Combination control consists of gasketed plastic enclosure, thermostat, contactor and optional control transformer. To omit step-down transformer, add "LT" to end of model number. Thermal Protection Systems**

Product Features and Benefits:

IMPROVES PROCESS CONTROL: Large (.56" high), easy to read LED display. Two set points (heating and cooling). Provides precise control for consistent plating and etch rates in most aqueous processes.

TEMPERATURE SENSOR: Fluoropolymer (FEP) covered 10-foot (3m), 1000-ohm platinum RTD sensor included standard with the control. Provides extended service in corrosive liquids and can be lengthened with ordinary copper hookup wire.

CORROSION RESISTANT ENCLOSURE: NEMA 1, IP23, gasketed plastic enclosure with sealed tactile switches and stainless steel hardware.

CERTIFICATIONS: cUL.

CAPACITIES:

•	Large switching capacities from 30 to 150 amps for either 240 or 480 volts (other voltages available).
•	Single pole, double throw switch rated at 2 amps for cooling loads.
•	Adjustable temperature range from -40�F (-40�C) to 999�F (538�C).
•	+/- .25% full span, single digit accuracy.
•	20�F (-7�C) to 130�F (54�C) ambient temperature range.
•	Programmable standby temperature setting for overnight control and energy savings.
•	120, 208, 380, 415, 600 and other voltages available.
•	Single or three phase.
