Elektrische Sicherheit für ungeerdete Stromversorgungen
Ground-fault detectors for ungrounded systems

Bender's advanced ground-fault detection and insulation monitoring devices (IMD) along with fault-location solutions (EDS series) for AC and DC systems detect ground faults before leakage current may even be present. The iso685 ISOMETER series includes advanced network-communication capabilities.

Protection panels

Bender's certified protection panels (GFGC, LifeGuard®, MarinaGuard®) are a complete solution for ground fault detection and interruption.

Isolated power systems for healthcare facilities

Hospital isolation panels for patient treatment in healthcare facilities for compliance with standards such as NFPA 99 and CSA Z32. Features a LIM2010 Line Isolation Monitor and dedicated power isolation transformer, as well as options for ground-fault location.

Elektrische Sicherheit für geerdete Stromversorgungen
Ground-fault relays for solid and resistance-grounded systems

Bender's RCM, RCMA, and RCMS series relays monitor leakage current in AC (single and three phase) and DC power and control circuits. Available in single-channel and multi-channel options. LifeGuard® and MarinaGuard® integrated panels are ground-fault interrupters (GFI) for a wide variety of applications.

HRG and LRG systems

Neutral grounding resistors (NGR) monitoring with a state-of-the-art NGRM700 or NGRM750 integrated in a wide range of solutions (HRG series).
