CCM1 Molded Case Circuit Breaker General
YCM1 series moulded case circuit breaker(herein after called circuit breaker) adopts
international advanced design and manufactural technology, it can be divided
into L-type (standard type), M-type (higher type)according to the rated ultimate
short circuit breaking capacity (Icu). With the features of small and compact, high
breaking capacity, short arcing-over distance, anti-vibration, the circuit breaker is
used popularly on land and marine products, which are applied for the power
distribution network of AC 50Hz,rated insulation voltage 800V (YCM1-63 to 500V),
rated working voltage 690V(YCM1-63 to 400V) and below, rated current up to
1600A. It can be used to distribute electric power and protect power equipment
against overload, short circuit, undervoltage etc, It also takes protective effect when
motors infrequently start and protects against overload, short circuit and lacking
voltage. In the series, frame ranging from 63-630A three-pole product also comes
with a transparent cover, it is convenient for customers to observe the product
operation.
The circuit breaker can be installed vertically, or horizontally.
Standard : IEC60947-2.
1.Blank for power distribution,2 for motor protection
2.Blank for direct operation with handle, Z for operation with rotary handle, P for
motor-driven operation.
3.There are 2 types of N-pole for 4P breaker:
A:Without current release components, N-Pole is always at making status(not
breakers);
B:Without current release components, N-Pole is made with the other three poles.
