Retrofit

Retrofitting with Bender

Many older facilities exist in various industries with either decommissioned ground fault monitoring equipment or unreliable ground fault solutions that are outdated. This can result in unexpected equipment damage, constantly spending resources looking for faults, and potential harm to personnel. The products below are some of the commonly used replacements for older or obsolete products. After 75 years of producing ground-fault and insulation monitoring products, many changes and advancements have occurred. The below products often have additional features that may enhance system protection, increase sensitivity, log data, and add communications. Newer Bender devices often feature universal power supplies in a broader variety of supply voltage. The products are designed with compact form factors that make them backward compatible and save installation space.

If you cannot find a Bender product that you are currently looking to replace, please contact us.

Bender NGRM500 replaces RC48N
  • Meets or exceeds global standards
  • Full Frequency protection for non linear loads
  • Continuous metering for system health and predictive maintenance
  • Network communications for remote access

NGRM500 has a compact form factor to allow retrofit of older NGR monitors such as the Bender RC48N or the SE-325. While these products are still available on the market they do not meet AS/NZS2081 or the newest Canadian Electrical Code requirements for impedance grounded systems. The NGRM500 features open and short neutral-to-ground path detection, AC/DC ground-fault detection, communications, three output contacts with separate resistor fault and ground-fault operation and an HMI for easy configuration and display of information.

Bender CMGF420 replaces Schneider GC200
  • Easy to read display for monitoring ground fault current
  • Compact form factor to suit numerous applications
  • Ground-fault protection at every level: main, feeder and branch circuits

Obsolete ground-fault products or older products used on applications requiring non-sensitive pickup levels can use CMGF420 ground-fault relays with 600:1 or 1000:1 current transformer to provide protection settings from 100 -1200 A.

Bender RFB700 replaces Federal Pioneer DSA and DSP MKII
  • Full frequency protection for non-linear loads
  • Constant metering for system health and predictive maintenance
  • Network communications for remote access
  • Current transformer connection monitoring

The RFB-700 is an ideal replacement for older Federal Pioneer devices. It was designed to be installed in the same footprint but add enhanced digital protection and communications. NGR monitoring, phase indication and feeder level ground-fault indication allow users to quickly locate ground-faults in a power distribution system. Upgrading to Bender ground-fault current sensors further enhances the protection offered and data available to the user.

Bender iso685 replaces IRDH and older ISOMETER® series
  • Easily programmable via front display
  • Easily replace multiple models with one unit and customized configurations
  • EDS automatic fault location compatibility

Many of the IRDH or older iso series of products can be replaced with one of the varieties of the iso685 relay. This relay also replaces older “3-Light” ground fault detection systems. For specific assistance for products not listed on this page please contact our application support team.

Bender CTUB100 Series replaces W..AB CT’s
  • Broad spectrum AC/DC current sensing
  • Improved accuracy for finer detail monitoring
  • Uses standard 24 volt power supply

Current transformer series have been evolving as quickly as customer loads have advanced. To enhance protection and provide wider frequency response on applications many customers have replaced their W series CT’s with CTUB-102 CT’s and an appropriate RCM or RCMS ground-fault relay. Note the W..AB Series are obsolete and are being replaced with the CTUB100 series.

Simplify inventory
Products such as the iso685 can replace multiple specialty products with application-specific configurations.

Enhanced ground fault protection
Newer devices can provide better protection for variable frequency applications and CT monitoring.

Communications - IOT
Many newer Bender devices include communications as a standard – allowing products to meet customer Internet of Things needs.

Enhance system reliability
Replace equipment before end of life to prevent unscheduled downtime.
