The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail. 2. Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage. 3. With phase loss protection, when the protected line is in the running state or non-operating state, any phase will have a phase failure fault and delay 2S action. 4. Withreverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action. 5. Voltage unbalance protection means that a three-phase voltage imbalance will affect a safe protection of the line. When the three-phase unbalance ratex100%>10%, the protection delay 2S action. 6. Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC. 7. Undervoltage protection means that the voltage of the protected line is lower than the set value, and the delay is 3-8S, and the recovery is 3-20VAC. 8.Products are widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, etc Specification: Condition: 100% The Main Circuit: Rated Voltage: 690VAC Connecting Wires of the Main Circuit: The insulating copper wire has a carrying area of 1.0 to 2.5 mm. If a single strand of copper wire can be directly inserted into the terminal; if a cord is used, a needle type terminal must be added to the wire to ensure reliable connection. Auxiliary Circuit: A normally open and a normally closed contact that is electrically inseparable. Use Category: AC15, DC13 Contact Capacity: 250VAC 2.5A, 30VDC 1.5A Conventional Heating Current: 5A Voltage Protection Range: 2000 - Over voltage protection +15%, Under voltage protection -15% Size: Approx. 68 x 30 x 76mm / 2.7 x 1.2 x 3in
