BK1/GMA-3-R

Fuses protect electrical circuits from damaging when a short circuit or an overload occurs. The BK1/GMA-3-R is a kind of fused-switch which can effectively protect electrical circuits from all kinds of faults against fire and shock when overload happens, and disconnect the circuit when overload combusts.

In electrical connections, fuses protect electrical circuits from abnormal conditions. Excessive current or overvoltage caused by a short circuit or overloaded equipment can be damaging the circuit. BK1/GMA-3-R fuse-switch can prevent electrical devices from being damaged due to these abnormal conditions. With its practical, compact design and optimal operating parameters, it ensures high current-carrying capacity and a reliable safety response time.

The BK1/GMA-3-R fuse-switch has a wide application field, capable of providing efficient protection for all types of appliances, motors, and other electrical devices. It is suitable for both single and three-phase systems, designed to fit different types of standard switchgears. Moreover, it is ideal for electrical installations with extreme temperature and humidity conditions.

The working principle of BK1/GMA-3-R fuse-switch is that it has two parts: the fusion chamber and the trigger switch. When the current reaches its maximum rated current, the fuse wire in the chamber gets heated and melts. As a result, the contact between the switch and the power supply is separated and the circuit can no longer be supplied with electricity. The trigger switch, which is connected to the power supply, measures the amount of current passing through the circuit and triggers the trip when it detects an excess. The BK1/GMA-3-R fuse-switch is equipped with a thermal overload re-trip system, which will automatically reset the switch after the excess current is gone in order to trip the circuit again when there is another overload.

The BK1/GMA-3-R fuse-switch is designed to achieve high current-carrying capacity yet remain reliable and safe. It has a maximum rated current of up to 63A and a rated voltage of 400V. Moreover, it is enclosed in a dustproof, tamper-proof IP54 enclosure for durability and safety.

Overall, the BK1/GMA-3-R fuse-switch is an efficient way to protect electrical systems from potential overloads and short circuits. With its wide application field, high current-carrying ability, and reliable working principle, it is a safe and effective solution for protecting equipment from damage.
