Underwriters Laboratories (UL) 508A is an American and Canadian standard for industrial control panels. Circuit breakers and fuses receive considerable attention as they are the first line of defense when things go wrong. This engineering brief explores the difference between the UL listed circuit breaker and the supplementary protector. Representative examples are shown in Figure 1 including: Left: Phoenix Contact TMC 81A 01A which is a UL 489 listed circuit breaker Right: Phoenix Contac…
