RITE-TEK H3L33A30 Cartridge Heater

RITE-TEK H3L33A30 Cartridge Heater is a cartridge-style heating element designed for insertion into equipment where a fixed-dimension heat source is required. It measures 3-1/4 inches in length and 1/2 inch in diameter, with a 240-volt electrical rating. The model number H3L33A30 identifies this particular heater within the H3L family from RITE-TEK, indicating its exact size and electrical characteristics for replacement or ordering. This form factor—slim, cylindrical sheath housing the heating element—fits into standard, pre-drilled heat zones where a 1/2-inch bore is specified, enabling straightforward integration in compatible assemblies that operate on 240 V. In procurement contexts, the H3L33A30 designation helps distinguish it from other H3L-series models with different lengths and diameters while preserving the same voltage class. Knowing the exact part number is essential for cross-referencing with supplier catalogs and ensuring correct fit during maintenance or replacement. The 3-1/4 inch length and 1/2 inch diameter are primary geometry criteria for compatibility in equipment designed to accept a cartridge heater of this size, while the 240 V rating defines the electrical class for safe operation in suitable systems.
