Wattage

Wattages other than those listed are available. Consult factory.

Voltage

Standard voltages are either 120V or 240V. Other voltages are available.

Tolerance

Wattage tolerance is +5%, -10% at rated voltage.
Diameter is always .001″ less, but not more than .009″ less, than the nominal (fractional) heater diameter.
Length tolerances are ±2% with a ±1/16″ minimum. Should tighter dimensions be required, Backer Hotwatt can provide closer control.

How to Order

After determining the wattage required and the line voltage available, determine the physical space available for heaters and the numbers of heaters required.
Review Special Features.
Specify: Catalog, number, wattage, voltage, lead length, and special features if required.
Example: MS17.5-110/400W/220V/SF1-6
