Description
1. Product Title
Bender IRDH275BM-727 – Insulation Monitoring Device (ISOMETER, IT System Protection)
2. Product Overview
The IRDH275BM-727 is a high-performance insulation monitoring device (ISOMETER) developed by Bender for continuous insulation resistance monitoring in unearthed (IT) power systems. It is designed to detect insulation faults early, helping prevent system failures, equipment damage, and unplanned downtime.
The IRDH275BM-727 continuously measures insulation resistance between active conductors and earth, providing real-time diagnostics and alarm signaling when predefined thresholds are exceeded. This capability is critical in mission-critical installations such as hospitals, power plants, and industrial processes where uninterrupted operation is required. The device features LED indication, robust industrial design, and compatibility with insulation fault location systems for enhanced troubleshooting.
