| This solid state overload monitor
protects against premature motor winding failure caused by overload,
phase loss, current unbalance, phase reversal and short cycling. Other
features are fast trip delay on phase loss, switch selectable manual
reset or automatic restart with delay; remote reset by removing input
voltage, and a random start delay after a power outage (auto restart
only). Connecting a DC voltmeter to the meter terminals allows for
accurate setting of full load current over a wide 4:1 range or manual
adjustable settings. Two LED indicators display output status, faults,
and delays in progress. The ESTM series provides the protection of
a voltage monitor and a motor overload, and can be used with most
three phase motor Contactors. |
