Part of the MiCOM P40 platform, the Agile P543, P544, P545 & P546 range of transmission-class protection relays provide comprehensive line protection for differential, subcycle distance and directional earth fault applications, with 1/3 pole tripping. This range of products is ideal for HV, EHV and UHV applications on lines and cables of any length.

Key features:

• Current transformer supervision operates with or without voltage inputs, to prevent any spurious tripping and raise the alarm
• True subcycle distance protection with transmission class security and dependability 
• Unparallelled speed, security and selectivity 
• Compatible with 56/64kbps or 2Mbps for direct fiber or MUX communications channels
• Suitable for use with equal or unequal transmit and receive path delays (eg SDH/SONET)
• Suitable for MPLS differential channels
• Full suite of monitoring, control and recording capabilities plus fault locator, autoreclose and check synchronism
• Harsh environment coating as standard for all GE’s MiCOM P540 series relays protects against corrosive gases such as H₂S or SO₂
• 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
