UEM5 series MOLDED CASE CIRCUIT BREAKER
■UEM5 series direct current molded case circuit breaker (hereinafter referred to as MCCB) are suitable for use in DC circuits with rated DC voltage of 1500V or below and rated current of 100A ... 500A. The MCCB has overload and short circuit protection function preventing that equipment and circuits experience the electrical damage. The MCCB is widely applied in the direct current distribution systems of photovoltaic power generation, electric power, rail transit and electric locomotive, direct-current power supply, etc.
●Product features
■The electric arc will be rapidly extinguished due to advanced “magnetic blow-out” technology and special contact design.
■Thanks to advanced "air-blowing" technology and special material used for arc extinguishing chamber, the electric arc will be conducted into the chamber rapidly.
■The direct current is reliably interrupted and higher electrical endurance ensured due to special arc extinguishing system and cross arrayed arc extinguishing grid.
■Effective use of the arc extinguishing chamber space enlarges the gap between the contacts, which can length en the arc much faster thus turning it off.
■This MCCB can be equipped with shunt release, auxiliary contact, alarm contact, motorized operating and manual operating mechanism.
■The design of cassette-type accessories ensures fast and reliable accessory installation.
■The positive and negative electrodes of the incoming line terminal are reversible, making the wiring convenient.
■Different wiring method (down in and down out/up in and down out) makes the wiring flexible.
