Type C2: Standard Terminal Box (on flat pad)
Type C2 is an individual terminal box for protecting the terminals on each Cast-In Band Heater half and on many other Cast-In Heater designs with one set of heater terminals.
The C2 box design requires a flat pad on half-round castings or a flat surface on other casting designs for mounting. It is made from heavy gauge, rust-resistant sheet metal. The cover is removable for easy access to terminals. The box has two 7/8″ diameter knockouts opposite each other for standard 1/2″ BX connectors.
Type C7: Terminal Box attached to Clamping Straps
Type C7 terminal boxes are made from rust-resistant sheet metal. The C7 base is fixed to the clamping straps. The box has two 7/8″ diameter knockouts opposite each other for standard 1/2″ BX connectors. The cover is removable, providing easy access to the screw terminals for electrical wiring.
Type P2: Quick Disconnect Plug Assembly with Box
Quick-Disconnect Cup assemblies provide the simplest and safest means for applying power to any type of Cast-In Heater installation. The box extends over the screw terminals on both Cast-In Band Heater halves. The combination of prewired cup and box assembly, along with factory prewired high temperature lead wire protected with armor cable, eliminates live exposed heater terminals and electrical wiring, protecting employees from electrical shock and the possibility of electrical shorts due to exposed wiring.
Type EP: Explosion & Moisture Resistant Box
Cast iron explosion and moisture resistant boxes should be used in areas where the surrounding air may become contaminated with combustible gases or a high humidity level may exist. Installation requires one box per Cast-In Heater half and they are brazed to the tubular heater. The standard box has one 1/2″ NPT hub.
Type MPR: Moisture Resistant Box
This design has a moisture resistant die cast aluminum box with a non-removable polyurethane gasket in the lid. Lid is secured with captive stainless steel screws. Body and lid are painted in basic industrial gray; interior contains copper ground screw. Box is mounted to a plate that is brazed to the element. Available in a wide variety of sizes.
Type MR1: Moisture Resistant Box with Shield
This design incorporates the MPR housing style along with a perforated tube shielding unheated extensions of the tubular heating elements. This feature provides mechanical strength to the element extension and prevents overheating of the terminals, reducing possible premature failure from corrosion and oxidation.
Type CB: Cast Aluminum Box
A Cast Aluminum Box is used to protect and secure lead wire terminations on narrower designs.
None
This Cast-In will not have Terminal Protection.
