Doktorvolt DV-4261 RCCB Residual Current Circuit Breaker 4P 63A 30mA Type A 10kA

The Doktorvolt DV-4261 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in both residential and industrial environments. This device is designed to monitor electrical circuits and automatically disconnect power when a residual current is detected, effectively protecting users from electric shock and preventing potential fire hazards caused by insulation faults. With its robust construction and VDE certification, it serves as a reliable component in modern electrical distribution systems.

Advantages

The primary advantage of this RCCB is its Type A protection, which allows it to detect not only standard AC residual currents but also pulsating DC currents, making it suitable for modern electronic equipment that may produce complex leakage patterns. The device features a high short-circuit capacity of 10kA, ensuring it can withstand significant electrical stress during a fault event. Its 4-pole configuration provides versatility for three-phase installations, while the 30mA sensitivity threshold is calibrated to provide a high level of personal protection without causing unnecessary nuisance tripping in standard operating conditions.

Suitable for

• Residential electrical distribution boards
• Industrial machinery and equipment protection
• Commercial building electrical systems
• Installations involving electronic devices with power electronics

When it may not be suitable

This device is not intended for use in DC-only circuits or systems where the residual current characteristics exceed the capabilities of Type A protection, such as those requiring Type B devices for high-frequency or smooth DC leakage. It should not be installed in environments that exceed the specified operating temperature or humidity ranges defined by the manufacturer.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Rated residual operating current: 30mA
• Type: A
• Short-circuit capacity: 10kA
• Certification: VDE

How to use

The Doktorvolt DV-4261 must be installed by a qualified electrician in accordance with local electrical regulations and standards. It is typically mounted on a standard DIN rail within a distribution cabinet. Ensure that all electrical connections are tightened to the specified torque to prevent overheating. After installation, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.

What to consider before purchase

• Verify that the 63A rated current matches the requirements of your circuit.
• Ensure the 30mA sensitivity is appropriate for the intended application.
• Confirm that the installation environment is compatible with the device specifications.
• Check if your system requires Type A protection for specific electronic loads.

Usage recommendations: It is recommended to perform a functional test of the residual current circuit breaker using the test button at least every six months to ensure the internal mechanism remains operational and reliable over time.
