Description:

1.Three phase thermal protector is mainly used in three phase motor which has delta wire connection method, this is a new thermal protector for full thermal protection of three phase motor

2.Working principle: When the motor heats up to the temperature that needs to be protected for some reason, the product can cut off the circuit between the three phases at the 0 potential of the star connection instantaneously, so that the motor stops working, thus playing a protective role

3.Installation: assemble it into the position where is the most easy to heat and not east to rediator the heat, assemble it into the intersection of three groups of different windings, in order to protect the three-phase winding
