The Megger SPI225 is a compact, high-current primary injection test system delivering up to 2000 A for testing circuit breakers, motor overloads, current transformers, and relays. It features automatic current regulation, DC offset elimination, and zero-crossing output for precise testing, with support for long/short time pick-up, timing, instantaneous pick-up, and ground fault timing.
The system allows parallel/series operation (up to 4 units, 362.8 A at 120 V, 242.9 A at 240 V with 10 ft leads) and is designed for switchgear commissioning and ground grid testing. The Smart Touch View Interface (STVI) touchscreen enables intuitive manual or automatic testing, while SPI software, integrated with thousands of breaker TCC curves and PowerDB, supports automated testing and report generation without a PC for manual tests.
Housed in a rugged enclosure with fuse, circuit breaker, and temperature sensor protection, it includes an emergency stop button, accessory carry case, power cord, and Ethernet cable, with optional Bluetooth. No warranty is specified, making it ideal for reliable, high-current testing in field and substation environments.
