专家解读视频
This International Standard deals with the safety of electric stationary circulation pumps intended for use in heating systems or in service water systems, having a rated power input not exceeding 300 W, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. The hydraulic and electrical parts of the pump may be in the same enclosure, so that the water flows through the motor and serves as a coolant, or they may be separated.
