	What is the purpose of fuseblock's rejection feature?
    

    
	A rejection feature is used to prevent fuses with a lower voltage or interrupting rating (such as Class H and Midget fuses) from being used in a circuit that needs a higher rating. Class R and CC fuseblocks incorporate a built-in rejection feature while Class J and T blocks reject based on physical size.
    

    
	    
    

    
	Will Class CC fuses fit in Midget fuseholders?
    

    
	Yes - Class CC fuses will fit in	o Midget fuseholders however Midget fuses will NOT fit in	o a Class CC holder due to the block's rejection feature.
