Quality After-market AVR Replaces:

  • Caterpillar model VR6 (CAT 309-1019 or kit # 365-2076) 
  • Cat VR3 and Cat VR4 (Now obsolete and replaced by VR6)
  • Leroy Somer 202-8634 or 2028634
  • Basler AVC63-12B1
  • *KATO Engineering Model K65-12B (Part # 810-35334-00) 

*WARNING! The VR6-A can replace KATO model K65-12B, BUT - the KATO only senses 120V instead of 200-240V like the VR6-A, so the installer will need to be sure the VR6-A is wired to accept 200-240V sensing!! Most gensets that have 120V also have 208 or 240V available, so it should be rather simple to change if a qualified tech is doing the installation.
