Биметаллический мгновенного действия, Самоудерживающийся дисковый термостат с кабелями

Биметаллический мгновенного действия, термостат самоудержания для двигателей и бытовых приборов. В аварийном состоянии, the Model 7AM, 6AP opens the circuit, и внутренний источник тепла удерживает его открытым до тех пор, пока не будет отключено питание., и агрегату дают остыть. Затем термостат сбрасывается, позволяющая продолжить работу. Функции.

China’s innovative Self-Hold 17AM / VA / 8СМ / 6АП / 8ЯВЛЯЮСЬ / 2AM Bimetal thermal protector combines the protection of a Klixon® 17AM with a self-holding feature. Designed to prevent overheating in mo- tors, the Self-Hold 17AM offers the best attributes of one shot protectors and auto reset protectors in a single package. The bimetal Self-Hold 17AM thermostat, once activated in a fault condition, maintains its open state until power is removed. No reset button here-simply remove power and the device will cool and reset. This inherent thermostat design feature adds an extra level of security over automatic reset devices of any type. It is the reliable, cost effective solution for numerous applications.

Here’s How it Functions
Developed by China YAXUN, the Self-Hold 17AM 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 17AM motor thermal protector , power must be removed for sufficient time to allow the Self-Hold 17AM to cool to below the protector’s reset point.

Bi-metal Options
Self-Hold 17AM motor thermal protector performance is dependent upon the applied current as well as temperature. Differenct Bi-metals are incorporated to achieve various performance characteristics. In applications where temperature rise is less than 2°C per second, use low-resistance ratings. High-resistance Bi-Metal is recommended for applications with 2°- 5°C per second rates of temperature rise. Contact YAXUN for additional application consideration if the rate of temperature rise exceeds 5°C per second. Use these curves to determine which Bi-Metal may trip in the manner required for your application.

Leads
YAXUN’s state-of-the-art automated lead processing equipment can produce lead wires to meet customer application needs for overall length, wire type, wire size, terminated connection and stripped length requirements. Standard lead size is 18AWG. 20AWG-14AWG is also available.

Sleeving
In order to achieve optimum heat transfer from the protected medium or ambient to the Self-Hold thermostat, the Self Hold 17AM has been designed with the case connected to the bimetallic disc. This feature makes it necessary to electrically insulate the 7AM/17AM from the mounting surface. Обычно, this is accomplished with a sleeve marked with the part number. Custom markings and other sleeve materials are available.

Self-Hold Disc thermostat maximum current
The maximum current rating is the maximum electrical load in amperes that the contacts of the electrical switch is designed to carry.

Self-Hold Disc thermostat maximum voltage
The Self-Hold thermostat maximum voltage rating is the greatest potential difference that the device is designed to hold across open switch contacts without arcing or development of a current. The maximum voltage is specified for alternating-current (AC) and direct-current (DC), with AC exhibiting a greater self-extinguishing tendency of an arc across an air gap and therefore able to hold a greater potential difference.
