ST2L364 4P ( RCCB )Residual Current Operated Circuit Breaker (Electromagnetic)
Application
The product is used in AC50 / 60HZ two poles 230V, four poles 400V,rated current up to 63A, It can automatically and immediately cut off power supply once someone suffers from electric shock or leakage current above specified value. It can effectively protect personal security and avoid the damage to equipment. The residual current operated circuit breaker can also function as overload and short-circuit protection and unfrequent changeover of line under normal condition. The product is suitable for industry, business, building, residence, etc. It is conformity with GB16916.1, IEC61008-1 standards.
