Sealed NO. 4KV 12V 50 Amp Relay PCB Mount M4 Bolt Connect NB902-12S-S-A
12V 50A Relay Description:
NB902 series power relay, small size with big capacity, maximum 50A.There are PCB mounts and bolt quick connections for assembly,
special design for water heaters, air conditioners, etc.4KV dielectric withstand between coil and contact and passed TUV/CQC/UL
safety standard, it is an environmental-friendly and reliable product, be suitable for many fields, like the automobile industry, industry control
, home appliances, and medical equipment.
12V 50A Relay Features:
1. 4000VAC for dielectric withstand voltage between contact and coil
2. Sealed-type
3. SPDT & SPST
4. Rated current max 50A
5. 900mW or 1.2W
6. TUV/CQC/UL certification
12V 50A Relay Note:
1. Using under a clean environment(excluding H2S, SO2, NO2, and dust contaminants), a dust-proof type is recommended；
Using under polluted environment(containing H2S, SO2, NO2, dust contaminants), a 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.
