3120-F311-P7T1-W14FR3-15A

Circuit breakers are safety devices designed to protect circuit overloads and short circuits by automatically disconnecting power. The 3120-F311-P7T1-W14FR3-15A is a type of circuit breaker that performs this role in a specifically designed application field and operates on a particular working principle.

Application Field

The 3120-F311-P7T1-W14FR3-15A circuit breaker is designed to be used for controlling electrical systems in low voltage industrial and commercial applications, such as those found in the transport and automotive industries. This model of circuit breaker is suitable for both single-phase and three-phase applications and is designed to be installed in enclosed spaces. It is capable of isolating the circuit to prevent electrical overloads and short circuits, thereby ensuring the safety of those in the vicinity. It is certified to meet the requirements of IEC/EN 60947-2, HD463 S2 and HD383 S2, and is highly resistant to vibration and shock.

Working Principle

When the 3120-F311-P7T1-W14FR3-15A is triggered, an internal overload protection device is activated. This device releases a mechanical or electromechanical linkage, which in turn trips the magnetic actuator that severs the connection between the contact points. This disconnects the circuit from the incoming power and the contact points remain open until reset. This reduces any potential electrical hazards and stops any further damage from occurring. The circuit breaker is able to sense electrical faults and can quickly detect and respond to current overloads and short circuits. This provides improved protection against fire hazards, electric shock, and sudden power surges.

Additional Features

The 3120-F311-P7T1-W14FR3-15A also has a number of additional features, including adjustable current and voltage settings, adjustable electrical trip delay, adjustable short circuit trip detector, and adjustable thermal trip delay. It also comes with an automatic reset feature, which helps to protect the circuit breaker in case of power failure or overload. Additionally, it has a number of visual indicators that provide feedback on the status of the circuit breaker, as well as an emergency manual reset button which can be used in the event of power failure or emergency. All of these features provide improved safety and reliability for controlling electrical systems in industrial and commercial applications.
