The AIRPAX/Sensata IAL/CEL/LEL series hydraulic magnetic circuit protectors offer a robust solution for power switching, circuit protection, and control in diverse industrial applications. These protectors are designed for use in international markets and are available in a wide range of configurations, including series, series with auxiliary switch, shunt, and relay options. They are suitable for both DC and AC power systems, 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 that all poles open simultaneously in the event of a fault. The availability of auxiliary switches allows for mixing SELV and hazardous voltages, enhancing safety and flexibility in complex systems.
