As the exclusive representative of AIRPAX in Israel through Amironic, we are proud to present the AP/UP series of magnetic circuit protectors. This product line, developed in compliance with MIL-PRF-39019 standards, offers state-of-the-art protection solutions for demanding applications across military, aerospace, communication, and industrial domains. Here is an in-depth exploration of these circuit protectors—their features, configurations, and key applications.

Introduction to the AP/UP Series

The AP/UP series by AIRPAX combines precise circuit protection with power switching capabilities. Unlike thermal circuit protectors, which can exhibit variations in trip current under different ambient temperatures, these hydraulic magnetic circuit protectors maintain consistent performance across a wide temperature range (-40°C to +100°C). The series features a trip-free mechanism that ensures overload protection even if the handle is forcibly held in the ON position.

The AP/UP circuit protectors are available in DC, 50/60 Hz, and 400 Hz configurations, with multiple delay curves to suit specific application requirements. In addition, the UP series is UL recognized and CSA certified, making it suitable for safety-critical environments.

Key Features

  • Sealed Construction: The AP series is fully sealed, offering waterproof panel integrity with an “O”-ring bushing seal and silicon rubber gland. This ensures durability in harsh environments, including those subjected to salt spray as per MIL-STD-202.
  • Trip-Free Action: Prevents the circuit from remaining closed during overload conditions, enhancing safety and reliability.
  • Wide Operating Range: Available in a range of configurations, supporting up to 20 amperes at 50 VDC, 15 amperes at 120 VAC, and 7.5 amperes at 240 VAC.
  • Robust Design: Withstands 100G shock and 10G vibration without tripping, ensuring resilience in extreme conditions.
  • Endurance: Exceeds 10,000 operating cycles, demonstrating exceptional longevity.

MIL-PRF-39019 Compliance

The AP-MIL series, part of the AP/UP product line, is manufactured to meet the rigorous standards of MIL-PRF-39019. This military specification ensures the protectors meet stringent performance, reliability, and environmental criteria. The AP-MIL protectors are subjected to extensive testing for vibration, shock resistance, and environmental sealing, making them highly reliable for mission-critical applications. The compliance with MIL-PRF-39019 highlights AIRPAX’s commitment to delivering products suitable for military and aerospace use.

At Amironic, we provide full support for sourcing M39019 part numbers, ensuring seamless integration with your military-grade systems. Our expertise allows us to guide customers in selecting the precise configuration required for their applications.

Configurations and Options

The AP/UP series supports multiple configurations to meet diverse application needs:

  1. Series Trip: Combines overload protection with power disconnect functionality.
  2. Shunt Trip: Controls two separate loads by tripping both simultaneously when one load exceeds the threshold.
  3. Relay Trip: Allows sensing in an electrically isolated circuit, suitable for interlock or emergency shutdown systems.
  4. Voltage Trip: Facilitates rapid power disconnection via low-power inputs, ideal for sensitive circuits.
  5. Auxiliary Switch Options: Provides remote indication for power-on and power-off conditions, supporting alarms and monitoring systems.

The protectors are available in single-, two-, and three-pole configurations, with custom combinations to address specific circuit requirements.

Military-Grade AP-MIL Protectors

For defense and aerospace applications, the AP-MIL series adheres to MIL-PRF-39019 standards, maintaining Qualified Products Listing (QPL) compliance. These units are subjected to stringent production and testing protocols to ensure consistent quality and performance.

The AP-MIL protectors are offered with:

  • One, two, or three poles.
  • Auxiliary contacts for remote monitoring.
  • Compatibility with MIL-PRF-39019/1 through MIL-PRF-39019/6 specifications.

Technical Specifications

  • Current Ratings: 50 mA to 20 A.
  • Voltage Ratings: Up to 50 VDC, 120 VAC, and 240 VAC.
  • Short Circuit Capacity: 1000 A at 32 VDC and 240 VAC for supplementary protectors.
  • Inrush Pulse Tolerance: High pulse delay options for improved tolerance to inrush currents.
  • Dielectric Strength: Withstands 1250 V RMS at 60 Hz between terminals.
  • Insulation Resistance: Exceeds 100 MΩ at 100 VDC.

Applications

The AP/UP series finds widespread application in:

  • Communication systems.
  • Navigation and aircraft instrumentation.
  • Radar systems.
  • Power supplies.
  • Petrochemical environments (FM-approved UP models).

Ordering and Customization

The AP/UP series offers extensive customization options, including variations in delay curves, current ratings, and auxiliary configurations. Each unit is coded for precise identification, ensuring compatibility with specific application requirements.
