The T1N 160 family is documented by ABB with 3-pole versions and thermal-magnetic trip units. However, the specific trip-unit code should not be attributed to this individual unit based solely on the photographed nameplate unless the corresponding marking is present.

⚡ Breaking Capacity

The nameplate indicates the following Icu values:

• 230 V AC: 50 kA
• 400/415 V AC: 36 kA
• 440 V AC: 22 kA
• 500 V AC: 15 kA
• 690 V AC: 6 kA

For Ics, the nameplate indicates:

• 75% of Icu at 230 V and 400/415 V
• 50% of Icu at 440, 500 and 690 V

The nameplate also provides DC ratings with the poles connected in series, according to the wiring diagram indicated on the label. These values are consistent with the ABB technical documentation for the T1N 160.

🔧 Operation and Protection

The Tmax T1N 160 is designed for protection of electrical lines against overcurrents and short circuits, as well as for manual opening and isolation of the circuit.
The front rotary control allows the breaker to be placed in the following conditions:

• ON: circuit closed
• TRIPPED: protective trip condition
• Open/isolation position: according to the device configuration

The TEST button visible on the front allows the verification procedures provided for the specific configuration of the circuit breaker.

🏭 Construction and Installation

The compact molded-case construction is designed for installation in industrial electrical switchboards and low-voltage distribution systems.
The front terminals are designed for copper conductors, and the label specifies a tightening torque of 7 Nm. The photographed configuration does not show accessories connected in the SOR, UVR, AUX and MOS positions indicated on the nameplate; therefore, no accessories are attributed to the unit unless they are clearly present.

🌐 Applications

The 160 A Tmax T1N 160, depending on the installation configuration and electrical system characteristics, can be used for:

• Industrial electrical switchboards
• Distribution line protection
• Power-circuit isolation
• Industrial machinery protection
• Automation and distribution panels
• Electrical systems with voltages up to 690 V AC
• Industrial applications requiring high rated current and appropriate short-circuit breaking capacity

🛡️ Safety and Product Condition

The component is used and shows normal cosmetic and usage marks visible in the photographs, consistent with previous installation.
Before recommissioning, professional inspection is recommended, including at least:

• Terminal condition inspection
• Verification of correct operating-mechanism movement
• Trip and reset operation check
• Insulation testing
• Pole continuity testing
• Verification of the trip-unit characteristics
• Functional testing under controlled conditions, where appropriate

Electrical performance must not be considered verified solely on the basis of the photographs. The device must be installed and tested by qualified personnel in accordance with the voltage, current, and short-circuit ratings applicable to the installation.
