Doktorvolt DV-3165 Miniature Circuit Breaker 1P B 16A 10kA AC

The Doktorvolt DV-3165 is a high-quality single-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is specifically designed to detect and interrupt overcurrent conditions, including overloads and short circuits, thereby safeguarding your electrical infrastructure and connected appliances from potential damage. With its precise B-type tripping characteristic and a 10kA breaking capacity, it offers a reliable solution for maintaining electrical safety and operational stability in AC power systems.

Advantages

The primary benefit of this circuit breaker is its high breaking capacity of 10kA, which ensures that it can safely handle significant fault currents, providing a higher level of protection than standard breakers. The B-type tripping characteristic makes it particularly effective for circuits with low surge currents, such as lighting and general-purpose power outlets. Its compact single-pole design allows for efficient space utilization within distribution boards, while the durable construction ensures long-term reliability and consistent performance under normal operating conditions.

Suitable for

• Residential lighting circuits
• General-purpose power outlets in homes
• Small commercial electrical installations
• Protection of resistive loads

This circuit breaker may not be suitable for circuits with high inrush currents, such as those powering large electric motors, transformers, or heavy-duty industrial machinery, where a C or D-type tripping characteristic would be required to prevent nuisance tripping. It is also not intended for use in DC electrical systems, as it is specifically designed for AC applications.

Key specifications

• Number of poles: 1
• Rated current: 16A
• Tripping characteristic: B
• Breaking capacity: 10kA
• System type: AC

The installation of this circuit breaker should be performed by a qualified electrician in accordance with local electrical regulations. 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. Once mounted, connect the incoming power line to the top terminal and the outgoing load line to the bottom terminal, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 16A rated current matches the requirements of your circuit load.
• Ensure the B-type characteristic is appropriate for the equipment being protected.
• Confirm that your distribution board has sufficient space for a single-pole module.
• Check that the system voltage and frequency are compatible with AC standards.

For optimal safety and performance, regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to test the mechanical operation of the switch periodically to ensure it remains functional. Never attempt to bypass or modify the internal mechanism of the device.
