WSB9-125 series miniature circuit breaker has advantage of fine and small in size, light in weight, reliable performance, big breaking capacity, fast release, rail installation, with high flame retardant and impact resistance plastic for frame and parts, and long service life. It mainly applies in lines of AC 50Hz or 60Hz, single pole 230V, 400V for double, three and four poles for overload and short circuit protection, meanwhile in lighting lines and infrequent on-off electrical equipments under normal circumstance.
The product meets standards of GB14048.2, IEC60947-2,at international level.
WSB9LE-125 series earth leakage circuit breaker applies in lines of AC 50Hz, rated voltage single pole double lines, double poles 230V, three poles, three poles four lines, four poles 400V, rated current from 63A to 125A. The residual operation current action circuit breaker can cut fault power quickly in a very short period to protect personal and device safe when getting an electric shock or leakage current of the grid exceeds the regulated value, to protect the overload or short circuit of line and electric motor at meanwhile, to make frequent switch of the line and infrequent starting of the electric motor.
The product meets standareds GB14048.2 and IEC60947-2.
