EVSE 30A AC 220V Power Relay SPDT Sealed PCB QT250 Terminal NB901E-AC220S-S-C
AC Power Relay Features:
1. 4000VAC or 2500VAC is available for dielectric withstand voltage between contact and coil
2. Class F for coil insulation grade
3. Dust-proof or sealed type
4. NO. or NC.
5. Max 40A
AC Power Relay introduce:
A relay is an electrical control device, which is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity meets the specified requirements. It has an interactive relationship between the control system and the controlled system. Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
AC Power Relay Note:
1. Using under a clean environment(excluding H2S, SO2, NO2, dust contaminants), dust-proof type is recommended using under a polluted environment(containing H2S, SO2, NO2, dust contaminants), sealed type is recommended, and please contact us during practical application；
2. When assembly on PCB, it needs to be completely washed, please inform us before ordering, so as to provide the proper types;
3. If the dielectric strength between the coil & contacts has to be over 2500VAC, please inform us before ordering, so as to provide the proper types.
4. Avoid using it under strong magnetic or shock extremes conditions, or the technical rating will be changed.
