Protetor bimetálico pequeno de sobrecarga do motor
Usually, 5AP/2MP/6AP is used as the motor overload protection device. When in use, connect the thermal element (three-phase or two-phase) of the overload protector in series to the main circuit of the motor. Connect the main contact of the thermal relay to the contactor coil circuit in series.
The necessity of motor overload protection:
When the motor is running, it is generally allowed to overload for a short time (the output power exceeding the rated value is called overload). No entanto, if the overload time is too long and the temperature rise of the motor exceeds the allowable value, it will cause insulation aging, shorten the service life, and even burn the windings in severe cases. Portanto, in order to prevent damage to the motor due to long-term overload operation, the overload time must be limited. This protection is overload protection.

When the motor overload operation, the current is increased, the heating element temperature rises, the bimetal gently curved, and thus exceeds the predetermined value, and finally open the normally closed contacts, so that the motor coil is deenergized. So as to cut off the power of the motor and avoid the motor from being burnt due to long-term overload operation.

O que é um interruptor térmico?
O interruptor térmico é baseado no ambiente de trabalho das mudanças de temperatura, deformação física ocorre dentro do produto, um elemento de controle que é automaticamente ligado ou desligado, também conhecido como interruptor de controle de temperatura, proteção térmica, controlador de temperatura e assim por diante. Os métodos de controle de temperatura comumente usados são:
TERMÓSTATO DE AÇÃO DE fluência, PROTETOR DE MOTOR
VA1/VAA1 substitui o protetor térmico bimetálico do termostato de ação de fluência PEPI com maior sensibilidade à corrente:
[O TERMOSTATO DE AÇÃO PEPI CREEP] VAA1 adota controle bimetálico, e o interior é um circuito de baixa resistência com contatos banhados a ouro. Design de controle de temperatura constante e tamanho pequeno. É adequado para cobertores elétricos, almofadas de aquecimento elétrico e todos os tipos de pequenos eletrodomésticos que requerem função de temperatura constante.

The function of automatic cut-off switch to prevent overheating
The automatic cut-off device against overheating is an electronic technology protection device. It can automatically cut off the power supply when electrical equipment overheats to avoid damage and danger caused by overheating of electrical equipment. In modern electrical equipment, automatic cut-off devices to prevent overheating have become an indispensable safety measure.
