FORMULA BLD 電機保護斷路器1SDA127944R1根據(jù)下列結構特性設計制造。
一. 雙重絕緣
FORMULA BLD斷路器的帶電部件（不包括端子）與正常運行過程中操作員操縱的設備的前端部件之間有雙重絕緣。每個電氣附件的底座與電源回路隔離，避免與帶電部件接觸。尤其是操作機構與供電回路隔絕。另外，斷路器的帶電內部零件之間以及接線端子附近有超大的絕緣距離。并且，距離超過IEC標準規(guī)定的距離。
二.熱帶氣候適應性
根據(jù)IEC 60068-2-30標準，采用“variant 1”方法（第7.3.3節(jié)），在55°C溫度條件下對FORMULA BLD系列中的斷路器和附件進行了兩次測試。基于下列原因，F(xiàn)ORMULA BLD系列對于*嚴酷環(huán)境條件的適應性得到進一步保證：
• 絕緣塑殼使用玻璃纖維增強合成樹脂制成；
• 主要金屬部件經(jīng)過防腐處理；
• 鍍層提供Fe/Zn 12鋅鍍層（ISO 2081）保護，不含六價鉻（符合ROHS），達到ISO 4520 2C級耐腐蝕性能。
三.絕緣性能
在分閘位置，斷路器保證符合IEC 60947-2標準要求的絕緣距離，因此能夠避免輸入與輸出端子之間的泄漏電流。
四.操作
操縱桿始終指示斷路器動觸頭的位置，從而保證符合IEC 60073及IEC 60417-2標準的安全、可靠信號（I=合閘，O=分閘，黃色-綠色線=因保護性脫扣而分閘）。斷路器操作機構帶自由脫扣機構，無論操縱桿上的壓力和運行速度如何。保護脫扣自動斷開動觸頭：要使觸頭再次合閘，必須首先將操縱桿從中間位置推到*低端分閘位置，重置操作機構。
