P3U30-6AAA1BBAA
Perfectly suited for buildings and industry, utilities, and large industrial processes. The relay include protection for overcurrent, overload, broken conductor, earth-fault and breaker failure as per ANSI. It also feature an automatic recloser, a switch ON to fault, inrush protection and lockout among others. Simple, reliable, safe and easy-to-use, thanks to the User Interface display. The protection relay can to be supplied by a 48 VAC/VDC to 230 VAC/VDC network. It include 16 digital inputs, 1 RS485 communication port and 1 USB on front of the device. Mechanical dimensions are 169.5 mm in height, 170 mm in width and 205 mm in depth. The relays are certified with EN 60255-26 for electromagnetic compatiblity. The device is compatible with aditional modules and accessories: connection cables, communication modules, temperature and analogue input and output modules, LPVT & PLCT option, arc flash sensors, and other accessories.
