Doktorvolt DV-3158 Miniature Circuit Breaker 1P 10A 10kA B-Curve

The Doktorvolt DV-3158 is a high-quality 1-pole miniature circuit breaker (MCB) engineered to provide robust electrical protection for residential and commercial installations. This device is specifically designed to monitor electrical circuits and automatically disconnect power in the event of an overload or short circuit, thereby preventing damage to wiring and connected appliances. With its VDE certification, the unit meets stringent safety standards, ensuring consistent performance and reliability in diverse electrical environments.

Advantages

The primary advantage of this circuit breaker lies in its high breaking capacity of 10kA, which allows it to handle significant fault currents safely. The B-type tripping characteristic makes it particularly effective for protecting circuits with low inrush currents, such as lighting systems and general-purpose outlets. Its compact 1-pole design facilitates easy installation in standard distribution boards, while the durable construction ensures a long service life even under continuous operational 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, heavy-duty compressors, or large transformer banks, where a C-curve or D-curve breaker would be required to prevent nuisance tripping.

Key specifications

• Number of poles: 1
• Rated current: 10A
• Breaking capacity: 10kA
• Tripping characteristic: B-curve
• Certification: VDE

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed to be mounted onto a standard DIN rail within an electrical distribution board. Ensure that the supply power is disconnected before beginning the installation process. Once mounted, connect the incoming line to the top terminal and the outgoing load wire 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 10A rating matches the requirements of your specific circuit load.
• Ensure the B-curve characteristic is appropriate for the equipment connected to the circuit.
• Check that your distribution board has sufficient space for a 1-pole module.

Usage recommendations: 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. Do not exceed the rated current capacity to avoid unnecessary tripping or potential damage to the device.
