QL-1-13-DM-KM-05 is a single-pole miniature AC circuit breaker from the QL-Series, featuring hydraulic-magnetic technology for precision tripping independent of ambient temperature. This ultra-compact 13mm width module offers a 5A current rating with a medium time delay (KM curve) and an instantaneous trip point of 6-12 times rated current. The dual mount (DM) configuration provides flexibility with a 57mm escutcheon and black body, supporting both DIN and dual rail mounting options. Approved to UL 489, CSA, IEC/EN 60947-2, VDE, CE, and CCC standards, it delivers interrupting capacities of 10kA at 120VAC and 5kA at 240VAC for single-pole applications. Ideal for UPS equipment, power conditioning, alternative energy systems, and AC branch circuit installations where reliable overcurrent protection is required.
