Normal operating conditions and installation conditions
1, the ambient temperature: -25 °C ~ +65 °C.
2, the working frequency: 45 ~ 60Hz.
3, working voltage: 24V ~ 380V.
4, the output interface load capacity: AC380V 1A, COSΦ = 0.3 ~ 0.4.
5, installation size: in line with JR16 thermal relay standards.
6, installation location: any angle of installation and protection class IP40.
The protector adopts the core-type current sampling detection technology, thyristor output, simple structure, convenient use, reliable operation, and has the advantages of no power consumption, long life, no arc generation during operation, etc. It is the ideal replacement for thermal relay in China. Motor protection products
The main cause of overload is the improper selection of the conductor cross-section, and the actual load has exceeded the safety current of the conductor.
Too many high-power devices are connected to the line, which exceeds the load capacity of the distribution line.
Lighting lines in important material warehouses, residences, and public buildings may have power lines that may cause long-term overloading of wires or cables, and when insulated conductors with a burn-proof jacket are used for laying on flammable or hard-to-burn building components. , should take overload protection. Line overload protection should adopt automatic switch. During operation, the setting current of the automatic switching long-delay operation should not exceed the long-term allowable load current of the line. If a fuse is used for overload protection, the rated current of the fuse melt shall not be greater than the long-term load current of the line. When the automatic switch is used as the protection device, its current release should be installed on the phase line in the neutral three-phase four-wire system; in the neutral three-phase four-wire system, It is allowed to be installed on two phases; ungrounded two-phase two-wire system allows installation on one phase.
In a communication power system, the function of automatically disconnecting the power supply due to a large load is called overload protection.
