The Allen Bradley 1489-D1C100 is a miniature circuit breaker specifically designed for DC power systems. Functioning with a rated current of 10.0 A, it is suitable for a variety of electrical applications that require compact protection solutions. This circuit breaker operates under a maximum voltage rating of 125 VDC in accordance with UL standards and can handle up to 250 VDC per IEC specifications.

This model contains one pole and is characterized by a thermal-magnetic protection mechanism. Its interrupting rating of 10 kA at 480Y/277V AC ensures that it can protect electrical circuits from overcurrents effectively. The breaker features a Type C trip curve, which tripped under specific fault conditions, making it reliable for diverse electrical configurations.

Installation is facilitated through DIN rail mounting on standard 35mm rails, which enhances ease of use in various settings. With an IP20 rating, the 1489-D1C100 provides limited protection against solid objects, emphasizing the need for careful placement in environments where exposure to dust or conductive elements is minimal.
