Product Description

McMurdo BreaktHRU EPIRB Hydrostatic Release Unit - McMurdo Hydrostatic Release BreaktHRU kit for EPIRBs (Replaces 82-400A) - 82-962-001A The McMurdo HRU (Hydrostatic Release Unit) is the water pressure activated automatic release mechanism for the Smartfind Plus EPIRB Auto Housing ( E5 / G5 ) and older McMurdo EPIRB models (E3 / G4, Rescue406 / Precision406 ). The HRU is designed to automatically release the Auto Housing cover and discharge the Smartfind Plus EPIRB at a depth of between 2 - 4 metres. This action is carried out by a small charge within the HRU forcing a blade to cut through a plastic retaining bolt, releasing both the Auto Housing cover and a spring that forces a lever arm to eject the Smartfind Plus EPIRB. McMurdo Hydrostatic Release Data Sheet (.pdf) The HRU is a sealed unit which is battery operated and requires replacement every 2 years. The HRU Replacement Kit contains all of the necessary parts to both replace the HRU and the retaining bolt.
