Replacement Coils  

When a vacuum relay fails, it is of course very rare for both the removable coil and the contact set to both fail at the same time. Lightning damage is normally the only cause of simultaneous failure. The coil is easily removable by means of a screw or nut on the very bottom of most vacuum relays. This leaves the contact set (with contacts still sealed in a vacuum). The failed component can be easily replaced at well less than the cost of an entire new unit.

We have a good assortment of coils (All are 26.5 vdc coils unless specifically noted otherwise.) If you do not see the coil you want, please feel free to call or email with your needs. We frequently have additional coils that are not shown here.

Kilovac H-8 coil..........$12.50

Jennings RB1D coil.........$12.50

Jennings RE6B coil.....$29.00
