The Easergy P5 is Schneider Electric's withdrawable protective relay for demanding medium voltage distribution applications. This feeder relay offers withdrawable design with backup memory function enabling industry-leading 10 minute recovery time. It provides redundant Ethernet including IEC 61850 as well as plug and play communication modules that can evolve with your application. Easergy P5 offers safety, security, and connectivity built on more than 100

years of experience in protection relays. The Easergy P5 protection relay can be applied to all types of MV distribution networks. It can be supplied with 48 to 250 VDC and 100 to 230 VAC. It works with conventional CTs/VTs. 3 phase current inputs, 1 standard neutral current input, 1 sensitive neutral current input and 4 voltage inputs. It offers 10 digital inputs and 8 digital outputs and no communications. Communication modules can be added any time. The product dimensions are 180 mm in height (7.09 in), 152,4 mm in width (6.00 in) and 224 mm in depth 8.82 in) for a net weight of 3.5 kg (7.7 lbs). Easergy P5 is compliant with EN 60255-26, EN 60255-27 standards and with UL Standard. It provides Marine certification. This product can be flush mounted on the panel or in the rack.
