## Long description

The Doktorvolt DV-3912 is a high-performance 3-pole miniature circuit breaker (MCB) engineered to provide robust protection for electrical circuits. Designed to handle a rated current of 32A with a substantial breaking capacity of 10kA, this device effectively safeguards electrical installations against overloads and short circuits. Its C-type tripping characteristic makes it a versatile solution for both residential and industrial environments, ensuring reliable power distribution and enhanced safety for connected equipment.
Advantages
This circuit breaker stands out due to its VDE certification, which guarantees adherence to rigorous safety and quality standards. The 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive protection for three-phase electrical systems. Its durable construction and 10kA breaking capacity ensure that it can handle significant fault currents, minimizing the risk of damage to electrical infrastructure and improving overall system reliability.
Suitable for
Three-phase electrical installations in residential buildings
Industrial machinery and equipment power supply lines
Commercial electrical distribution boards
Protection of motors and lighting circuits
When it may not be suitable
This device is specifically designed for 3-phase systems and is not appropriate for single-phase household circuits. Additionally, it should not be used in environments where the required rated current significantly deviates from 32A or where specific tripping curves other than C-type are mandated by local electrical regulations.
Key specifications
Number of poles: 3
Rated current: 32A
Tripping characteristic: C-curve
Breaking capacity: 10kA
Certification: VDE
How to use
The Doktorvolt DV-3912 should be installed by a qualified electrician into a standard DIN rail distribution board. Ensure that the power supply is completely disconnected before beginning the installation. Secure the device firmly onto the rail and connect the incoming and outgoing phase conductors to the appropriate terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, verify the circuit integrity before restoring power.
What to consider before purchase
Verify that the 32A current rating matches your circuit requirements
Ensure the installation space accommodates a 3-pole modular device
Confirm that the C-curve characteristic is appropriate for your specific load type
Check compatibility with existing DIN rail mounting systems
Usage recommendations
Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform a functional test periodically to ensure the tripping mechanism remains operational. If the breaker trips, investigate the cause of the overload or short circuit before attempting to reset the device.
