ABSTRACT:
An electrical furnace heater construction having electrical heaters carried by a frame and having a current fused drawer-like lead unit movably carried by the frame and having leads for directly and electrically interconnecting to terminals of the heaters when the unit is in one position relative to the frame, the frame having terminals for electrically interconnecting the leads of the unit to power source leads so that the power source leads will be directly and electrically interconnected to the terminals of the heaters by the unit. A temperature responsive power device is carried by the frame and is responsive to the output temperature effect of the electrical heaters, the temperature responsive power device being operatively associated with the unit to move the unit out of the one position thereof to disconnect the leads thereof from the terminals of the heater when the temperature responsive device senses a certain adverse output temperature effect of said electrical heaters.
