Total Motor Protection Relay
Protect your most valuable investments!
The ECA500-11 is a series of micro-controlled 3-phase total motor protection current, voltage & power monitoring relays. They’re designed to protect electrical loads and motors from failure and damage due to common current and voltage faults.
The ECA500-11’s constantly supervise current and voltage values and when any harmful condition occurs, the output connection is deactivated until the fault disappears, power line conditions return to acceptable levels and the motor has cooled to an acceptable temperature level. Specific timing features such as Start Up Delay (TC) and Trip Delay (TD) are incorporated to prevent nuisance tripping due to rapid power fluctuations.
