AC Moulded Case Circuit Breaker,
Moulded Case Circuit Breaker 3P,
415V MCCB 4 Pole 63 Amp
AC440Vac Moulded Case Circuit Breaker 3P MCCB EM63B/EM63N 4 Poles 415V
♦ EM series moulded case circuit breaker is applied with with rated insulating voltage 500V, rated working voltage 690V in AC (50/60) Hz condition and used for infrequent exchange. The MCCB is protecting in overload, short-circuit, and under voltage situation to protect circuit system and power device from damage.
♦ The MCCB can be devided into B,N,S,H types according to their rated limited short-circuit breaking capacity.
♦ The MCCB is advantageous for its compact body, high breaking capacity, short arccasting and superior aseismatic function.
♦ The MCCB has function of insulation with its mark""
♦ The product complies with IEC 60947-2, GB14048.2
Normal installtion conditions:
♦ Height above sea level: ≤2000m
♦ Ambient medium temperature: ≤+40℃, ≥5℃
♦ It can endure the effect of humid air and the effect of salt mist, oil mist and fog bacteria.
♦ In the place within the midium without danger of explosion and without corrosion of metal box, damage of insulation gases
and conductive dust
♦ No damage of rain and snow
♦ Pollution degree: 3
