YCM1 series moulded case circuit breaker(herein after called circuit breaker)is one of our new type circuit breakers, which adopts international advanced design and manufactural technology, it can be divided into L type (standa「d type), M type (highe「breaking type), H-type (cur「ent limiting type) according to the rated ultimate short circuit breaking capacity (lcu). With the features of small and compact, high breaking capacity, short arcing-ove「distance, anti-vib「ation, the circuit breaker is used popularly on land and marine products, they are applied for the power distribution network of AC SOHz,rated insulation voltage 800V (YCM1 63 to SOOV), rated working voltage 690V(YCM1-63 to 400V) and below, rated current up to 1600A, it can be used to distribute elect「ic power and protect power equipment against overload, short circuit, undervoltage etc, It also takes p「otective effect when motors infrequently sta「t and protecting against overload, short circuit and lacking voltage. In the se「ies, frame ranging from 63-630A three-pole product also comes with a transparent cover, it is convenient for customer to observe the product ope「ation. The circuit breaker can be installed vertically, or horizontally.  This p「oduct complies with standard of IEC60947 2, GB14048.2, specification of 6A only has electromagnetic (instantaneous) type; with () is not recommended 225L type withcage te「minal can be elevated.



  1. Blank for power distribution,2 fo「motor protection

  2. Blank for di「ect operation with handle, Z for operation with rotary handle, P for motor driven operation.

  3. There are 4 types of N-pole for 4P breaker: A:Without current release components, N Pole is always at making status(not breake「s); B:Without current release components, N-Pole makes with the other three poles; C:With cu「rent release components, N Pole makes with the other three poles; D:With current release components, N-Pole is always at making status(not b「eake「s)

Functin and features

  1. Temperature: 5。C~+40°C; the average value within 24h shall not exceed +35。C. For the circuit breaker with thermo magnetic release, +40℃is set to be the standard temperature for ratings. For temperature not between -5。C~+40℃,please contact us for temperature compensation correction;

  2. Altitude: not exceed 2000m (Please contact with us for reduction coefficient if altitude at the mounted site exceed 2000m)

  3. Pollution grade: Grade 3;

  4. Ai「conditions: At mounting site, relative humidity not exceed 50% at the max temperature of +40℃, highe「「elative humidity is allowable under lower temperature. For example, RH could be 90% at +20℃,special measu「es should be taken to occurrence of dews.
