英文資料：
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).
Appearance and dimensions:
The T3N225 circuit breaker adopts a compact design, suitable for standardized electrical control cabinets and distribution panels, ensuring flexibility and convenience in installation and wiring.
The standardized size and installation hole spacing enable the circuit breaker to be quickly replaced or installed in existing systems.
Application scope:
Commercial buildings: used for power distribution systems in large commercial buildings to protect electrical equipment from overload and short circuit faults.
Industrial equipment: As the main power distribution and protection equipment in manufacturing factories, industrial production lines, and other places, it ensures the safe operation of important electrical facilities.
Residential power distribution: suitable for power distribution systems in large residential communities or multi story buildings, used to ensure the safety of electrical equipment and loads.
Power distribution and control system: T3N225 plays a critical role in the power distribution system, ensuring overload protection and short-circuit protection for each circuit in the system.
Durability and maintenance:
T3N225 circuit breaker has a long service life and good durability, suitable for environments with frequent switching operations.
This circuit breaker supports simple maintenance and inspection, and can be quickly replaced or repaired without interrupting power supply.
Environmental adaptability:
The circuit breaker design has strong environmental adaptability and can operate under harsh working conditions such as industrial environments and construction sites.
It can adapt to a wide range of working temperatures, typically from -5 ° C to 40 ° C.
