Allen-Bradley 1489-M1C050 is supplied by Yueyang Tongtu as part of its industrial automation product range. Yueyang Tongtu has more than 20 years of experience in industrial control automation products and works with imported automation brands including Allen-Bradley. This model is designed for low-voltage three-phase AC motor circuits and supports direct-on-line starting applications where frequent start-stop operation is not required.
1. Motor starting tolerance: The trip curve can tolerate several times the rated motor c阿urrent during normal starting surges, helping reduce unnecessary tripping during motor startup.
2. Dual protection: Thermal protection responds to sustained overload conditions, while magnetic protection provides rapid interruption when a short circuit occurs.
3. Temperature compensation: The overload trip threshold is based on a 40°C environmental temperature reference, helping maintain suitable protection behavior as cabinet temperature changes.
4. Manual isolation: The toggle switch can disconnect the circuit and provide a power isolation point during equipment maintenance or repair.

Allen-Bradley 1489-M1C050 can be applied to compact motor circuits in CNC equipment, including coolant pumps, micro lubrication pumps and chip removal machines.
Small belts and chain-type lifting mechanisms used in material conveying equipment can use this type of motor protection for three-phase AC motor circuits.
Fan coils and air supply or exhaust equipment are suitable applications where compact motor circuit protection is required.
Lightweight centrifugal pumps, dosing pumps and air compressor units can use the device in motor protection circuits for fluid engineering equipment.
Micro mixers and conveyor belts used in packaging and food processing machinery are also suitable for this type of compact motor protection device.
The main difference between this model and an ordinary miniature circuit breaker is the intended circuit application. Motor protection devices use trip characteristics suited to motor starting and operating conditions, while standard miniature circuit breakers are mainly designed for general power distribution circuits.
