Lucas Electrical Contactor
28V 125 Amp
Complete with Plug
Spares recovered from a Tornado aircraft
This item has been tested recently by an ex RAF Electrician. Found to be in full working order.Test Results as follows:
“Was run up to 175 Amps for ten seconds showing a maximum of 82mVolts (0.082V) volt drop across the contacts. Test repeated 3 times no detectable temperature rise in the contact assay.
One sweet little contactor
Pull in 13.7Volt drop out 6.6Volt
The contact structure is in immaculate as new condition.
From the internal dimensions I would rate it at 225A max continuous given a normal current density norm of 3KA per Sq inch.
However the coil has a resistance of approx 48 Ohms so is intermittantly rated on 28V disipating 16.3 watts.
Over a 7 minute soak the coil temp got to 47Deg C so not suitable for continuous duty on buss control.”
Condition: Good used as removed condition as per photograph.
Few marks and scratches from standard service use.
