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.

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.

Curve

Operating conditions

1.Temperature: -5℃~+40℃; the average value within 24h shall not exceed +35℃. For the circuit breaker with thermo-magnetic

release, +40℃ is set to be the standard temperature for ratings. For temperature not between -5℃~+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.Air conditions:

At mounting site, relative humidity not exceed 50% at the max temperature of +40℃, higher relative humidity is allowable under

lower temperature. For example, RH could be 90% at +20℃. Special measures should be taken when dew occurs.
