Start Capacitor With Resistor

Find dry electrolytic nonpolarized start capacitor models in a wide range of sizes and mfd ratings.

Start capacitor with resistor.

If damaged or not provided install a new resistor and clean the relay contacts or replace the relay. The important part is if your original capacitor had one you ll need to replace it on the new capacitor. View our full line of start capacitors. When you need motor start and run capacitors shop at grainger.

The purpose of the resistor is to bleed off residual voltage in the capacitor after it has been disconnected from the circuit after motor start up. When you need motor start and run capacitors shop at grainger. Suitable resistors can be obtained from any electronic parts wholesaler or retailer. Round molded cases can protect start capacitors from oil dirt moisture and grease helping prolong maintenance free performance and reduce replacement costs.

If sticking contacts are encountered on any start relay the first item to check is the start capacitor resistor. A start capacitor resistor also called a bleed down resistor is used to bleed off residual voltage in a start capacitor after it has removed from a motor circuit after start up. Round molded cases can protect start capacitors from oil dirt moisture and grease helping prolong maintenance free performance and reduce replacement costs. The damaged contacts could be caused by the high voltage stored in a start capacitor being discharged across the contacts of a start relay.

Not all start caps use resistors as there are other ways to accomplish the task of reducing residual voltage in a capacitor. 330v start capacitor 270 324 mfd with resistor prmj270r 330v start capacitor 270 324 mfd with resistor. A start capacitor resistor also called a bleed down resistor is used to bleed off residual voltage in a start capacitor after it has removed from a motor circuit after start up. This one covers testing of the start capacitor.

Find dry electrolytic nonpolarized start capacitor models in a wide range of sizes and mfd ratings. 2 watt 15k ohm bleed resistor primarily used with start capacitors universal resistors with 1 4 female quick connect terminals. Copeland electrical handbook p a5 a6. To eliminate this potential problem there should be a bleed resistor across the terminals of the start capacitor.
