SPDT Power Relay Description:
NB903 series power relay, large switching capacity, maximum can reach 40A, the contact form has NO., NC, and SPDT to option.2.5KV or 4KV dielectric withstand voltage between coil and contacts, PCB mounting and QT connection both work. Sealed or dust-proof, TUV/CQC/UL is approved, also complies with RoHS-directive, widely use in industry, agriculture, automotive...
SPDT Power Relay Features:
1. 2500VAC is available for dielectric to withstand voltage between contact and coil.
2. Class F for coil insulation grade.
3. environmental-friendly.
4. 1 form C,SPST & SPDT.
5. TUV/CQC/UL certification.
6. Compliance with RoHS directive.
SPDT Power Relay Note:
1. Applying under a clean environment(excluding H 2 S, SO2, NO2, dust contaminants), dust-proof type is recommended; Applying under a polluted environment(containing H 2 S, SO2, NO2, dust contaminants), sealed type is recommended, and please confirm during practical application;
2. When installed on PCB, and entire washing is needed, please notify us before ordering, so as to provide proper items;
3. If dielectric strength between coil&contacts has to be over 2500VAC, please notify us before ordering, so as to provide proper items;
4. Avoid applying under strong magnetic or shock extremes, or the technical rating will change.
