Patent abstract

A ballast having fused leads protects against uncommon, but harmful, ballast failures. The fused leads prevent a current in the primary coil of the ballast from exceeding a potentially damaging value. A thermal protector shorts the primary ballast coil if the temperature of the secondary ballast coil exceeds a potentially damaging value. Since the thermal protector permanently disables the ballast, potentially damaging repetitive overheating of the ballast is prevented.
