Overview of ABB T3N series Plastic-case circuit breakers
ABB’s T3N series MCCB is an important protection device in low-voltage distribution systems, suitable for AC 50Hz (or 60Hz), rated insulation voltage 690V, rated operating voltage 660V (or 690V) and below, DC 250V and below the circuit. They are mainly used to distribute electrical energy, make infrequent closing and breaking under normal conditions, and protect lines and equipment from overload, short circuit and undervoltage.

ABB T3N series plastic-case circuit breaker features
Protection function:
Overload protection: When the current exceeds the rating of the circuit breaker, the circuit breaker will delay to disconnect the circuit to prevent the device from overheating.
Short circuit protection: In the case of short circuit, the circuit breaker will quickly disconnect the circuit to prevent damage to the equipment and the line.
Undervoltage protection: When the voltage drops below the set value, the circuit breaker will disconnect the circuit to protect the motor and other loaded equipment from low voltage.
Operating performance:
Easy to install and maintain: compact design, simple structure, easy to install and debug.
High reliability: Using high-quality materials and advanced manufacturing processes to ensure long-term stable operation.
Extended features:
Accessories such as shunt release device and undervoltage release device can be selected to meet different protection and control requirements.
