The PNM 3U Rack Dummy Circuit Breaker is a testing solution designed for Digital Relays devices. With its ESSAILEC connections, intuitive touchscreen interface and multi-manufacturer compatibility (48V \/ 127V), it can accurately simulate all the operating conditions of a high-voltage dummy circuit breaker: motor reset, SF6 thresholds, plugging\/unplugging, non-complementarity, Buchholz faults, etc. <\/p>\n

The product is designed to fit easily into a 19-inch rack, with quick access to functions via HMI and physical buttons. <\/p>\n

Shock-resistant (up to 5g), it features robust Schroff mechanics and an STM32 microcontroller for reliability and performance.<\/p>\n
