ABB T3N225 is a typical model of the Tmax series molded case circuit breaker launched by ABB.It is widely used in industrial,commercial and power systems for overload and short-circuit protection.The following is a comprehensive analysis of its core parameters,application areas and selection points:
I.Core parameters
Rated current and breaking capacity
-Rated current:up to 225A,frame current 225A,support overload protection.
-Breaking capacity:
-Rated ultimate short-circuit breaking capacity(Icu):depending on the model,the range is 25kA to 50kA(for example,the Icu of T3N 225 UL/CSA TMF225-2250 is 25kA).
-Rated operating short-circuit breaking capacity(Ics):usually 50%-75%of Icu.
Electrical characteristics
-Rated voltage:690V AC/500V DC,suitable for medium and high voltage systems.
-Arc extinguishing medium:compressed air or vacuum(some models),strong arc extinguishing ability,suitable for frequent operation.
Structure and certification
-Frame type:plastic shell,double insulation design,in line with IP20 protection level.
-Certification standards:UL/CCC,IEC 60947-2,support global application.
2.Application fields
Industrial automation
-Protect production line equipment to prevent overload and short circuit damage to motors,transformers and other equipment.
Power distribution system
-Key protection components in main distribution and sub-distribution to ensure safe power transmission.
Commercial buildings
-Core components of distribution cabinets to ensure stable operation of lighting,air conditioning and other systems.
Energy industry
-Distribution equipment used in oil,natural gas and other fields to resist high current shocks.
3.Selection points
Breaking capacity matching
-Select the Icu value according to the expected short-circuit current of the system,which must be greater than or equal to the calculated value of the line.
-Cooperate with the upper circuit breaker to achieve selective protection and avoid over-tripping.
Selection of release type
-Thermal magnetic release:suitable for conventional power distribution,providing overload and short-circuit protection.
-Electronic release:supports current regulation(such as T3N 225 UL/CSA TMF125-1250),suitable for scenarios where protection parameters need to be flexibly adjusted.
Number of poles and wiring method
-3P/4P:selected according to the three-phase or four-phase system,the 4P model also includes neutral line protection.
-Front wiring/fixed installation:adapt to different distribution cabinet layout requirements.
IV.Installation and maintenance
Installation specifications
-Adjust the bolt torque according to the instructions to ensure that the contact resistance meets the standard.
-It is forbidden to power on when the pole is not installed or when no operation is performed.Before operation,it is necessary to confirm that the mechanism is connected reliably.
Maintenance recommendations
-Regularly check the operation counter,spring energy storage and opening mechanism lubrication.
-Use a thermal imager to detect overheating of contacts to avoid failures due to aging.
