EXCLUSIVE BRACKET DESIGN
Mounting strap fits snugly through resistor core and is bound
against unit by two eccentric spacers. The bracket
eliminates expensive cements and improves heat transfer
and power handling capabilities.
NHL, NHLM NON-INDUCTIVE
Models of equivalent physical and electrical specifications
are available with non-inductive (Aryton-Perry) winding.
They are identified by adding the letter N to the front of the
HL and HLM type designation (NHLM-20, for example). For
NHL and NHLM models maximum resistance values are
lower, see STANDARD ELECTRICAL SPECIFICATIONS
