AIRPAX/Sensata's IAL/CEL/LEL series hydraulic magnetic circuit protectors are designed to provide low-cost power switching, reliable circuit protection, and accurate circuit control for equipment in the international marketplace. These protectors are available in a wide variety of configurations, including series, series with auxiliary switch, shunt, and relay options, with choices of delays and ratings in DC and/or 50/60Hz or 400Hz versions. They are UL listed, CSA certified, and CCC approved, making them suitable for a broad range of industrial applications. The multi-pole units feature internally coupled trip mechanisms, ensuring simultaneous opening of all poles in case of a fault, which is crucial for polyphase circuits and systems requiring coordinated protection.
