英文资料：
The ABB T3N225 circuit breaker is a medium-sized circuit breaker from the ABB T3 series, designed specifically for overload and short-circuit protection in low-voltage power systems. It is widely used in industrial, commercial, and building power distribution systems to ensure effective protection of electrical equipment and lines in the event of faults.
Main features and technical parameters
Rated current (In):
The rated current of ABB T3N225 circuit breaker is 225 A, suitable for electrical protection under medium loads.
Overload protection and short circuit protection:
Overload protection: It can be set according to the actual load situation to prevent excessive current from causing overheating and damage to the circuit and equipment.
Short circuit protection: This circuit breaker is equipped with a short circuit protection function, which can quickly disconnect the circuit in case of a short circuit, preventing more serious faults from occurring.
Circuit breaking capability:
T3N225 has high breaking capacity and can handle high short-circuit currents, ensuring that the current can be quickly cut off in extreme situations to prevent electrical equipment damage or fire.
Electrical performance:
Instantaneous trip: When a short circuit fault occurs, the instantaneous trip feature ensures that the circuit breaker disconnects the circuit in a very short time, protecting the system from damage.
Time delayed trip: For smaller overloads, the T3N225 circuit breaker supports a time delayed trip feature, which helps prevent unnecessary trips due to short-term overloads (such as starting currents).
