product details

products description

Low voltage fuse type isolating switch is a combination of fuse, isolator, and switch, which disconnects the circuit by melting the melt when the current exceeds the specified value.

Structure:

It mainly includes an installation base, static contacts, dynamic contacts, fuse links, and blades. The static and dynamic contacts are respectively installed on the insulation column.

Working principle:

When the current exceeds the specified value, the fuse generates heat to melt the melt, thereby disconnecting the circuit and protecting equipment and personal safety.

Characteristics:

Good selectivity, strong overcurrent protection characteristics, and high breaking ability.

Small size, comprehensive functions, and beautiful appearance.

Strong resistance to moisture and heat, safe and reliable operation.

Application:

Widely used in low-voltage distribution systems, control systems, and electrical equipment, especially in power plants, substations, and industrial power consumption.

Low voltage fuse type isolating switches play an important role in power systems with their unique advantages, ensuring the safe operation of circuits.

Is mainly used for distribution circuits and motor circuits with rated voltage AC 380V-690V (45-62Hz). The switch can withstand short-circuit current up to 800A and is widely used in power systems as power switches, disconnectors and emergency switches to ensure circuit safety and reliability.

The HR17 series switches can also be used for circuit protection to prevent fault conditions such as overload and short circuit. Despite its powerful functions, it is generally not recommended to directly turn on and off individual motors to ensure the safe operation of the equipment. This product complies with relevant standards and is suitable for a variety of industrial and commercial applications.
