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 UL 508A certified protection panels (GFGC, LifeGuard®) are a complete solution for protecting personnel and equipment.

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.

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® integrated panels are ground-fault interrupters (GFI) for a wide variety of applications.

High-resistance grounded (HRG) systems - Neutral grounding resistors (NGR) monitoring with a state-of-the-art NGRM700 or NGRM500 integrated in a wide range of solutions (HRG series).

Protective relays - Monitor a multitude of key system values, including voltage, current, phase sequence, ground continuity, and more. Check out our protective relays here.
