JM1-100/1P

Short Description:

JM1-100/1P series mould case circuit breaker is new developed and manufactured by adopting international advanced technology.It is a supplied with rated insulation voltage 800V and used for circuit of AC 50HZ,rated operating voltage AC 400V or below rated operation current up to 800A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current,short circuit and under voltage,the products is capable of preventing damage of circuits and supplying units.The product confirms to IEC60947-2 standard.

Note:

1.The MCCB has L; M; H types according to their rated limit short-circuit breaking capacity.

2.The MCCB is advantageous for its compact body, high breaking capacity(some even on flying arc), short arc-casting.

3.The MCCB has function of insulation wit its mark

4.The product complies with IEC60947-2, GB14048.2. Type code & signification
5.N-P type from 4-P has 3 types: A type: N-P without current tripper(normally open);
6.B type: N-P without current tripper working together with other 3P;
7.C type: N-P without current tripper working together with other 3P;

8.No code for distribution type breakers, 2 for motor-protection type;

9.No-code for distribution type breakers, 2 for motor-protection type;

It can be divided into L (common) type, M (standard) type and H (high) type. L type with connecting current equal to relevant frame level and M type with breaking capacity equaling to their frame level according to their rated limited short short-circuit breaking capacity (l c u).

10.Normal working situation

11.Altitude 2000m and below;

12.Ambient temperature no higher than+40ºC(45ºC for watercraft)no less than-5ºC;

13.Stand moist air;

14.Stand salty&oil mildew;

15.Most gradient 22.5°;

16.Atmosphere without corrupt&electric air and no danger of explosion;

17.Without rain effect.
