VCX PR8NM RCCB 3PH 4P AC 63A 100mA Residual Current Circuit Breaker

Characteristics:

• The PR8NM type A/AC residual current circuit breaker, commonly known as a differential, circuit breaker or residual current circuit breaker (abbreviated RCD or RCCB), is an electrical protective devicea protective device that disconnects an electrical circuit when it detects that the current flowing out of the circuit is not compatible with the incoming current.
• Its main purpose is to protect people from electric shock, both in the case of indirect and direct contact.
• In addition, it limits the effects of damage to electrical equipment and minimises the risk of fire.
• Residual current circuit breakers are used both in residential buildings and in industry.
• The PR8NM line of Type A/AC residual current circuit breakers, also known as Type A/AC circuit breakers, are used in electrical circuits supplied with a current offrequency of 50/60 Hz and rated voltage of 230 V (for two-pole circuit breakers) or 400 V (for four-pole circuit breakers) and rated current of 25 A to 63 A.
  
• They comply with the IEC/EN 61008-1 standard.
• Assembly of the circuit breakers is only possible by qualified personnel. It is recommended to disconnect the power supply before mounting.
  
• The switches can be easily mounted on a TH35 rail using plastic mounting clips.
  
• The device is equipped with an easy-to-read operation indicator to improve safety in use.
• The PR8NM type A/AC line residual current circuit breakers have a TEST button for regular verification of the correct internal operation of the device and should be activated every 30 days.
