SBW三相熱保護器
SBW系列保護器，動觸片上設置有兩個觸點，同時對應在底座上設置有兩個靜觸點，當被保護電器溫度增高時所產生的熱量傳遞到雙金屬元件上，達到預定動作溫度設定值時，雙金屬元件便迅速動作，推動動觸片斷開觸點切斷兩個迴路；當溫度下降到額定復位溫度值時，雙金屬元件自動恢復接通電路。 SBW系列熱保護器主要Y型三相電機、控制並聯電路電器。
Used in three-phase motors, transformers and various three-phase motor products
SBW series protector, two contacts are arranged on the movable contact piece, and two static contacts are arranged on the base correspondingly, and the heat generated when the temperature of the protected appliance is increased is transmitted to the bimetal element to reach a predetermined operating temperature. When the set value is reached, the bimetal element acts quickly
