Part of the MiCOM P40 platform, the MiCOMho Agile P443, P445 and P446 relays operate with advanced load blinding and disturbance detection techniques, such as power swing blocking, to ensure stability when no tripping is required. Whether protection is required for lines, cables or hybrids of grounded transmission and distribution circuits, the MiCOMho Agile P443, P445 and P446 relay characteristics allow for versatile deployment.

Key features:

• MiCOM P443 & P446: True subcycle distance protection with transmission class security and dependability
• Unparallelled speed, security and selectivity
• Extremely versatile logic capabilities, managing leader-follower auto-reclosing and check synch schemes in dual breaker applications
• Transmission-class circuit breaker failure protection for one or two breakers. The breaker failure protection may be initiated from internal protection within the relay or from external devices
• Single-pole and 3-pole breaker operation is supported, with independent supervision and condition monitoring statistics for each pole
• Trip circuit supervision, control and interlocking schemes can be designed via graphical support software
• No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
• NERC CIP cybersecurity
• Binary inputs ESI48-4 EB2 compliant
