Carlo Gavazzi Monitoring Relay 3-Phase Load Guard, 0-0.9 Cos Ø, Plug-In, SPDT, Supply: 415VAC.
3-phase load guard monitoring plug-in relay. Measures the phase difference between motor current and voltage. Often used for protecting a motor from overload in applications where stops can damage the whole mechanical system.
General Characteristics
Load guard for asynchronous motors and other symmetrical loads.
Measures on phase difference (cos j) between motor current and voltage.
Measuring range: Cos Ø = 0-0.9 with 1-phase current metering transformer, type MI...
