klixon 3MP+PTC overload protector for motor power-off reset

● 3MP+PTC current overload protector (with power-off reset function)
PTC self-sustaining function: When the overload trips, it can be automatically turned on after cutting off the power supply.
With delay protection function. It is produced with the proprietary technology of Texas Instruments KLIXON ® in the United States.

The working design principle is as follows:
(1) The 3MP thermal protector forms a parallel circuit with the PTC, and then is connected in series with the load (محرك). The PTC will not generate high temperature when the load is operating normally.
(2) When the load is abnormal, the high temperature or large current will cause the 3MP thermal protector to open circuit. At this time, the PTC element will generate high temperature (the high temperature of the PTC will keep the 3MP thermal protector in the open circuit state), and the load will stop running.
(3) When the power is manually disconnected, the PTC begins to cool down and cools down after a certain period of time.
After the 3MP thermal protector contact is reset, the power is turned on again and the load runs.

(2) Advantages:
● KLIXON ® brand sensors and controllers produced by the Sensata Technology Factory established by Texas Instruments in the United States. This famous brand has a history of more than 90 سنين. It produces the most complete varieties of sensors and controllers, the largest output, top quality, low price and high quality, and the quality is guaranteed by credit. (Products have manufacturing plants and research and development centers in Asia, Europe and the United States)
● The factory has an advanced kinetic energy laboratory, which can according to the performance of the customer’s motor… إلخ. Provide customers with the best 3MP thermal protector sample selection and application testing services, and provide test reports upon request.
● 3MP thermal protector is suitable for protecting 125V and 250V AC motors or transformers under overload, blocked rotor, or short circuit and overcurrent conditions. The overload trip current value can be set according to customer requirements, up to 30 أ (ampere).
● With power-off protection and delay protection functions
●Provides a higher level of protection for equipment with rotating parts;
●More suitable for abnormal protection of motors.
● Passed safety certifications from various countries: UL, وكالة الفضاء الكندية, VDE, ENEC (EU), KEMA, CQC…certificates, and complies with EU ROHS environmental protection requirements.
(I) Characteristics:

● 3MP current and temperature double protector is a protection element with dual protection functions of over current and temperature. It can quickly control the damage of the motor due to stalled motor or excessive current. It is produced by Texas Instruments KLIXON ® proprietary technology.

The working design principle is as follows:

(D) Principle of high current overload protection:
The auxiliary heating piece in the 3MP thermal protector is matched with the bimetal piece. It has the function of quickly controlling the overload current trip time. When the (محرك, محول …) is over-current or the stall current exceeds the trip value set by the thermal protector, the protector can instantly cut off the circuit to protect the appliance. (Design range of tripping value of current overload: 3A ~ 30A)

(5) Temperature protection principle:
3MP thermal protector can quickly control appliance temperature. The current passes through the KLIXON ® bi-metal thermostat. When the electrical appliance does not work properly and the surrounding temperature is too high, the bi-metal of the thermal protector quickly disconnects the silver contacts to protect the appliance. When the thermal protector cools to a safe temperature, the contacts are automatically closed and reset. (Trip temperature selection range: 80 ℃ ~ 170 ℃)

3النائب (self-contained) current overload protection overheating protection and precise control of current overload protection function of time, turn off the power again after turning (with manual reset function), it ensures a higher level ——– security.
