Product Description

Scope of application

KNHC Modular Contactor (also known as analog contactors and architectural contactors) are mainly used in power systems with AC 50Hz/60Hz, rated working voltage up to 400V and rated working current up to 100A. They are used as remote switches and control circuits in AC-1 and AC-7a (non-inductive or low-inductive loads, resistance furnaces, household appliances and similar low-inductive loads). It can also be used to control the load of household motor. Modular Contactors cant't be used in break short-circuit currents, so appropriate short-circuit protective appliances (such as small circuit breakers) should be selected when using them. It meets the standard IEC 61095. BCH8 contactor can expand auxiliary control, protection and indication functions. BCH8 Modular Contactor is a kind of control device used for long distance connection and disconnection of inductionless or low inductive load, resistance furnace, household appliances and similar low inductive load, household motor, etc. BCH8 Modular Contactor are mainly used in homes, hotels, apartments, office buildings, public buildings, shopping malls, gymnasiums and other places to achieve automatic control functions.

Normal working conditions

Ambient air temperature: The upper limit of ambient air temperature is + 60ºC and the lower limit is - 5ºC. When the AC contactor is installed in the distribution box, spacers must be assembled on both sides to facilitate heat dissipation. Elevation: The altitude of the installation site shall not exceed 2000m.
Atmospheric Conditions: When the installation temperature is + 60ºC, the relative humidity of the air does not exceed 50%. Higher relative humidity can be allowed at lower temperatures, such as + 20ºC up to 90%. Special measures should be taken for occasional condensation due to temperature changes.
Pollution grade: Grade II.
Installation Category: II.
Installation method: TH35-7.5 type guide rail is used for installation. There is no significant impact and vibration at the installation site. It is installed vertically. The inclination between the installation surface and any direction is not more than 5 degrees.

Main technical parameters

Quota system
A) Eight-hour working system: This working system is the basic working system. The agreed free air heating current Ith of the Modular Contactor is determined by this working system.

 Intermittent periodic working system: The operating frequency of the AC contactor is 30 times/h and the load factor is 40%.
Action (operation) condition
In the ambient air temperature range of - 5 +60ºC, when the suction coil of the contactor is applied with a quota to control the power supply voltage Us so as to heat it to a stable state, the contactor should be reliably closed at any voltage in the range of (85%~110%) Us, and released and disconnected between 75% and 20% of the rated control power supply voltage Us.
Product life
Mechanical life: The mechanical life of modular contactor is not less than 1 million times.
Electrical life: The electrical life of analog contactor is not less than 100,000 times.

Company Introduction



Wenzhou Korlen Electric Appliances Co., Ltd, It is a joint venture. My company is a manufacturer including design, development, produce and sale, professional producing MCB, MCCB, RCCB and AC contactor etc. Product enterprises. The company owns import and export power of self-run, expanding Europe and America, Middle East, Southeast Asia etc. Market, set a good Public praise.

The company have more than 1500 workers, including senior engineer among them, engineer at inside of more than 100 technician. And then set up to cover area more than 50 acres, construct area is more than 38000 square meters of the modern industrial zone, providing with the forerunner's standard laboratory and various examination equipments.

Under Korlen people to make great effort unremittingly, designed and developed by oneself, develop and produce the series of MCB, RCCB filled up local blank, attain inter-national advanced level, and acquire more than 20 national patents. The company acquires "30 strong eminent enterprises, top ten of export income, yueqing star class enterprise, attach importance to contract and keeps promise" title of honor for many times past years. Company still the initiative pass ISO 9001 management system verification and 14001 environments management system verification. Our product passed quality verification of domestic and international authority organization like the CB\ SEMKO\ NF\ SIRIM\ SNI\ CE \PCT\ TSE, In the meantime high breaking capacity breaker of our company in this city is the unique product which got " Yueqing famous brand product" by Yueqing people government.
