190 MPCBs
Allen-Bradley 190 Motor Circuit Protectors (MPCBs)
Allen-Bradley 190 series motor circuit protectors (MPCBs) are used to protect motors and branch circuits in industrial automation systems. They provide compact motor circuit protection with manual disconnect capability and are commonly installed in MCCs and control cabinets where dependable protection and serviceability are important.
The 190 series is frequently used with motor starters and contactors to help protect motor circuits in applications such as conveyors, pumps, fans, compressors, and general industrial machinery. When replacing an MPCB, matching the correct adjustable current range to the motor full-load amps (FLA) is one of the most important factors. You should also verify the number of poles, rated voltage, and any required protective ratings or accessory compatibility based on your existing control panel design.
Typical applications
- Motor protection for conveyors, pumps, fans, and compressors
- Industrial control panels and MCC installations
- OEM machinery and packaged equipment
- Retrofits and maintenance replacement for installed systems
- Spare inventory planning for critical production assets
Key selection factors
- Adjustable current setting range (match motor FLA)
- Number of poles and voltage class
- Short-circuit protection and breaking capacity requirements
- Mounting style and panel layout compatibility
- Accessory support (aux contacts, signaling, etc.)
