CrocSee AC Current Switch is designed for AC current monitoring, motor overload protection, automatic control system and other applications. This device senses a current draw of between 1amp and 50 amps and closes a set of contacts while AC current is passing through sensor. <br> <br> <b>Main Specifications: </b><br> Enclosure Dimensions(LxWxH): 88 x 25 x 50mm; Or approx. 3.46 x 0.98 x 1.97 inch <br> Sensor Hole Diameter: 20mm (0.79 inch) <br> Mounting Holes: 2x5mm holes spaced 76mm on base (2 x 0.19”holes spaced 3”on base)<br>Voltage Range: 120-240VAC<br>Switch Rating: 2.5 A @ 120 VAC/240VAC (Only works with AC current, not for DC current)<br>Contact Type：Normally Open<br>Operating Temperature: -20 to 45℃（-4 to 113℉）<br>Humidity Limits: 0-95% RH, non-condensing<br>Response Time: ≤200ms<br> Accuracy: 1%<br>Hysteresis: ≤1%<br> <br> <b>NOTE: </b><br> 1. Disconnect and lock-out all power sources prior to installation.<br>2. The current switch has a rating of 2.5 Amps maximum. If the secondary device (which is conncted with the switch) draws more than 2.5 Amps, then you will need a separate high current relay.<br> 3. A load must be applied across the NO switch to work. If no load is applied across the NO switch, these NO terminals will not close with correct operating primary current. <br> 4. The switching current is NOT calibratable. However, it is sensitive enough to detect any current draw of between 1amp and 50 amps. <br> <br> <b>Package includes: </b><br>1x AC Current Switch<br> 1x Instruction Manual <br><br><b>Warranty:</b><br><b>1-year free replacement or full refund without return.</b><br>If the item you have received is defective in any way, please message us for free replacement or refund without return.
