Showroom Product Company Profile

Fuse is a temperature sensitive/ thermally responding device that serves as an intentional weak link in an electrical circuit.
It interrupts overload and short-circuit conditions when its metallic element melts; thereby halting the overcurrent condition.
Purpose of the fuse is to prevent FIRE!

Basic Theory
1. Circuit Protection - Current (ampere)
2. Complete flame proof construction
3. Completed & Perfect protection. Short circuit protection & overloading
4. The fusible resistor is applied to safety circuit in a wide range of electronic sets. F (quick-acting) & T (time-lad)
5. Low temperature coefficient, high precision, low noise and good high frequency performance
6. There are 5 color bands on surface. The 5th band is in WHITE color means fusible metal film resistor

Breaking/ Interrupting capacity
Interrupting rating also know as Breaking Capacity or Short Circuit Rating, the interrupting rating is the maximum approved current which the fuse can SAFELY interrupt at rated voltage.
IEC STD Fuse type: High Breaking Capacity/ Enhance Breaking Capacity/ Low Breaking Capacity.

Chian Chia Electronics (C. C. O) was established in 1986 by chairman Mr. Chen Chu Zhi; In 1996, the second factory in Shen Zhen "Chian Chia Electronics (Shenzhen) Co., Ltd. " Was built. The total number of employees reached 450 people and the main products are different kinds of resistors and relative machines...

In order to satisfy changing international markets and developing demands in the world, in 2012, C. C. O set up another company, "Shenzhen Boyuxing Electronic Co., Ltd. " Due to the long term experience in research and technology development, we have invented a variety of resistance equipments such as, cutting machines, welding machines, forming machines, glass fiber winding machines and other special resistance equipment. We are constantly developing new products and production lines have been built from our own brand; Moreover we enjoy a high position in this highly competitive electronics market.

The C. C. O chairman Mr. Chen thinks "a business should be regarded as a strive group in human performance. " Hence, C. C. O is more considerate towards the environment, and everything we can to support the advancement of society and bring benefit to its people.

Nowadays, especially with the importance of energy and environmental protection, C. C. O wants to make a contribution for our next generations and the earth's well being. Through the key concept of environmental protection, we set up a company, "Chian Chia Sea Mild Co., Ltd. " With Japanese technology, we developed various types of environmentally friendly living supplies, like green shower gel, green detergent, environmentally friendly hand-wash, environmental protection washing powder and a greater number of environmental protection products. We are planning to implement promotion and franchise stores in China in 2010.
