Easergy P1 ( Formerly known as Vamp 11F )

Easergy P1 is a basic numerical relay that provides reliable and effective overcurrent protection with automation, control and measurement functions. It may be applied to all low voltage or medium voltage applications as a primary or back-up protection device.

Model L/L+: Basic phase and earth fault current protection with fault recording and two setting groups.
With only 4 relay output contacts and circuit breaker control keys.

Model N: Communicating device with basic phase overcurrent and earth fault protection. It provides thermal overload function, fault and events recording and two setting groups. It comprises 6 relay outputs, a front USB and rear RS485 communication port.

Model B: Standard protection relay with phase overcurrent, earth fault protection and communication. It provides switch on to fault and blocking logic functions, event and fault recording and two setting groups. It comprises 4 relay outputs and 4 binary inputs, a front USB and rear RS485 communication port. Circuit breaker control is effected by front panel keys, remote
communication port or via binary input.

Model A: Advanced model with phase overcurrent and earth fault protection. Covering all features of model B, it’s comprises additionally inrush blocking function and in-built circuit breaker and trip circuit supervision. Moreover it can store 4 sec of disturbance records. CB control can be realized via front panel keys, remotely thru communication port or via binary input. This
model offers a unique functionality of powering HMI board via USB front port. It means that setting and data downloading can be done without auxiliary voltage presence. Having 4 binary inputs and 8 relays outputs it can be applied to more advanced schemes within utilities or industrial sites as feeder, incomer or transformer protection.

Model E: It’s a highest model in Easergy P1F range. Covering all features of model A it comprises 8 binary inputs and 6 output relays. This relay can meet the requirements of more advanced applications in medium and low voltage substation. Additionally,in-built negative sequence overcurrent protection, broken conductor detection and 4 shot auto-reclose function makes Easergy P1F suitable as a feeder protection of overhead lines.
