TEMPERATURE HIGH LIMIT SWITCH
As a safety device, an immersion high temperature cut-off switch with manual reset, adjustable through a range of 100° - 240° F, is provided. The high limit must be manually reset thereafter to restart the heater. Optionally a 1/16 DIN digital controller may be used as a high-limit.

MAGNETIC CONTACTOR
The magnetic contactor(s) is a heavy-duty resistive load type rated for 100,000 cycles. The contactor supplies power to the heating element(s) based on the resistive load (non-inductive) of the heater only when the thermostatic switch is engaged, thereby pulling in the contacts until the desired temperature is reached. At this point, the contacts will drop out, which in turn disconnects power from the elements.
FUSED LOW VOLTAGE TRANSFORMER
A fused low voltage transformer may be supplied. This option is used to step down higher voltages to 120-volt for safety when working with control circuits.
