DESCRIPTION

APL111-1-66-203 is a three-pole magnetic circuit breaker designed for reliable, low-cost power switching, circuit protection, and circuit control in industrial and commercial applications. The breaker features a molded phenolic case with a trip-free mechanism that forcibly returns the handle to the OFF position upon overload, ensuring positive circuit isolation. With a nominal amperage rating of 20.0 amperes and 50/60 Hz delay characteristics (code 66), this unit incorporates stainless steel springs and plated parts for enhanced durability and corrosion resistance. The breaker is UL and CSA recognized as a component-appliance control and operates with coil impedance of 0.0050 ohms at rated current for 50/60 Hz delays. Common applications include motor control, power distribution systems, and equipment protection where reliable overload sensing and manual circuit control are required.
