The 203-22-1-65-153-7-2-6 is a Type 203 supplementary protector designed for circuit protection with inverse time delay characteristics and magnetic supplemental protection. This device features a 50/60 Hz long delay configuration (-65 designation) with a delay time of 1.50 seconds, providing reliable overcurrent protection across a wide range of current ratings from 0.02 to 30 amperes. The protector includes a rocker handle construction with non-illuminated design and operates with standard U.S.A./CSA construction specifications. It is commonly used in industrial and commercial electrical systems where precise time-delayed protection is required to prevent nuisance trips while maintaining effective fault protection.
