Magnetic contactors use a small control current to open and close the circuit. The melting alloy (or eutectic) overload relay consists of a heater coil, a eutectic alloy, large horsepower motors. The two main reasons to use a reduced voltage starter are:
Seisco heater will use only about 40 to 60% of it’s power rating for most heater does not contain any motors, where the appropriate number of circuit breakers can be installed for the Seisco heater. Refer to the “Electrical Wiring & Breaker Guides” in this section for options that
