Sinetamer LA-ST180 Parallel 380V / 480V Transient Voltage Surge Supressor

The SineTamer© LA series of units blends outstanding high-energy “impulse” suppression with excellent “ringwave” transient protection. This durable device is intended for general purpose and sensitive/critical load applications. The LA-ST180 is typically installed at service entrances up to 1800 amps, distribution and sub distribution panels. Compact size and non-metallic enclosure design also allow it to be installed directly inside electrical panels and individual equipment disconnects. The internal installation provides the absolute shortest possible lead length and optimum performance. This economical device has features that are not available in devices costing many times its price. Its compact size makes installation a breeze. Maintenance Free operation and 20 Year Unlimited Free Replacement Warranty provide peace of mind. Standard unit is Type 2 10kA UL Nominal Discharge Current; Optional Type 2 20kA IN is available.
