The 1489-M1C200-QTY1 miniature circuit breaker, produced by Allen Bradley, is part of the Bulletin 1489 series. Its build is ideally suited for single-pole applications, supporting a rated current of 20 A. With a weight of just 0.29 lbs, it offers a compact design that is suitable for various installations. This circuit breaker is equipped to handle AC voltages up to 277V and DC voltages accordingly rated at 48V. This versatility makes it applicable in a range of electrical systems.
Operating within a frequency range of 50 Hz to 60 Hz, the 1489-M1C200-QTY1 utilizes a C-Curve trip characteristic. This trip curve allows it to manage temporary overloads efficiently, making it ideal for circuits with intermittent loads. Its interrupting rating is marked at 10 kA, ensuring that it can handle overcurrent situations without failure, thus providing essential protection. The breaker can be easily mounted on a DIN rail, making it user-friendly for panel installations.
When it comes to environmental protection, the IP ratings are significant. The circuit breaker boasts an IP40 protection rating for its front and internal parts, offering resistance against solid objects larger than 1 mm. The terminals are rated at IP20, providing satisfactory protection against large solid objects but are not dust-tight. Overall, the 1489-M1C200-QTY1 miniature circuit breaker is an efficient solution for individual circuit protection in various commercial and industrial applications.
