Here's how the Self-Hold 7AM functions. . .
• Developed by Thermtrol, the Self-Hold 7AM is a Thermal Protector/PTC Heater combination. The PTC Heater is electrically located across the contacts of the protector.
• When the protector contacts are open, the heater is in series with the load. The heater then maintains the temperature sensitive bimetal of the protector in an open state.
• To reset the Self-Hold 7AM, power must be removed for sufficient time to allow the Self-Hold 7AM to cool to below the protector's reset point.
APPLICATIONS
• Countertop appliances
• Medical equipment
• Lighting
• Battery chargers
