NSP SPD

Eaton’s SPD series surge arresters provide the most advanced surge protection for industrial and commercial applications. Available in NEMA 1, NEMA 4 or NEMA 4X stainless steel housings, there are solutions for all electrical applications, including service entrances, distribution switchboards, control panels and point-of-use equipment.
The NSP series of surge arresters is a new line of optimized devices from Eaton, which includes protection classes B and C (i.e. I and II) respectively. It protects your expensive and sensitive electrical and electronic equipment, such as mainframes, IT and digital system equipment and precision electronics, against voltage spikes. lightning or surge caused by the opening and closing of large switches in the circuit.
All NSP series products are among the most cost-effective products available, and the multipole products are equipped with standard busbars, making installation quick and easy, while avoiding use long cable connections with excessive residual voltage.
