The DZ47-63 Miniature Circuit Breaker (MCB) is a dependable electrical protection device for low-voltage systems. It features a rated current range of 1A to 63A and a maximum breaking capacity of 4.5kA.
This circuit breaker effectively protects against overloads and short circuits. It is suitable for use in homes, offices, and small industrial settings.
With its compact design, the DZ47-63 is easy to install in distribution panels. It quickly disconnects power during faults to safeguard both electrical equipment and personnel.
Overall, the DZ47-63 provides reliable protection for your electrical systems, ensuring safety and peace of mind.
1. The Miniature Circuit Breaker (MCB) is made for people without technical training to use safely, and it doesn’t need maintenance.
2. In the situations mentioned, an MCB with an “ON-OFF” indicator can be used for isolation.
3. It’s recommended to install protective devices like surge protectors or surge arresters before the MCB to prevent damage from surge voltages or currents that may occur at the power input.
4. If the correct tripping curve is chosen and the MCB is properly installed, it will trip and turn off the circuit in case of a fault, providing protection from electric shock.
