ABB ST201M-K1.6 Industrial Safety Relay Module

ABB ST201M-K1.6 is a single-pole miniature circuit breaker in the ST200M family designed to protect industrial equipment circuits from overcurrent and short circuits while fitting into standard protective panel configurations. The variant carries a 1.6 A rating and a K-curve trip characteristic, providing a faster magnetic response to higher fault currents while preserving normal thermal operation for everyday use. It is UL 1077 listed and RoHS compliant, confirming its role as a supplementary protection device for equipment and control circuits in industrial automation; ABB also lists regional variants such as ST201M-K1.6NA for NA markets. Available through major distributors like Mouser and Newark, the ST201M-K1.6 is a compact, 1P MCB that can be integrated into broader protection schemes within the ST200M lineup for reliable, low-current circuit protection in machine and control applications.
