Safety device used on the motor occurs when the load is called the Thermal Over Load Relay (TOR \/ TOL) is usually coupled with a contactor, the market there is also a more integrated security burden on Motor Circuit Breaker.<\/span> Relay is normally connected to the contactor to the main contact 2, 4, and 6 before being connected to the load (motor).<\/span> Useful to provide protection against the motor from damage due to overload.<\/span><\/p>\n

Some causes of overload are:<\/span><\/p>\n

\n
• Too magnitude of mechanical load on the motor.<\/span><\/li>\n
• Starting current is too large or the motor stops suddenly.<\/span><\/li>\n
• The opening of one phase of a 3-phase motors.<\/span><\/li>\n<\/ul>\n

  Currents that are too big arise on the motor load will flow to the motor windings which can cause damage and burning of motor windings.<\/span> To avoid this happening mounted Thermal Over Load Relay (TOR \/ TOL) in the control circuit.<\/span> The working principle Thermal Over Load Relay (TOR \/ TOL) by heat (temperatures) generated by the current GCC flowing through the heating elements bimetal, which menakibatkan bimetal curving will then move contacts mechanical circuit breaker electrical contacts 95-96 open and contacts 97-98 closes.<\/span>

  Other equipment from thermal overload is a mechanical reset function to restore the contact position 95-96 in its original position (connect in normal circumstances) and contact 97-98 (open under normal circumstances).<\/span> After the reset button is pressed, the contacts 95-96 which was originally opened as a result of the load will re-close and contact 97-98 will be re-opened.<\/span> Another part of the thermal overload is the current limit regulator.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
