mounting and Installation
Switches are designed for various mounting options, including panel mounting, base mounting, and single hole mounting. Some switches feature adjustable shaft lengths and special extended shafts available upon request.
Environmental Ratings
Switches have different IP ratings (IP40, IP65, IP66) indicating their level of protection against dust and water ingress. NEMA ratings (Type 1, Type 3R) are also provided, indicating suitability for indoor or outdoor use.
Key Features
Many switches include lockable off positions for safety, and some are designed with door clutch mechanisms for enhanced security. The document also highlights the use of escutcheon plates and rotary handles for ease of operation.

Mobile connectors are used to connect PV panels in series. They also link lengths of cabling and allow connection to Branch and Panel connectors. Branch connectors are used to link multiple strings together allowing, for example, a 2 pole (single string) DC isolator to switch both strings at the same time. Panel connectors mount on solar string boxes, enclosed DC isolators and any other enclosed DC switching device allowing easy connection to the rest of the PV system. 1000V DC 30A Rated For 4-6mm² Cables Secure Easy Clip And Release System IP67 Protection UL94-5VA Fire Protection Class 2 Protection...
