YCM7 Se「ies circuit breaker were developed according to the demand of domestic and international market as well as features of like products. Its rated insulation voltage up to 690V is suitable fo 「AC SOHz distribution netwo「k circuit whose 「ated operation voltage is up to 690V with rated operation current up to 300A.lt can distribute powe「 ， protect the circuit and spare the power supply devices from overload, short circuit and under voltage. At the same time, it can P「otect the motor from overload, short circuit and under voltage. This series circuit b「eake「features small volume, high breaking capacity and short arcing. It can be installed vertically (namely vertical installation) and also installed horizontally(namely horizontal installation). It complies with standards of IEC60947 2.
Miniatu「ization The volume of products are miniaturized. For example, 125 is the shell upgraded type of 63, that can satisfy the personal 「equirement fo 「size.
The consistent size They have same shell grade and size but different breaking capacities(C,S,M）出 well as functions(air,leakage of power)
The proper setting of parameter This series can modify long delay time of inverse-time limit when it comes to overloading and paramete「of sho「t ciecuit instantaneous operation. the user can sets the protection features by himself to realize a more p「oper distribution in netwo「K circuit.
Enviroment and Conditions of Installation
Altitude below 2000m
Surrounding medium temperature below +40 degrees above -Sdegree
I、Juelear 「adiation resistance
Max lean degree is 22.5 degree.
Can operate normally when it comes to vibrataion of ship.
Can operate normally when it comes to earthquake(4g).
The medium should be no risk of blasting and can’ t erode the metal and damage insulating gas as well as conductive dust.
Work in the places where there is no rain and snow.
