2P 800 Volt DC MCCB for Moulded Case Circuit Breaker Mini Circuit Breakers
• Application Scope
ERM1L series moulded case leakage circuit breaker ( hereinafter
referred to as the leakage 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 400Vand rated operational current to 630A(800A).The
leakage circuit breaker has protection function to avoid overload
,short circuit and under-voltage,for assuring the prevention from
damage of circuits and power-supply devices.Meanwhile,can provide
indirect contact protection to people,and prevention from fire
danger caused by long-standing ground fault which can not be
detected by over current protection.When other protective devices
are failure,ERM1L leakage circuit breaker with rated residual
current action for 30mA can provide additional protection of direct
contact to people. The leakage circuit breaker can be classified
into two types of M moderate high breaking )and H (high breaking
,except 4 poles )according to the rated limit short circuit
breaking capacity ( Icu).It has features of small volume ,high
breaking ,short flashover and vibration resistance ,etc .. It can
be installed vertically ( vertical assembly )or horizontally
(horizontal assembly). It conforms to requirements of standards
GB14048.2,IEC60947-2 and Appendix B of moulded case leakage circuit
breaker . 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.
• Notes :
1.According to the rated limit short circuit breaking capacity it
can be classified into two types of M (moderate high breaking )and
H (high breaking). 2.Operate by handles directly without code: P
means electric operation;Z refers to turning the handle.
3.Distribution circuit breaker without code :2 means to protect the
electric motor . 4.It can be classified into three pole and four
pole according to the number of poles for products .The neutral
form (N pole )of 4 poles product is classified into two types :
-Over -current release will not be installed on N pole ,and the N
pole is switched on all the time ,without to be on -off with other
three poles together . -Over -current release will not be installed
on N pole ,and the N pole is switched on /off with other three
poles together .( N pole is switched on and then off ). 5.No alarm
unit module is without code ,and alarm unit module should be
indicated when ordering.
• 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 - 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.
