The Hager CDA425J 25A 30mA A 6kA four-pole 25A 6kA Type A differential circuit breaker is an electrical safety device that should be included in every household and industrial facility. Its function is to disconnect the circuit upon detecting that the outgoing current does not match the incoming current. The 25A 6KA Type A differential circuit breaker provides the best protection against electric shocks caused by direct and indirect contact. It also limits the effects of damage to electrical equipment and prevents fires. The device exhibits medium to high sensitivity and has a rated frequency of 50 Hz. The circuit breaker has a visual indicator, and a wide range of accessories facilitates installation. The device can be installed using a DIN rail, allowing for quick installation in any location. The differential circuit breaker has a degree of protection IP20 and ensures safety in accordance with the PN-EN 61008-1: 6KA standard. Technical data: . Design.

It is used in circuits with many switching power supplies, such as computers, modern AV equipment, and the like. It is not true that an AC differential switch loaded with pulsed currents will not operate or respond to leakage. It will operate as it should, but the problem is that with pulsed currents, it can cause false alarms and trip without cause. A type A differential switch is resistant to this. Hager, founded in 1955 in Germany, has become a leading supplier of electrical products for industry, residential, and commercial construction. Its product range includes power distribution, electrical installation equipment, building automation, and cable management systems.
