Top 10 Best Current Switch

N.O. Universal Outputs 2.5A 120 VAC240VAC In 240V circuit, only one 120V hot line is connected.. Self-powered, no external power supply required. Accurate Dependable Offers a sensing range of 1 to 50 amps and universal, solid-state outputs Accuracy 1. Faster Response Time Once current flow is detected, it closes a set of contacts immidiately Response Time 200ms. NOTE If you want to test the operation of the sensor switch, a load must be applied across the NO contacts otherwise, it will not work..

Turns 120 VAC devices on when input current is sensed. UL 94-V0 rated for flammability safety. Item Package Dimension 4.0 L x 4.0 W x 4.0 H. Item Package Weight 1.0 lb.

Self-powered, no external power supply required.Action current 0.2-30A AC, adjustable with a potentiometer.. LED indicator can conveniently and intuitively indicate the working status of the switch.Hysteresis is less than 1 and can be used under strong magnetic conditions.. The switch has no limit on the number of opening and closing, and the reaction speed reaches the ms level.The outer casing is made of self-extinguishing material ABS.. High-power MOS tube contactless electronic switch.Straight-through structure design, isolation withstand voltage up to 2000V.. Suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch of automatic control system and so on..

Unique Current Sensing Technology. If the tool motor connected to the 'A' port exceeds 30W, the vacuum connected to the 'B' port will automatically delay 1s to turn on, which helps prevent circuit overloaded by large current if tool and vacuum power-on at the same time. Make the Work More Effective. Automatic delays 1s to turn on the vacuum when you start your tool, and delays 7s to turn off the vacuum to clean the inlet tube when you complete your work. Saving time and electricity, reducing airborne toxin and work area noise that can lead many health problems. Suitable for Most Medium Duty Workloads. Etoolcity automatic vacuum switch has a starting threshold of approximately 0.25 amps30watts at 120V and 60watts at 220V, perfectly suited for medium-sized work loads such as most Miter Saws, Table Saws, Power Sanders and Routers, and extend the life of your vacuum. More Safety. Adopting high-cost, UL-certified American Standard 14AWG power cord which allowable passage with a large current that more than 30A, the Etoolcity Automatic Vacuum Switch can work stably within 3600W. The switch's shell has PCABS V0 grade flame retardant material, it is more reliable and safe to protect work. Two Installation Methods. You can use screws to fix the power module part, or use strong nano-markless hook sticker to attach directly to the wall. Both ways are very strong.
