Voltage
Standard voltages are either 120V or 240V.
Other voltages are available.
Tolerances
Wattage tolerances are held to +5%, -10%
at rated voltage. Length tolerances are ±2%
with a ±1/16" minimum.

How to Order
After determining the wattage required and the line voltage available, determine the physical space available for heaters and
the number of heaters required. Review Stock list for In-Stock Items.
Specify: Catalog number, wattage, voltage, lead type, bushing type, and special features if required.
