Equipment characteristics:

The equipment chamber is welded with high-quality steel, the plate is coated and sealed, and the surface is anti-static, anti-rust, and anti-corrosion coated. The upper part of the equipment is equipped with a panel, a power switch, and a variety of wire ends (for delay tripping test). The equipment is reasonably designed and used with the advantages of convenience, simple operation, reliable performance and beautiful appearance.

According to the delayed tripping of standard IEC60898-1 clause 9.10.2.1 or 9.10.2.2, the three chambers in SN2501-3C can be tested independently at the same time. According to the instantaneous test of IEC60898-1 clause 9.10.3.2-9.10.3.4, it can only be tested in chamber 1.

Test type	Chamber 1	Chamber 2	Chamber 3
Delay tripping test	√	√	√
Instantaneous tripping test	√

Chamber 1, Chamber 2, and Chamber 3 are independent and can be freely combined for testing.

Note: The delay and instant of box 1 cannot be tested at the same time.

Chamber 1 instantaneous trip test and 28-day test cannot be performed at the same time.

Temperature rise and 28-day test procedure compatibility

Test type	Chamber 1	Chamber 2	Chamber 3
Temperature rise	√	√	√
28-day test procedure	√	√	√

The temperature rise test and the 28-day test are compatible with each other to and can be performed simultaneously within each chamber and also can be performed independently in different chambers.

Testing can be carried out both simultaneously and at different times relative to other cameras chambers.

In different chambers can be carried out simultaneously and independently different types of tests from those provided.

Each chamber is equipped with a heating device, with a temperature control range of RT+5~50°C, so that the model samples in the chamber can be used at normal ambient temperatures, and includes a three-way ambient temperature monitoring function.

The software must allow the execution of any test program to be terminated at any time without having to wait for the standard procedure to complete, retaining the results obtained at the time of termination.

Test principle:

This test equipment adopts the principle of low voltage and high current output, uses the large current in the machine to isolate the output current of the transformer, sets the current size through the touch screen, and the constant current source adjusts the size of the output current of the transformer, which has the function of automatically stabilizing the current. Set the test time through the touch screen display and compare the test trip time to judge the quality of the circuit breaker.
