Doktorvolt DV-5538 Miniature Circuit Breaker 1P B 16A 6kA AC

The Doktorvolt DV-5538 is a high-quality single-pole miniature circuit breaker engineered to provide essential protection for electrical circuits in residential and commercial environments. This device is specifically designed to monitor current flow and automatically disconnect the power supply in the event of an overload or short circuit, thereby safeguarding your wiring and connected electrical appliances from potential damage.

Advantages

This circuit breaker offers robust performance and long-term reliability due to its precise manufacturing standards. The B-type tripping characteristic makes it an ideal choice for general-purpose applications where moderate inrush currents are expected. With a 6kA breaking capacity, it effectively handles fault currents, ensuring that your electrical system remains stable and secure under various operating conditions. Its compact single-pole design allows for efficient use of space within standard distribution boards.

Suitable for

• Residential lighting and power socket circuits
• Small commercial office electrical installations
• Protection of general household appliances
• Sub-distribution boards in buildings

When it may not be suitable

This device is not intended for use in DC electrical systems, as it is specifically designed for AC applications. Furthermore, it may not be suitable for circuits with high-starting-current equipment, such as large industrial motors or heavy-duty compressors, where a C or D-type tripping characteristic would be required to prevent nuisance tripping.

Key specifications

• Number of poles: 1
• Rated current: 16A
• Tripping characteristic: B
• Breaking capacity: 6kA
• System type: AC

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the power supply is completely disconnected before beginning the installation process. The device is mounted by snapping it onto the rail and securing the electrical connections firmly to the input and output terminals. Once installed, the switch can be toggled to the ON position to energize the circuit.

What to consider before purchase

• Verify that the 16A rated current matches the requirements of your specific circuit load.
• Ensure the B-type characteristic is appropriate for the devices connected to this circuit.
• Confirm that the installation environment is compatible with AC-rated protection devices.
• Check the available space in your distribution board for a single-module width device.

Usage recommendations

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform a functional test periodically to ensure the mechanism operates correctly. If the breaker trips frequently, investigate the connected load for potential faults before resetting.
