CB-PRO
AMR PEMCO vs. Traditional Molded Case CB’s
Increased Safety
- Reliability of vacuum contactor – No arcing across contacts
- Password Protected
- Operating parameters set by foreman
- Alerts personnel of hazardous conditions
- Proven to withstand harsh environmental conditions
- Low voltage and easily configurable (4 button keypad, 4×20 LCD) control unit
- Electrical lockout for repair and maintenance – Employee shortcuts avoided
- Customized setting and parameters – Magnetic and thermal fault settings, etc.
- Ground fault detection – prevents electric shock from “hot” frame of equipment
- Monitoring of “stuck pole (bottle)” reduces chance of injury
Cost and Time Savings
- Reduction in maintenance downtime – remote electrical lockout capability
- Eliminates molded case circuit breaker replacement – Rated for 1 million trips useful life
- Increased trip accuracy leads to decreased troubleshoot time
- Eliminates nuisance tripping
- Prevents equipment damage – Phase loss and under-voltage monitoring
- Reduction in spare parts inventory
Remote Capabilities
- Compatible with Modbus and other PLC digital I/O
- Labor savings in pinpointing problems and resuming production
- Data Logging
- Start amperage and voltage requirements
- Fault history date and time stamp
- Record of hours closed
- Provides accountability for downtime
- Over-current conditions
- Predictable maintenance vs. unscheduled downtime
- Spare channels for customer specifications
