3 Phase Circuit Protection Voltage Monitoring Relay Phase Failure Sequence Protector

About this item

• Features: 1. The protector base adopts 35mm rail type or device type, and has two screw hole structures inside, which can be directly installed separately or HT35 rail. 2. Indicated by three indicators: normal, phase loss(voltage threephase unbalance), reverse phase. 3. Phase loss protection means that when the protected line is in the running state or nonoperating state, any phase failure occurs, and the delay is 2S. 4. Reverse phase protection, a protection measure to prevent L1, L2, L3 threephase AC phase sequence from being connected incorrectly, delay 2S action. 5. Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to threephase voltage imbalance. 6. Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, etc. Specification: Condition: 100percent Brand new Rated Voltage: 200500VAC , 5060Hz Protection Function: Phase failure and phase sequence Display Mode: LED Indicates working status Contact form: Two sets of normally open normally closed contacts Contact Capacity: 6A AC250V (resistive) Installation Method: 35mm Rail or device Size: Approx. 79 x 23 x 79mm 3.1 x 0.9 x 3.1in Package List: 1 x Protector Warning: This product is generally sampled on the power side of the threephase power supply and must not be installed on the output side of the variable current.
