1. Introduction
JCZ5 12kv vacuum contactor
HVJ6-12 series indoor high-voltage AC vacuum contactor has two types: One is Mechanical holding type, the other is Electromagnetic holding type. It is applicable for three-phase AC 50HZ power system of rated voltage 12KV and below and rated current up to 630 A to open and close circuit remotely and control electrical equipment like high-voltage motor, transformer and capacitive load. It is especially suitable for fields operated frequently. The contactor uses the international fashionable up and down structure arrangement and has the advantages of small, light, easy to maintain and form a complete set of circuit equipment.

For the Mosquito killer Led Bulb Light, is a 900 lumen bulb that doubles as an insect killer. The light features a blue UV LED which attracts insects into a Mosquito Killer grid.And the Mosquito Killer grid uses only 1W of electricity, while the light itself uses a meager 9W – and both can be used independently.They are used at home and outdoor. A brush is provided to clean off insects once the bulb switched-off.Compare to other traditional mosquito killer, this bulb has no chemicals, no sprays and hence no fumes to our life. 2nd generation 2-in-1 LED LIGHT Bulb Plus LED Mosquito Killer Bulb Wattage: 10W Blue UV light Lumen: 900-1000lm Color Temperature (CCT): 6500K Input Voltage: AC 90-130V & 220v-240V With CE and ROHS Operation: Step1: Switch it on,both lighting +killing are on. Step2: Switch on again,light off,only killing on. Step3: Switch on again,killing off,only light on. Step4: Switch off, both off.
