插接箱是用戶使用為頻繁，分支電流保護關鍵之部位，箱內裝有自動空氣開關確保分路過載及短路保護，規格分100A、200A、400A、630A，整定電流根據用戶選擇。
      插接箱的插腳是重要部件，本公司*的工藝在插腳上另加二塊65Mn彈簧鋼片，確保插接200次以上仍具有良好的彈性接觸，大于250A的插腳采用可靠的外辦夾緊方法，使其具有良好的接觸。

The tap-off box is a protection device for branch circuits, in which the automatic air switch will shut off electricity when overloading or short circuit occurs. Types include 100A, 400A and 630A, or rated current will be chosen on request by users.
The crucial part in the box is plugs. Our company has developed a technique to add two 65 Mn spring steel slices to the socket to improve contact effect when connection is over 200 times. For a socket loading current larger than 250A, the external clamping will guaranttee the effective contacts.
