Release mode and accessory code
Attachment name / model meaning
DZ20L series of leakage circuit breakers for AC 50HZ, rated voltage 380V, rated current up to 630A circuit as a personal contact with electric protection, can also be used to prevent damage due to equipment insulation, resulting in ground fault current caused by fire hazards, and can Used to protect the line overload and short circuit, can also be used as a frequent conversion of the line.

This series of leakage circuit breaker current operated electronic leakage circuit breakers, mainly by the zero sequence current transformer, electronic components board, leakage release and with overload and short circuit protection circuit breaker. All parts are installed in a plastic housing.

When the protected circuit in the leakage or personal shock, as long as the leakage current l △ n reaches the action value, zero sequence current transformer secondary winding output a signal, amplified by the electronic components board, and trigger the SCR drive release Action, so that the circuit breaker disconnected, thus cutting off the power to play a role in leakage and electric shock protection.
Specific product models are as follows:
DZ20LE-100/4300
DZ20LE-160/4300
DZ20LE-250/4300
DZ20LE-400/4300
DZ20LE-630/4300

DZ20L-250/4300 is my company's latest research and development with a power supply instructions and leakage adjustable adjustable new circuit breaker, the circuit breaker than the traditional leakage circuit breaker has a more humane design, the market ordinary DZ20L leakage circuit breaker Do not have the mA adjustable and power indicator function, which greatly protects the safety of the operator's life.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~
DZ20L leakage circuit breaker scope, model meaning, the main technical parameters, dimensions and installation dimensions see below:
  
DZ20L series leakage breaker is suitable for AC 50HZ, rated voltage 380V, rated current up to 630A circuit as indirect personal electric shock protection, can also be used to prevent the fire hazard caused by the damage of equipment insulation, ground fault current, andused to overload and short circuit protection circuit, and can also be used as line not frequent conversion purposes.
