The Series 30000 ThermoSwitch® is an adjustable temperature controller. This electromechanical controller has an on-off differential of ±1°F (±0.55°C). Designed for industrial and commercial applications, these controllers require no external power source and respond rapidly to temperature changes. The controllers are installed in direct contact with the heated surface, allowing temperature changes to be sensed quickly. They offer a narrow temperature differential and are UL component recognized for a minimum contact life of 100,000 cycles. They are fully adjustable, with overlapping ranges from 50° to 600° (10° to 315°) and a 10-A (1,200-W) resistive load rating at 120 vac. According to the company, it has established global manufacture of the surface-mount ThermoSwitch temperature controller, stating that close temperature control in a surface-mount thermostat is an important design choice.
