IsoMate – Earth Leakage Monitor

L11JØ2Ø1 IsoMate HV Off-line Lookahead Earth Leakage Monitor 

IsoMate is an off-line leakage (isolation) monitor which helps protect motors and equipment against damage.

It can measure leakage current of a 3-phase load such as AC motors and transformers.

L11JØ3Ø1 IsoMate HV On-line Core CT Earth Leakage Monitor

IsoMate is an on-line earth leakage (isolation) monitor with self-test which helps protect motors and equipment against damage.

It can measure leakage current of a 3-phase load such as AC motors and transformers, while the motor is running using an external Core Balanced CT.
