What is 033707.5PXS

033707.5PXS is a low voltage fuses with pole-mounted interruption technology. It is widely used in low and medium voltage distribution systems. It has advantages of good breaking capacity, high accuracy of setting current, safety and reliable operation, low power consumption and long service life.

Application Field

033707.5PXS fuse is suitable for use in low and medium voltage systems for isolating, protection and circuit disconnection of power generation, power transmission, and supply systems.

It can be used to protect transformers, capacitors, motors, power cables, rectifiers and other power equipment. It also can be used as disconnecting switch in low voltage distribution lines, with an operating voltage of AC 400/415 volts and rated short-term overloading current of up to 5A.

Working Principle

033707.5PXS fuses have an internal over-pressure sensing system. When the current exceeds the rated current value, the over-pressure sensing system will be activated, which triggers an alarm mechanism and an interruption mechanism. The alarm mechanism sends an alarm signal to the control room of the distribution system, while the interruption mechanism causes immediate disconnection of power supply thus protecting the equipment from damage.

Once the current is below the rated current value, the system will automatically reset. The 033707.5PXS fuse can be used in two ways: manual reset and remote reset. In manual reset, the user needs to physically reset the fuse, while in remote reset, the reset is done remotely. It is important to note that 033707.5PXS fuse has a built-in uv detection system that protects the device from exposure to ultraviolet radiation.

Conclusion

033707.5PXS is an important component of the power distribution system. It is designed to provide protection for the equipment, interrupt the power supply when the current exceeds the predetermined value, and reset in order to restore power supply. The 033707.5PXS fuse has advantages of good breaking capacity, high accuracy of setting current, safety and reliable operation, low power consumption, long service life, and built-in uv detection system.
