Bender products by category
Bender is a family-owned German manufacturer of electrical safety and monitoring technology, founded in 1946 and based in Grünberg, Germany. The company develops insulation monitoring devices (ISOMETER), residual current monitors, insulation fault locators, neutral grounding resistor monitors, measuring and monitoring relays and communication gateways for IT and earthed power systems. Bender products are known for the yellow DIN rail housings of the ISOMETER and LINETRAXX families.
Insulation, residual current and grid monitoring
The range covers unearthed IT systems for control circuits, main circuits and medium-voltage drives, residual current monitoring for TN and TT systems, fault location with ISOSCAN EDS devices, NGRM monitors for resistance-grounded neutrals and network and system protection relays for generating plants. Bender datasheets name standards such as IEC 61557-8 and IEC 61557-9 for the device families.
Bender for oil and gas, power and process plants
Continuity of supply matters on offshore platforms, refineries, power stations and water plants, where a first earth fault should be reported without tripping. Seven Star LLC supplies Bender monitoring devices to industrial customers in Oman and the GCC, with datasheets and article numbers confirmed before quotation.

Frequently Asked Questions
What does an ISOMETER do?
An ISOMETER is a Bender insulation monitoring device that measures the insulation resistance of an unearthed IT system and alarms when it falls below the set response value, so a first earth fault is reported without a plant trip.
How is an insulation fault located while the plant runs?
A locating current injector, for example in an iso685-D-P ISOMETER, sends a signal into the faulted circuit, and ISOSCAN EDS devices with current transformers show which feeder carries it.
What are residual current monitors used for?
LINETRAXX RCM and RCMS devices monitor residual and leakage currents in earthed TN and TT systems; types with CTUB transformers are AC/DC sensitive.
Which Bender device monitors neutral grounding resistors?
The NGRM700 for high-resistance grounded systems and the NGRM750 for low-resistance grounded systems monitor the resistor, its current and its voltage.
Is Seven Star LLC a distributor of Bender?
No. Seven Star LLC is an independent supplier in Muscat that sources genuine Bender products for industrial customers in Oman and the GCC.
