BK1/GMC-3.5-R

BK1/GMC-3.5-R Application Field and Working Principle

BK1/GMC-3.5-R is a type of current-limiting fuse which is widely used in the overcurrent protection of DC circuits, such as photovoltaic systems, electric vehicle power supplies, large batteries, and high-power motors.

The working principle of BK1/GMC-3.5-R is based on the principle of thermal equilibrium. Its melting element is designed with a certain melt-in temperature and thermal conduction area. When there is an overcurrent in the series circuit where the fuse is connected, the melting element of the fuse melts due to the excessive rise in temperature. When the circuit overcurrent reaches a certain level, the melting element is completely melted, and the fuse is broken, thus protecting the circuit from the damage caused by overcurrent.

The main fields of application for BK1/GMC-3.5-R are the photovoltaic industry, electric vehicle industry, battery and motor fields. In photovoltaic industry, BK1/GMC-3.5-R fuse is used to protect the photovoltaic array in the PV system, overcurrent caused by wiring errors or component damage, and support the reliable operation of photovoltaic system. In electric vehicle industry, BK1/GMC-3.5-R fuse is used to protect the high-power drive system and charging equipment of electric vehicle to ensure the safe operation of the whole vehicle. In battery field, the fuse is used to protect the high-power and high-capacity battery and ensure the reliable operation of the battery. In the motor field, BK1/GMC-3.5-R fuses can protect the motor from overload damage due to its rated current protection.

BK1/GMC-3.5-R is a kind of current limiting fuse with wide application fields. Its application field and working principle have been introduced above. It is a type of fuse that can provide protection for the whole system. Therefore, it plays an important role in ensuring the safety of the system.
