Description

The Siemens LIM-1 loop isolator module provides short circuit protection on MXL intelligent device circuits (ALD). When a short is detected by the LIM-1, it isolates the affected segment of the circuit, allowing the remaining devices to continue operation. The Siemens LIM-1 is self-restoring, automatically reconnecting to circuit segment when the fault is remove.

The Siemens LIM-1 also includes a yellow LED which illuminates to indicate that the device has been activate. The LIM-1 mounts in either a 411/ 16″ square, 3½” deep or 2 gang electrical box and are supply with a cover plate with an opening for the LED.

It can be wire in either a Style 4 or Style 6 configuration. The LIM-1 does not occupy a device address on the ALD circuit and requires no programming. Up to twelve LIM-1s may be install on each ALD circuit. The isolator, model LIM-1 shall be a self-restoring device requiring no programming, and shall not occupy an address on the intelligent device circuit. It shall be capable of being configured in either Style 4 or Style 6 wiring.
