Sinetamer LA-ST120 Parallel 220V/480V Transient Voltage Surge Supressor
The SineTamer© LA series of units blends outstanding high-energy “impulse” suppression with unsurpassed “ringwave” transient protection Frequency Attenuation Network®. This durable device is intended for general purpose and sensitive/critical load applications. 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. The LA-ST120 is extremely effective in limiting internally generated transients and is an absolute must on panels feeding office locations and/or microprocessor based equipment. 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.
Parallel connected, transient voltage surge suppressor device utilizing both high-energy handling and Frequency Attenuation Network® circuitry for virtual elimination of ring wave type transients
