IALHK11-33211-4 is a hydraulic magnetic circuit protector from the IAL/CEL/LEL Series, designed for low-cost power switching, reliable circuit protection, and accurate circuit control. This two-pole unit features internally coupled trip mechanisms and can be configured with either a single toggle handle or a handle per pole. The device offers multiple delay curve options including DC delays (51, 52, 53, 59), AC 50/60Hz delays (61, 62, 63, 69), and AC 400Hz delays (41, 42, 43, 49), with operating characteristics that ensure no trip at 100% rated current. Available with various voltage ratings up to 480V AC and 300V DC, the circuit protector supports current ratings from 0.20A to 400A depending on configuration. Common applications include equipment requiring international marketplace compliance where inherent circuit protection attributes are desired without specific standards certification requirements.
