SPECIFICATIONS CLASS 389 RELAYS
The 300 series was developed as a 600 Volt relay that would accept 1/4" booted
terminals. Its extra spacing permits contact gaps to 2 millimeters when required.
This increases dielectric strength across open contacts to 2500 Volts RMS.
Consult factory for details or additional information.
