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 common protective device used in series with a load is a fuse. More complicated ones include capacitors and other stuff that goes into surge protectors.
