210 Series
Dividohm Vitreous Enamel Adjustable Power Resistor. 15.0 Ohm 25W Solder Tabs.
 Ohmite’s 210 Type adjustable resistors for applications requiring settings at different resistance values. 

These wire wound resistors are equipped with an adjustable lug, making them ideal for adjusting
circuits, obtaining odd resistance values and set-
ting equipment to meet various line voltages. 210
Type resistors feature a hollow core to permit secure
fastening with spring-type clips or thru bolts with
washers. They also offer the durability of
vitreous enamel coating and all-welded construction.
Mounting brackets not included with resistors.

Adjustability 10% to 90% of full value. Wattage is proportional to this adjusted
resistance value.

Coating vitreous enamel.

Core Tubular ceramic.

Terminals Solder coated radial lug.

Adjustable terminal

Nickel plated steel. (Screwdriver type adjustable lug supplied
standard.

Derating Linearly from 100%  at +25°C to 0% at +350°C.
Tolerance ±10% (K)

Power rating Based on 25°C free air rating. The stated wattage rating applies
only when the entire resistance is in the circuit. Setting the lug at
an intermediate point reduces the wattage rating by approximately
the same proportion. Example: If the lug is set at half resistance,
the wattage is reduced by approx. one-half.

Overload 10 times rated wattage for 5 seconds.

Temperature coefficient ±260 ppm/°C

Dielectric withstanding voltage 1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 and 225 watt rating (measured from terminal to mounting bracket)

Max. amps To calculate, use the formula √P/R
