The Doktorvolt DV-3882 is a high-performance 3-pole miniature circuit breaker (MCB) engineered to provide robust protection for electrical circuits in both residential and industrial environments. This device is designed to detect and interrupt overcurrents, effectively safeguarding wiring and connected equipment from the risks of overloads and short circuits. With a rated current of 16A and a C-type tripping characteristic, it offers a reliable balance between sensitivity and operational stability, backed by VDE certification for quality and safety.
Advantages
The primary benefit of this circuit breaker is its high breaking capacity of 10kA, which allows it to handle significant fault currents safely, providing superior protection compared to standard residential breakers. Its 3-pole configuration makes it ideal for protecting three-phase electrical systems, ensuring that all phases are disconnected simultaneously during a fault. The C-curve characteristic is specifically chosen to accommodate moderate inrush currents, making it versatile for various types of electrical loads. Furthermore, the VDE certification ensures that the device meets stringent international safety and performance standards, offering peace of mind for professional installers and homeowners alike.
Suitable for
- Three-phase electrical installations in residential buildings
- Industrial machinery and equipment power supply lines
- Commercial distribution boards
- Protection of lighting and heating circuits with moderate starting currents
This circuit breaker may not be suitable for applications requiring a different tripping characteristic, such as B-curve for highly sensitive electronic equipment or D-curve for motors with very high starting currents. It is also not intended for use in single-phase circuits where a 1-pole or 2-pole breaker would be more appropriate.
Key specifications
- Number of poles: 3
- Rated current: 16A
- Tripping characteristic: C-curve
- Breaking capacity: 10kA
- Certification: VDE
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for mounting on a standard DIN rail within a distribution board. Ensure that the supply power is disconnected before beginning the installation process. Secure the breaker firmly onto the rail and connect the input and output cables to the corresponding terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
- Verify that the 16A rating matches the requirements of your circuit load
- Ensure the 3-pole configuration is compatible with your electrical system
- Check that the C-curve characteristic is appropriate for the connected devices
- Confirm that the physical dimensions fit your existing distribution board space
For optimal performance and safety, regularly inspect the circuit breaker for signs of wear or damage and ensure that the terminal connections remain tight over time. Do not exceed the rated current capacity of the device.
