AP Series MIL-PRF-39019 UL, MIL-STD, FM, Sealed Up to 20A AC & DC
The Airpax? AP series magnetic circuit protector is available in either DC, 50/60Hz or 400Hz versions and with various delays to match the protector to specific application requirements. Unlike a thermal circuit protector, the AP does not change its trip current over a wide temperature span.?One of the most important features of this protector is the “trip free” action, meaning the circuit will not remain closed in the presence of an overload, even though the handle is held in the ON position. 延遲機制將檢測故障，并且觸點將斷開。“O”形環襯套密封件和襯套/手柄組件內的硅橡膠密封套提供防水面板的完整性。根據MIL-STD-202 方法 101 測試條件 B 進行鹽霧測試，沒有腐蝕以及電氣或機械損壞跡象。典型應用包括通信、導航和航空儀表、雷達及電源。
