Applies electronic braking to the motor when the switch is in the park position which helps prevent damage to the controller in the event of accidentally switching directions when the. Has no-load rated make or break contacts so it needs to be used with a speed controller and the vehicle should be stopped before switching between forward, park, and reverse directions. When overload occur circuit breaker opens Q1 so the motor is stopped. 48 Volt 150 Amp Motor Reversing Contactor 48 Volt DC 150 Amp motor reversing contactor.
In a similar manner things take place if we want to change the direction of rotation, thereby pressing Reverse button contactor Q3 is connected so the motor is rotating counterclockwise, this is possible only by activating previously the Stop button. By pressing Forward push button the Q2 coil contactor is energized the motor will be connected for clockwise run and maintains itself after the button Reverse by means of auxiliary switch Q2, the Stop button and the auxiliary contact of Q3, which serves as interlock, thus avoiding simultaneous connection of Q2 and Q3 contactors.
#FORWARD AND REVERSE MOTOR CONTACTORS SERIES#
Siemens Motor Starter Contactors - Series 3TF8 3TF8. Mechanincally interlocked, it reduces panel space by 50 over conventional reversing contactors. Operating mode: Same as for direct on line starting instead of fuses and thermal relay you can use a motor circuit breaker with thermal and magnetic trips, a simple but at least as effective component. The type 3TF8 reversing contactor contains both the forward and reverse contactors and interlocks in one compact housing simplifying the component arrangement.
#FORWARD AND REVERSE MOTOR CONTACTORS FULL#
Motor protection with MCB with thermal and magnetic trips This post is about 3 phase motor forward reverse motor control diagram with mccb, magnetic contactor, push button, thermal overload relay with full wiring.
