SEV250
SANYOURELAYS
Relays for advanced technology
●200 amps continuous carry,2000 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.
●With energy-saving coil circuit ,the nominal power is only
2.0W,broad coil voltage:12~24VDC.
●RoHS compliant.
