Pole-and-throw specifications
Single pole, 한 번 던지기 (SPST) switches make or break the connection of a single conductor in a single branch circuit. They have two terminals and are commonly referred to as “single pole” switches.
Single pole, double throw (SPDT) switches make or break the connection of a single conductor with either of two other single conductors. Often called “three-way switches,” SPDT devices have three terminals and are used in pairs.
Double pole, 한 번 던지기 (DPST) switches make or break the connection of two circuit conductors in a single branch circuit and usually have four terminals.
Double pole, double throw (DPDT) switches make or break the connection of two conductors in two separate circuits. Most DPDT switches have six terminals and are available in either momentary or maintained contact versions.

Creep-Action Thermal Protectors with more than two poles are designed to split loads into separate circuits.

Creep-Action Thermal Protectors Set-point Temperature
Creep-Action Thermal Protectors Specification Guide Thermal switches and thermal protectors have a set point temperature that is either fixed or field adjustable. 설정점은 장치가 전기 접점의 움직임과 관련된 상태 변화를 겪는 정격 온도입니다.. 고정점 장치는 주어진 온도에서 정격이 지정되는 반면, 현장 조정 가능 장치는 설정점을 조정할 수 있는 온도 범위를 갖습니다..

Creep-Action Thermal Protectors Hysteresis
히스테리시스, 온도차라고도 함, 스위칭이 일어나는 유한한 온도 범위. 회로가 상태 간에 지속적으로 변경되는 것을 방지하도록 설계되었습니다.. 히스테리시스 0.5 C는 일반적으로 작동합니다 0.5 설정점 온도보다 0.5도 낮고 온도가 설정점 온도보다 0.5C 낮아질 때까지 상태를 다시 변경하지 않습니다..

주변 온도: The normal or typical temperature of the environment surrounding the device.

자동 재설정: A thermostat that automatically resets to its pre-trip contact configuration at a factory preset temperature.

바이메탈: Two metals with different rates of expansion molecularly bonded together to form a blade or disc for a thermostat.

Creep Action Thermostat: A thermostat with a bimetal blade that slowly makes the contacts or slowly breaks the contacts.

Current Derating: Term used to describe a predictable condition where increased current applied to a thermostat causes the device to open at a temperature below its set point. This condition is present only in Normally Closed bimetal thermostats that are both current and temperature sensitive.

Functioning Temperature: (TF of Tf) In reference to a thermal cutoff, as defined by IEC Standards, the temperature at which a Thermal Cutoff opens a circuit under a no load condition. The IEC tolerance is +0 씨, -10 씨.

Holding Temperature: (TH or Th) In reference to a thermal cutoff, the maximum temperature that a Thermal Cutoff can maintain Rated Current for a period of 168 hours with functioning.

Maximum Temperature: (TM or Tm) In reference to a thermal cutoff, the maximum temperature to which the device can be subjected for a period of ten minutes without resuming conductivity once it has opened.

Minimum Differential: (also known as deadband) The minimum number of degrees between the actual open and actual close temperatures.

Motor Protector: A thermal protector that is sensitive to both increases in current and increases in temperature.

평상시 닫힘 (N.C.): Contacts open on temperature rise.

평상시 열림 (N.O.): Contacts close on temperature rise.

One Shot: A device that, once activated at its preset temperature, cannot be reset. Available only in Normally Closed contact configuration.
정격전류: The maximum allowable current that a device can carry.

정격전압: The maximum voltage that should be applied to a device.

Self-Hold Protector: A device that, upon opening, will not reset until power is removed from its circuit regardless of ambient temperature. Available only in Normally Closed contact configuration.

Snap Action Thermostat: A thermostat with a Bimetal element that snaps to close the contacts when the activation condition is experienced. This construction permits the clean break of loads.

열 차단: A thermal cutoff is an electrical safety device that interrupts electric current when heated to a specific temperature.

Thermal Cutoff Fuse: A device that melts its internal element to open a circuit in an over-temperature condition. Also known as a thermal fuse, thermal protector fuse or thermal switch.

Thermal Protector: A Thermal Protector is a protective device built into a motor that provides over-current or over-temperature protection that disconnects power to the ballast if internal temperatures rise above the trip point. This protects motors from overheating. Types of switches include automatic rest, manual reset and resistance temperature detectors.

용인: The allowable range above and below a nominal temperature.
