Feature
SANYOURELAYS
Relays for advanced technology
●40 amps continuous carry,400 amps interrupte under
extreme condition.
●Hermetically sealed with hydrogen gas,the arc is not exposed.
Be able to use in explosive & harsh environments without
oxidation or contamination of contacts.Contacts' part meet
IP67 protection degree.
●Not position sensitive- can be mounted in any position for
ease of installation.
●RoHS compliant.
