5.9  HEATER CONTACTOR & PUMP MOTOR STARTER

A.

 

The “standard” mechanical contactor for the heater will cycle proportionally to the amount 

of heat input required for the process and may cycle frequently.

B.

 

This is a “wear” item that must be routinely inspected and replaced when the contacts 

begin to indicate wear/pitting.

C.

 

Failure to maintain the contactor may result in overheating of the components and 

catastrophic electrical failure.

 

D.

 

The “standard” mechanical pump motor starter must also be routinely inspected and 

replaced when the contacts begin to indicate wear/pitting.

Typical electrical panel.

Typical Heater Contactor

Typical Pump Motor Starter

WARNING:

  

Failure to maintain the contactor may result in overheating of the 

components and catastrophic electrical failure.
