小型バイメタルモーター過負荷保護装置

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). しかし, 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. したがって, 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.

いつもの, 5モーター過負荷保護装置としてAP/2MP/6APを使用. 使用時, 感熱素子を接続します (三相または二相) モーターの主回路に直列の過負荷保護装置. サーマルリレーのメイン接点をコンタクタコイル回路に直列に接続します.

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.

[モデル]: 5AP/2MP/6AP/ 3MP+PTC/2AM/
[Temperature Range] : 50℃-180℃
[特徴]: 小さいサイズ, suitable for the installation requirements of micro-motor overload protection; Provide the most reliable safety protection when the motor is locked; The combination of bimetallic sheet and heating wire has fast tripping.
