Old style electromagnetic dual coils relay cannot be found by many technicians. These were new extras, used for the electrical pole boxes of Georgia street traffic light signal 6volt lights many years back. Most nowadays are solid state replacement. These specialized relays were used in alternate energy tests due to exquisite properties. AC , 60 cycles, switching, latching, dual inductors, each about 1.5 Millihenry #21 gauge magnet wire, .7 ohm per coil, diode in between coils, coils each 1 3/4" by 3/4" with small core. The Bakelite outer black housing has no bracket, no markings, screw terminals on outside, and looks like an old vintage relay. Outer housing 3" long, 2" wide, and 1 1/2" high. The units are enclosed in VACUUM , so as will be extremely reliable in all weather conditions 24 hours a day, all year. When one was tapped and imploded, they are to be found with pivoting armature with 6 sets contacts inside. The alternate energy web site was closed down since no more than the original 15 can be found. When tested by technicians for hydrogen conversions, and other types did not work, they said they were worth their weight in gold. Search Please!
Please look at other vacuum relays, maybe they are also good:

I have something cooler here. Kilovolts and kiloamperes.
And so in general, almost all reed relays are vacuum.

I do not see contacts on your picture. Quite a monster, can you provide specification on it?
I have also something similar DD2566 Jennings
quite few.
Jennings vacuum interrupter Normally closed 125 amps 55kv
(70kv peak) 100 vdc actuator
$450.00 second hand

I don't know, to my shame. Yes, I held it in my hands and photographed it.
КДВ2 But already sold for silver. :( I think the mounting brackets are the contacts.
There is no electromagnet, mechanical drive. Used in electrical substations.

stivep,
Looks like a outlet box you can buy from Lowes or Home Depot, simple relay box I can make for pennies and sell it to you for $450.00
LOL

It is a vacuum relay. Never used, certified, military grade.
The original price for it per piece , was around $6800 "on that money" in 1990-
I'll keep it to build more powerful device I have.

I think such monsters will be difficult to handle.
Normal small vacuum relays, more suitable for those described in the first message:

It is not clear what function the relay should perform. If it is necessary to create many pulses 60 Hz with a mechanical switch, then you can look at such ancient devices:
https://www.ebay.com/sch/i.html?_nkw=DC-AC+Chopper (https://www.ebay.com/sch/i.html?_nkw=DC-AC+Chopper)
But this devices mostly are for very low switching power.
Russ mentioned small engine
3-4000 rpm ( cycle speed of relay contacts
High voltage (car ignition ...maybe higher voltage "plasma" as per some water fuel claims ?
Nothing there that should not be impossible to find in vacuum relay ( double solenoid? Perhaps exotic metal on contacts?
Interesting if this component is make or break on it working?
The high quality vacuum sealed dual coil relays , per cylinder, operated various engines at a lowered 700 rpm of idling engines back 2005-2013. There was no cycling of 6 sets relay contacts as a vibrator. There were 3 possible flows of voltage/current "paths" through relay depending on certain click position of internal pivoting armature. This tech data was from the now shut down web forum. The latching type relay would initially be one position. If engine not start, a retest is done for other position. About 38v half wave DC 6-7 amps passes through 2 inductors, ALONG WITH high volts passing through OPEN contacts as the necessary accessory spark gap, then 2nd inductor, and series diodes to output. When spark plug fired, the accessory current follows through. Small Hydrogen Gas and WATER VAPOR PRESSURE operates engine at greatly retarded timing. A return necessary special line to power supply ground is made for each of 1-8 spark plugs grounds as soldered wire to thin copper washer under plugs. AI computer agreed about the idea that inductor L - series diode - Inductor L -diode output may provide a much higher- superimposed minimum 100v back EMF over the 38v. The 4 techs back then believed that 100v and 6-7 amps were necessary to run engine on water in the carb, to compensate for the electrolysis of tiny small electrodes of spark plugs. Back EMF (each coil) E = L Henries X I / dt Dt = spark fast pulse time as also extended by inductance included to .029second. Inductors inside relay as each about .0015 Henry , .7ohm.
