The LIM2010 Line Isolation Monitor (LIM) measures the Total Hazard Current (THC) in an isolated (ungrounded) AC system. The Total Hazard Current is calculated by measuring the system‘s leakage impedance to ground. Alarm indication is displayed on a seven-segment display, LED bar graph, and digital display.

The LIM2010 operates on systems from 100 to 240 V, 50 or 60 Hz. No auxiliary supply voltage is required.

Two separate ground connections are provided for ground connection monitoring. A break in either of these connections will activate the connection alarm.

The LIM2010 features many different alarms, including:

Total Hazard Current (THC)
Transformer overload
Transformer overtemperature
Overvoltage and undervoltage
Ground connection
Insulation resistance and impedance
Ground fault location (when used with BENDER EDS location system)

The LIM2010 is ideal for retrofit applications regardless of the make or type of the existing product. No metal needs to be cut and simple instructions will generally facilitate a change-over in less than one hour.
