AIRPAX/Sensata LELHK11 series hydraulic magnetic circuit protectors offer a cost-effective solution for power switching, circuit protection, and control in a wide range of equipment. These protectors are designed for the international marketplace and are available in various configurations, including series, series with auxiliary switch, shunt, and relay options. They are suitable for applications requiring reliable protection and control in both DC and AC environments, and are often used in polyphase circuits, single-phase three-wire systems, or in two or more electrically isolated circuits. The multi-pole units feature internally coupled trip mechanisms, ensuring simultaneous opening of all poles in the event of a fault.
