A circuit breaker is a device that protects an electrical circuit in the event of an overload or short circuit. In the event of an overload or short circuit, the circuit breaker disconnects the circuit, preventing further damage to the components of the circuit or other connected systems. The 3500-K20-4A is a type of circuit breaker designed to protect medium and high voltage electrical circuits.

The 3500-K20-4A is a single-pole, double-break circuit breaker designed for mounting in switchboards. It is rated up to 20 kV and 2000 A, with a maximum continuous current of 1500A for applications such as transformers, regulators, lines, motors, and other high and medium voltage applications. The device is composed of a handle mechanism and two contact arms.

The handle mechanism connects the two contact arms and is used to open and close the circuit breaker. The two contact arms are made from an arc-resistant material that prevents arc formation during the opening and closing of the circuit breaker. The contact arms contact the downstream circuit in order to disconnect the circuit. The contact arms also disconnect the circuit if an overload or short circuit is detected.

When an overload or short circuit occurs, the 3500-K20-4A circuit breaker detects the fault and trips the handle mechanism in order to disconnect the downstream circuit. The handle mechanism then raises the contact arms away from the downstream circuit, breaking the circuit and preventing further damage. The contact arms are then held in the open position, allowing the upstream circuit to cool down and allowing the fault to be repaired.

The 3500-K20-4A circuit breaker is designed to protect medium and high voltage electrical circuits. It is a single-pole, double-break device rated up to 20 kV and 2000 A. It is composed of a handle mechanism and two contact arms that open and close the circuit breaker. The contact arms disconnect the downstream circuit if an overload or short circuit is detected, preventing damage to components or other connected systems. The 3500-K20-4A is a reliable and efficient device for protecting medium and high voltage electrical circuits.
