MCB MCCB OEM AC/DC miniature Moulded Case circuit breaker Mini Circuit Breakers
• Application Scope
ERM1E series moulded case circuit breaker(hereinafter referred to
as the circuit breaker),is suitable for occasional conversion and
motor protection under the circuit of AC 50Hz,60Hz,rated insulation
voltage of 800V,rated operational voltage of 400V and rated
operational current to 800A.Circuit breaker has functions of
overload long time delay inverse time,short time delay inverse time
of short circuit,short time delay definite time of short
circuit,short circuit instant,under-voltage protection,residual
current protection(optional) and open phase protection function
(optional),and can also prevent the line and power equipment from
being damaged.The circuit breaker has complete and precise
protection features,can improve power supply reliability and avoid
unnecessary power outages.The ‘Z.B’ type control has communication
interface,and can be ‘four control’ to mee the requirement of
control center and automation systems. The leakage circuit breaker
ca be classified into two types of M(moderate high breaking) and
H(high breaking) according to the rated limit short circuit
breaking capacity(Icu).Is has features of small volume,high
breaking,short flashover and vibration resistance,etc. It can be
installed vertically (vertical assembly) or horizontally
(horizontal assembly). The reverse incoming line of circuit breaker
shall not fall into the line is not acceptable,i.e.,it’s only
allowed to connect power line of 1,3,5 and 2,4,6 of load line.
• Normal Working Environment
- Altitude<=2000m
- Ambient temp:-5℃~+40℃
- Able to tolerate the influence of moist air
- Able to tolerate the influence of salt mist and oil mist
- The installation category of main circuit for circuit breaker is
III,and II for the rest of the auxiliary circuit and control
circuit.
- When the highest temperature of +40℃,relative humidity of air is
not more than 50%,and under low humidity can be allowed to have
higher relative humidity.Special measures should be taken on
condensation occasionally produced due to temperature change.
- Maximum gradient is 22.5℃
- In the medium without explosion danger and the medium has not
enough corrosion to metal,to destroy the insulation gas and
conductive dust.
- In the place without invasion of rain and snow.
