Lus ceeb toom:

1. Yog hais tias qhov kev ncua deb ntawm theem yog 150 hli, nws yog ib qhov tsim nyog yuav tsum tau nce lub insulated partition ntawm theem;

2. The width of fixed contact is 40mm when the distance between phases is ≤180mm; the width of fixed contact is 60mm when the distance between phases is >180mm;

3. Qhov hloov hauv av muab cov khoom tso tawm hauv ob qho kev qhia; lub ntsiab ncej txuas mus rau sab laug rau sab laug ua haujlwm, thiab txuas mus rau sab xis rau txoj haujlwm txoj cai.
