Self-Hold thermal switch 7AM Series for Temperature Protection Product Description The Self-Hold 7AM Series Bimetal thermal switch combines
the protection of a Klixon 7AM with a self-holding feature.
Designed to prevent overheating in motors, the Self-Hold 7AM series
offers the best attributes of one shot protectors and auto
resetprotectors in a single package. The Self-Hold 7AM, once activated in a fault condition, maintains
its open state until power is removed. No reset button here-simply removepower and the device will cool
and reset.This inherent design feature adds an extra levelof
security over automatic reset devices of any type. It is the
reliable, cost effective solu-tion for numerous
applications. Each 7AM temperature rating has a bimetal disc
specifically manufactured for that rating. Each device is then
calibrated and checked for opening temperature. This results in
optimum snap–acting open and reset characteristics necessary to
achieve consistent performance over the required cycle life. Maximum Contact Ratings 16 VDC at 20 amps 120 VAC at 22 amps 277 VAC at 8 amps 600 VAC at 4 amps Maximum Ambient Temperature Continuous: open-temperature +10°C
Features of Self-Hold Bimetal thermal switch 7AM Series for Temperature Protection Recognized component in ULproduct category XCSZ2 Overheating protection for motors Tested to UL standard 2111 18 day locked rotor test limited short circuit test 10 cycle locked rotor and 50cycle endurance test 0°C ambient test· Miniature size. Reliable temperature performance over the life of the device. Both current and temperature sensitive for maximum design
flexibility. Short lead time. Customized leads. ROHS compliant. 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. Temperature Ratings Table Open Temperature: 65°C to 175°C in increments of 5°C(Temperature Tolerance: ±5°C)
