About Bender
Bender GmbH & Co. KG, headquartered in Grünberg (Hesse), develops and manufactures solutions that make electrical systems smarter and safer. The product portfolio includes insulation monitoring devices (ISOMETER®) for unearthed IT systems, residual current monitoring devices (LINETRAXX® RCMS/RCMA) for TN and TT systems, ground-fault resistance monitoring devices (NGR), power quality and energy meters (PEM, MID-certified energy meters), measuring and monitoring relays, current transformers, insulation fault location systems (ISOSCAN®), test equipment for electrical equipment (UNIMET®) as well as transfer and monitoring systems for medical locations (MEDICS®, ATICS®, isolating transformers). In addition, condition monitoring systems (COMTRAXX® CP907-I, POWERSCOUT®, edge500) are offered for predictive maintenance. The products are used, among other things, in mechanical and plant engineering, hospital technology, data centers, mining, railways, e-mobility, and the oil, gas and petrochemical industries. The family-owned company, founded in 1946, employs around 1,350 people and delivers worldwide.

Products and Technologies
Insulation monitoring
Continuous monitoring of the insulation resistance of unearthed IT networks up to AC 1000 V/DC 1500 V, e.g. for medical IT systems, photovoltaics and drive/inverter applications.
Residual current monitoring (LINETRAXX®)
AC, pulsating and all-current sensitive monitoring of earthed TN and TT systems for fault and residual currents, also available as the SmartDetect series.
Ground-fault resistance monitoring
Monitoring of neutral grounding resistors in high-resistance and low-resistance earthed systems for limiting the fault current.
Power quality and energy measurement
Universal measuring devices and MID-certified energy meters for capturing currents, voltages, power, energy consumption and harmonics.
Insulation fault location (ISOSCAN®)
Systems and portable locator devices for pinpointing insulation faults in IT systems.
Test equipment
Safety testers for testing electrical equipment and medical-technical devices, including calibration.
Power supply for medical locations
Transfer and monitoring systems as well as isolating transformers for the power supply of medical rooms.
Condition monitoring
Condition monitor with gateway (CP907-I), POWERSCOUT® and edge500 for condition-based maintenance and predictive maintenance.
Current transformers
All-current sensitive measuring current transformers (type B) for residual current and load current measurement.
