FEATURES •Relay complies with IEC 61810-3, Type B and with IEC/EN 60335-1 (GWT) •Overvoltage category as per IEC 60664-1 III / 4kV •Rated voltage as per IEC 60664-1 basic insulation This SF relay design ensures thatsubsequent operations shut down andcan automatically return to a safe statewhen the SF relay suffers overloadingand other circuit abnormalities(unforeseen externally caused circuit ordevice breakdowns, end of life incidents,and noise, surge, and environmentalinfluences) owing to contact welding,spring fusion or, in the worst-casescenario, relay breakdown (coil rupture,faulty operation, faulty return, and fatigueand breakage of the operating spring andreturn spring), and even in the event ofend of life.
