Product Overview
The Otowa LD-C22EFS Power Surge Protective Device (SPD) is a high-performance transient voltage surge suppressor manufactured in Japan by Otowa Electric Development Co., Ltd. Engineered for power distribution systems and industrial control panels, it provides robust protection for sensitive electrical equipment against damaging power surges, lightning-induced transients, and voltage spikes.
Operating on 250V systems with a low voltage protection level ($U_p$) of 1.3kV, the LD-C22EFS rapidly diverts excess current away from downstream electronics. Its compact design allows for easy integration into control cabinets, power panels, and industrial machinery requiring Japanese industrial-grade reliability.
