Sinetamer RM-ST40 Parallel 380V – 480V Transient Voltage Surge Supressor

The SineTamer RM series of units blends outstanding high-energy “impulse” suppression with excellent “ring-wave” transient protection. This durable device is intended for general purpose and sensitive/critical load applications. The RM-ST40 is typically installed at small service entrances up to 400 amps, distribution and subdistribution 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 RM-ST40 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 15 Year Unlimited Free Replacement Warranty provides peace of mind.
