AP Series MIL-PRF-39019 UL, MIL-STD, FM, Sealed Up to 20A AC & DC
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. 延迟机制将检测故障，并且触点将断开。“O”形环衬套密封件和衬套/手柄组件内的硅橡胶密封套提供防水面板的完整性。根据MIL-STD-202 方法 101 测试条件 B 进行盐雾测试，没有腐蚀以及电气或机械损坏迹象。典型应用包括通信、导航和航空仪表、雷达及电源。
获 UL 认可和 CSA 认证的 Airpax™ UP 电路保护器的结构和工作原理与 AP 基本相同。该产品经批准可在 50 伏特 DC 至 20 安培、120 伏特 50/60Hz 至 15 安培和 240 伏特 50/60Hz 至 7.5 安培电流条件下工作。The UP circuit protector is available in single-pole units only, due to UL and CSA creepage specifications and the wide glass terminals utilized. UP 系列提供可选的美国工厂保险联盟 (FM) 认证产品，适用于石化应用。FM approval is available for single-pole, series trip, UP type units only.
Airpax™ AP-MIL 保护器根据 MIL-PRF-39019 和相关规格表生产，遵循严格的生产和测试计划，以保持其合格产品清单 (QPL) 认证资格。已为一、二和三极串联跳闸装置（带或不带辅助触点）提供此认证。请参阅规格表 MIL-PRF-39019/1 至 6 了解关于应用政府指定条款。AIRPAX 保持架代码编号为 81541。
