Electrical ratings and compliance marks decide the shortlist. Both are structured fields here rather than claims in a description.
RoHS and REACH statements sit in marketing copy. Whether anyone reviewed the underlying test reports is usually unknowable from the outside.
Voltage, current, power, frequency and IP rating are platform-defined specs with fixed units, so a filter for 480 V three-phase returns parts that are actually that.
Spec searchVoltage, current, frequency and ingress protection are exactly the fields that decide fit, and exactly the fields a keyword search cannot reach.
RoHS, REACH and security certifications are filed with their issuer and evidence, and reviewed before they appear. A claim nobody has checked is not shown to buyers.
CertificationsAn inquiry sent into a contact form disappears. There is no way to know in advance which suppliers answer and which do not.
Every supplier's reply rate and typical response time are computed from real inquiries — counting only those they have had time to answer — and shown before you write to them.
