Allen-Bradley 1489-M1C010 1-Pole 1A C-Curve Circuit Breaker

Allen-Bradley 1489-M1C010 Miniature Circuit Breaker

Product Overview

The Allen-Bradley 1489-M1C010 is a Bulletin 1489-M thermal-magnetic miniature circuit breaker manufactured by Rockwell Automation. It is designed for branch circuit protection in compatible industrial electrical installations and features a single-pole configuration, 1A rated current and C-curve tripping characteristic. The Type C magnetic tripping band is specified as 5–10 times the rated current under applicable test conditions. Rockwell Automation confirms a maximum 277V AC UL/CSA rating and 48V DC UL/CSA rating for this single-pole model, with a separate 230V AC IEC/EN rated operational voltage. Unlike multi-pole Bulletin 1489-M variants, the single-pole model must not be assigned the 480Y/277V AC voltage rating. Manufacturer specifications include 10kA UL 489 interrupting capacity, 15kA IEC/EN ultimate short-circuit breaking capacity (Icu) and 11.25kA IEC/EN service short-circuit breaking capacity (Ics). The ratings are determined under different standards and must be applied according to the relevant system requirements. This compact 17.5mm-wide circuit breaker provides 35mm DIN rail mounting, dual terminal construction and IP20 protection. Its specified operating ambient temperature range is −25°C to +55°C, subject to the manufacturer's application and derating requirements. Rockwell Automation currently identifies catalog number 1489-M1C010 as an Active product. Actual seller photographs show an Allen-Bradley carton labeled 1489-M1C010, Series D and a device rear nameplate carrying the same exact model and series. The packaging identifies the 1 Pole, 1 A, C Characteristic configuration and Product of Bulgaria origin. The barcode corresponds to manufacturer UPC 885630619613. The carton is marked QTY 2. This is a packaging marking only; the buyer must confirm the actual order unit and quantity being supplied. The photographs support model identification but do not constitute independent authentication or electrical function testing. Confirm circuit voltage, available fault current, installation conditions and purchasing quantity before ordering.
