Product Overview
The Allen-Bradley 1489-M3C160 is a Bulletin 1489-M thermal-magnetic miniature circuit breaker manufactured by Rockwell Automation. It provides branch circuit protection in compatible industrial electrical installations and is specified with a three-pole configuration, 16A rated current and C-curve tripping characteristic.
The C characteristic includes a manufacturer-specified magnetic tripping band of 5–10 times rated current, subject to applicable standard test conditions and operating temperature.
The breaker carries a maximum 480Y/277V AC UL/CSA system voltage rating and a separate 400V AC IEC/EN rated operational voltage. These ratings apply under different standards and must not be treated as interchangeable for all electrical distribution configurations.
Rockwell Automation specifies a 10kA interrupting capacity under UL 489 and a 15kA IEC/EN ultimate short-circuit breaking capacity for the applicable 1489-M range. The operating installation must be checked for prospective short-circuit current, voltage system, applicable certification and all required installation conditions.
The Bulletin 1489-M design includes 35mm DIN rail mounting, dual terminals and a compact modular construction. The manufacturer specifies an IP20 protection rating, with an operating ambient temperature range of −25°C to +55°C. Installation and wiring must follow the current manufacturer documentation and local electrical codes.
Rockwell Automation currently lists catalog number 1489-M3C160 as Active.
Actual seller photographs show an Allen-Bradley carton marked 1489-M3C160, Series D, with 16A, 3 Pole, C Characteristic and Product of Bulgaria. The carton barcode matches the manufacturer's published UPC 885630618579.
A rear-view photograph of the circuit breaker has also been provided, but the physical unit's printed catalog information is not sufficiently legible for independent exact-model confirmation. Electrical functionality and manufacturer authenticity have not been independently tested or authenticated. Please confirm the actual unit, electrical system rating and installation requirements before ordering.
