◉ When wiring, it is necessary to pay attention to the positive and negative poles of the power supply. The power supply needs to enter from the top and come out from the bottom, because of the design characteristics of the power supply inlet;
◉ Easy installation, which can save cables;
◉ It can be used to protect resistive and inductive loads with low inrush current, with a protection efficiency of 5-10In;
◉ Suitable for families, offices, construction, and industrial fields.
◉ Visual red and green indication: Switch status, clear at a glance.
◉ Double thickened handle: At the same time, it can increase the fullness and operation comfort.
◉ PC flame retardant material: PC flame retardant shell, with high temperature resistance, no deformation, beautiful and smooth appearance, not easy to wear, good anti-aging performance.
◉ Top cooling design: Effective heat dissipation, reduce the fault caused by circuit breaker overheating.
