The AL-LC-30 is a high power 3-stage lightning and surge protector that provides superior protection for devices such as load cells, weighbridges, resistance temperature detectors (RTD) and strain gage sensors. These types of devices contain sensitive and fragile components that can be easily damaged by lightning and power surges. The AL-LC-30 provides maximum protection to the signal lines, excitation, sense lines and a shield line.

The AL-LC-30 is designed to convert into a failsafe mode in the rare case of a catastrophic surge or lightning event. For this mode, the resistors in the second stage will fuse and portions of the diode array will short. This effectively disconnects the line from sensitive equipment thus limiting damage.

For mounting to masts up to 2 inches in diameter, the HGX-PMT25 mast mounting kit is available (sold separately).
