Characteristics:

• A/AC type residual current circuit breaker: (colloquially differential, circuit breaker, residual current fuse (English acronyms RCD are in use) is an electrical protective device that disconnects a circuit when it detects that the electrical current flowing out of it is not equal to the incoming current.
• It is used to protect people against electric shock from direct and indirect contact, and it also limits the effects of damage to equipment and other unwanted events, including - but not limited to - the possibility of fire.
• A/AC type residual current circuit breakers are used in electrical circuits supplied with 50/60 Hz current with a rated voltage of 230 V for two-pole circuit breakers and 400 V for four-pole circuit breakers and a rated current of 25 A to 63 A.
• The circuit breaker provides safe and easy mounting on a TH35 rail with plastic clips.
• The SR6HM type A/AC line residual current circuit breakers are manufactured in accordance with IEC/EN 61008-1. To improve operational safety, they are equipped with an easy-to-read trip indicator.
• The type A/AC line residual current circuit breakers are equipped with a TEST button for checking the internal operation of the device - a test should be performed every 30 days.
