VITZRO EM Air Circuit Breaker is a circuit breaker that passed new IEC standard(IEC60947-2, LV switch equipment and control equipmentcircuit breaker)and KS standard(KSC 4620)development tests. 

It is a premium circuit breaker that is convenient to use with a design that enables a short breaking time and maximum safety and protection functions.

It features a dramatically improved draw-out rail guide for easier draw-out. 

It is equipped with intelligent protection and highly accurate and selective protection features with reliable power supply. 

 It provides improved reliability with a highly accurate current sensing circuit, which is used in measuring devices.

It is optimized for the package panel system due to its compact size. 

The smaller exterior enables 3-stage loading of low-voltage panel.

The insulation molding of the front side and mechanism of the machine provide improved worker safety. 

 The precise structure and superior breaking capability of the machine provide higher reliability. 

 It offers excellent switching performance and durability.

The LED display of the intelligent trip device allows users to easily identify the trip status. 

It satisfies the needs for an intelligent control center and automated system with remote measuring and control based on the intelligent trip device. 

The digitalized surge protector(dialog setting) allows for improved reliability and convenience. 

It ensures easy and precise monitoring and identification of currents from low to maximum currents(4000A). The shunt coil overheat protection feature provides improved reliability and convenience.
