The SOURCE1 icm517a is a NEMA Type 4X enclosed Type 2 Surge Protective Device built to protect single-phase electrical equipment from damaging voltage spikes and transient power surges. This surge protector operates on 120 and 240 volt AC systems and delivers 100KA surge current capacity with 1020 joules of surge energy absorption. It is designed for use by HVAC technicians, electricians, refrigeration mechanics, and other trade professionals who need reliable overvoltage protection in demanding environments. The NEMA Type 4X enclosure provides protection against dust, debris, and moisture, making it suitable for both indoor and outdoor installations. The Type 2 classification means this device is installed downstream of the main service entrance, typically at sub-panels, disconnect boxes, or at the equipment level. This placement provides point-of-use protection where it matters most. Common applications include air conditioning systems, heat pumps, refrigeration units, motors, compressors, appliances, and sensitive electronics. Transient voltage surges can originate from lightning strikes, utility switching events, and load switching within a building. These surges can degrade or destroy motors, control boards, variable frequency drives, and electronic components over time. Installing a properly rated surge protective device like the SOURCE1 icm517a helps extend the service life of equipment and reduces costly unplanned downtime. The 100KA surge current rating indicates the device can handle very high peak surge currents, meeting the demands of commercial and residential HVAC and refrigeration installations. The 1020 joule energy rating reflects the total surge energy the device can absorb. This unit is a practical choice for new installations, retrofits, and service replacements where equipment protection and long-term reliability are priorities.
The SOURCE1 icm517a delivers reliable transient surge protection for single-phase HVAC, refrigeration, and electrical equipment in a durable NEMA Type 4X enclosure. Its 100KA surge current capacity and 1020 joule rating make it well suited for residential and light commercial applications.
