CNC 3 Pole MCCB Molded Case Circuit Breakers YCM7

3 Pole

General:

YCM7 series circuit breaker is a new generation of breakers. This breaker is applied for the distribution network of AC 50Hz, rated insulation voltage 800V, rated working current up to 800A, which is for electric energy distribution, circuit protection, protecting power supply facilities from being destroyed by the fault of overloading, short circuit, and Undervoltage. It is also used to protect, overload, short-circuit, and undervoltage the motor. This breaker has characteristics such as high short circuit interrupting capacity, short arcing, etc., which make it an ideal product for users. This breaker can be installed vertically or horizontally. Standard: IEC60947-2.

Features

1. Designing the miniaturization of product volume can meet the individual needs of customers on installation size.
2. Size uniformed, completely consistent installation size with the same shell level beyond different breaking capacities (S, M) and different functions (air, leakage).
3. Reasonable parameter setting Circuit breakers can realize long-time delay overload inverse time, short circuit instantaneous action protection functions such as parameter setting, users can set their own protective properties required, the distribution network is used in the circuit breaker on the lower level with more reasonable.

Operating conditions

1. Altitude less than 2000m
2. Ambient medium temperature is from -5℃ to +40℃ (+45℃ for shipping product)
3. Humidity resistance
4. Bacteria resistance
5. Nuclear radiation resistance
6. The max lean degree is 22.5 degrees.
7. It can operate normally when it comes to the vibration of the ship.
8. It can operate normally when it comes to earthquakes (4g).
9. The medium should have no risk of blasting and can't erode the metal and damage insulating gas, as well as conductive dust.
10. Work in places where there is no rain or snow.

Thermo-magnetic release

1.      The circuit breaker (for power distribution) has reverse time breaking characteristics of overcurrent release in all pole states and is energized simultaneously at a room temperature of 40℃.

2.      When the ambient temperature is ±40℃ for the electromotor protection breaker, power on for every pole, inverse time limit characteristic of no temperature compensation is in the following sheet.

3. The action property of the short-circuit release of the breaker

◆ Instant trip (for power distribution) I=10In

◆ Instant trip (for motor protection) I=12In

◆ Current setting accuracy ±20%
