Because something is wrong.
Check for shorts and, if it is a GFCI, also check for ground faults and leakages. It is also possible, in the case of a GFCI, that an inappropriate load, such as a computer monitor or UPS, is connected. These devices pull transient power to ground and will trip a GFCI.
Do not ignore the situation. The protective device is tripping for a reason.
"Rated current" is the current the device (motor or transformer?) is designed to handle at full load. "Tripping current" is the current where a protective device (fuse, breaker) will open to protect the device from overload/overheating. "Tripped current", may be the current the tripping device measured prior to making the decision to trip, if you are reading this from a digital protective device like a relay or OCR.
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
in order to avoid equpement and damage.
an inverse time protective device is a protective relay with definite minimum operating current and definite minimum operating time for a given current. the device will ensure that increasing current in a fault, that the operating time will be decreased. Preventing an overload.
According to BS7671:2008, Requirements for Electrical Installations, an overcurrent protection device rated at either 30 A or 32 A is required.

Earthing is always required. It is necessary so that a fault or overvoltage, such as caused by a lightning strike, may be conducted to earth (ground), either dissipating the energy and/or tripping the protective device.
A fuse is the simplest protective device for over current in an electric circuit.
A circuit breaker may keep tripping due to overloading, short circuits, or faulty wiring.
To determine what is tripping your circuit breaker, you can unplug all devices on that circuit and then plug them back in one by one to identify the culprit. If the breaker trips when a specific device is plugged in, that device may be causing the issue.
Mimicry
The GFCI breaker may be tripping immediately due to a ground fault, which means there is a problem with the electrical wiring or a connected device that is causing electricity to flow where it shouldn't. This can be a safety hazard and the GFCI breaker is designed to trip to prevent electrical shocks or fires. It is important to identify and fix the issue causing the ground fault to prevent further tripping of the breaker.
Your house breaker may keep tripping due to overloading, a short circuit, or a ground fault. These issues can cause the breaker to trip to prevent electrical fires or damage. It is important to identify and address the underlying cause to prevent further tripping.

A Fuse
The GFCI may be tripping outside due to moisture, a faulty appliance, or a ground fault in the electrical system. It is important to identify and address the underlying issue to prevent further tripping.
