220/380, 240/415, 277/480 VAC, 3-Phase Wye (5-Wire)
The SineTamer© LA series of units blends outstanding high-energy “impulse” suppression with unsurpassed “ring-wave” transient protection Frequency Attenuation Network®. This durable device is intended for general purpose and sensitive/critical load applications. The LA-ST300 is typically installed at service entrances up to 3000 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. The LA-ST300 is extremely effective in limiting internally generated transients and is an absolute must on panels feeding office locations and/or microprocessor based equipment.
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.
