YCM6 Series MCCB

YCM6, YCM6RT series circuit breaker is a new generation of breaker.

This breaker is applied for the distribution network of AC 50/60Hz, rated insulation voltage 800V, rated working current up to 800A, which is for electric energy distribution, circuit protection, protecting power supply facility from being destroyed by the fault of overloading, short circuit and undervoltage. And it is also used for protecting, overloading, short circuit and undervoltage of the motor.

This breaker has such characteristics as high short circuit interrupting capacity, shortarcing and etc., which is a ideal product for users. This breaker can be installed vertically or hori-zontally.

Standard:lEC60947-2

Product Details

Features

1. Design miniaturized

The miniaturization of product volume can meet the individual needs of customers on installation size.

2. Size uniformed

Completely consistent installation size with same shell level beyond different breaking capacity(S,M) and different functions(air,leakage).

3. Reasonable parameter setting

Circuit breaker 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°C to +40°C (+45°C for shipping product)

3. Humidity resistance

4. Bacteria resistance

5. Nuelear radiation resistance

6. Max lean degree is 22.5 degree.

7. Can operate normally when it comes to vibrataion of ship.

8. Can operate normally when it comes to earthquake(4g).

9. The medium should be no risk of blasting and can't erode the metal and damage insulating gas as well as conductive dust.

10.Work in the places where is no rain and snow.

Overview

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 room temperature 40°C.

Test current	Current time	Conventional time		Inta status
Test current	Current time	In≤63	In<63	Inta status
Conventional non-trip current	1.05	1h	2h	Cold status
Conventional trip current	1.30	<1h	<2h	Hot status

2. When ambient temperature is +40'c for electrmotor protection breaker, power on for every pole, inverse time limit characteristic of no temperature compensation is in the following sheet.

Test current	Current time	Conventional time	Initial status
Test current	Current time	In≤800	Initial status
Conventional non-trip current	1.0	2h	Cold status
Conventional trip current	1.2	<2h	Hot status

3. Action property of the short-circuit release of the breaker

♦ Instant trip (for power distribution)l=10ln

♦ Instant trip (for motor protection)l=12ln

♦ Current setting accuracy ±20%

Internal accessories

Internal accessories of YCM6,YCM6RT series include undervoltage release, shunt release and auxiliary alarm release, their main technical parameters and wiring diagram are as follows:

	Undervoltage release
	Rated voltage of power supply	Main features
	AC220,AC240 AC380,AC415	A.Undervoltage release should act when voltage drops to within 70%and 35%of the rated voltage. B.The undervoltage release should not be closed to prevent the circuit breaker from closing when the voltage is lower than 35%of the rated voltage. C.The undervoltage release should be closed to ensure reliable closing of the circuit breaker when the voltage is equal to or greater than 85%of the rated voltage.
	Shunt release
	Rated voltage of power supply	Main features
	AC24,DC110 AC220,AC380	Shunt release can work reliably when the rated voltage value is at 70%and 110%.
	Auxiliary alarm contact
	Rated voltage of power supply	Main features
	Auxiliary switch AC 125V 5A,AC 250V 3A DC 125V0.4A,DC 125V0.2A	Shunt release can work reliably when the rated voltage value is at 70%and 110%.
	Alarm switch AC 1255A,AC 250V 3A DC 125V0.4A,DC 125V 0.2A	Provide differentiated signals for the circuit breaker at "normal work"and "fault free trip" positions.
	Auxiliary alarm switch AC 125V 5A,AC 250V 3A DC 125V0.4A.DC125V0.2A	Provide differentiated signals for the circuit breaker at "close","open"and "fault free trip" positions.
