Vacuum Relays, DPDT types
Gigavac G23WF DPDT vacuum relay
These are the heaviest-duty vacuum relays we have EVER seen in this (DPDT) contact configuration! Each of the two sets of contacts are rated 75 amps, and 20kv (23 kv peak)! This IS an RF rated relay! Brand new, unused stock. Many of our customers have paralleled the two sets of contacts to double the current-handling capability of this relay, effectively yielding a SPDT configuration at 150 amps! Absolutely unbeatable capacity / performance for the price!
Ceramic body for extra ruggedness and current handling capability. Flange mount type (3 mounting slots). These are physically fairly large, as shown in the accompanying photo with a US one dollar bill for size reference. For manufacturer's data sheet, click here: http://www.gigavac.com/products/relays/datasheets/g23/
Diameter, not including terminals, is 1.5 inches. Diameter of flange is 2.44 inches. Height, (overall) is 4 inches. Weight is 380 grams, or 14 ounces . Terminals are drilled and tapped, and are furnished with mating screws. This is THE choice for the most extreme high-power applications where double pole, double throw contacts are required. Furnished with 26 vdc coil, (240 ohms). Note: An optional 12 vdc coil (60 ohms) is also available for this relay, and is normally a stocked item for only $25.00! (If you wish, we can install the 12VDC coil at no additional charge. ask.) Mfr's list price of relay: $671. By means of a special purchase, we have an unbelievable price on this relay. far too low to publish!

Gigavac G2SPD DPDT vacuum relay
These new relays by Gigavac are a perfect replacement part for the popular Kilovac H-16 and the Jennings RB-3 double pole, double pole relays, which have recently been very difficult to find due to the military's policy of destruction of all electronic surplus. The new Gigavac G2SPD is an improved version of the Kilovac H-16 and the Jennings RB-3, in that the ratings of both sets of contacts are 50 amps instead of the 30 amp ratings on both of the glass relays, and the peak voltage rating on BOTH sets of contacts on the Gigavac is 15 kv , as opposed to 12 kv on the top contacts and 6 kv on the bottom contact on both of the glass relays.
Gigavac accomplished this by using rugged ceramic construction, and by the larger spacing between the bottom set of contacts and the chassis. (See the larger diameter ceramic band at the base of the Gigavac relay.) Contact terminals are solder-pot type, for direct soldering of wire conductors. Overall height above the chassis is 3/4 inch taller for the Gigavac compared to the Jennings and the Kilovac types. The coil (which extends below the chassis) is shorter on the Gigavac than on the Kilovac and Jennings.. threaded portion is about 5/16 inch long on the Gigavac, and about 3/4inch on the Kilovac and Jennings.
Supplied with threaded base mount, with two mounting nuts and lock-washer. Standard coil is 26.5 vac, and is 285 ohms. A 12 vdc coil (60 ohms) is also now available as an option. If you need 12 vdc coil, please specify. Rated 20 milliseconds operate time, 8 milliseconds release. 1,000,000 operations rated life.
Weight is 1600 grams, 5.7 ounces. Height overall is 3.37 inches. Threaded base is 1.125 inches diameter. Link to manufacturer's data sheet is here: G23SPD.pdf
Photos illustrate a Kilovac glass DPDT relay, type H-16, (orange label) for size reference only as compared to the white ceramic Gigavac G2SPD. (Jennings RB-3 is almost the identical size as the Kilovac.)

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.
