Doktorvolt 3-Phase Miniature Circuit Breaker C63 3P 400V 10kA 3-Module

The Doktorvolt 3-Phase Miniature Circuit Breaker C63 3P 400V 10kA is a high-performance protective device engineered to safeguard electrical systems against overloads and short circuits. Designed for professional electrical installations, this 3-module unit provides reliable current interruption in 400V AC networks, ensuring the integrity of connected equipment and wiring.

Advantages

This circuit breaker offers exceptional reliability due to its robust construction and VDE certification, which confirms adherence to stringent safety standards. The 10kA breaking capacity allows it to handle significant fault currents, making it suitable for demanding environments. Its 3-pole configuration ensures simultaneous disconnection of all phases, providing comprehensive protection for three-phase circuits in both residential and industrial settings.

Suitable for

• Industrial machinery and equipment power supply
• Residential three-phase electrical distribution boards
• Commercial building electrical infrastructure
• Protection of high-load electrical circuits

This device may not be suitable for single-phase household circuits or low-voltage DC applications. It is specifically calibrated for 400V AC three-phase systems and should not be used in environments where the expected fault current exceeds its 10kA rating.

Key specifications

• Rated current: 63A
• Number of poles: 3
• Voltage rating: 400V AC
• Breaking capacity: 10kA
• Mounting: 3-module DIN rail
• Certification: VDE

How to use

The circuit breaker is designed for installation on a standard DIN rail within an electrical distribution board. It should be installed by a qualified electrician in accordance with local electrical codes. Ensure that the supply voltage matches the 400V specification and that the wire gauge is appropriate for a 63A current rating. Once mounted, the device is operated via the manual toggle switch on the front panel.

What to consider before purchase

• Verify that your electrical system requires a 63A rated current
• Ensure there is sufficient space for a 3-module device in your distribution box
• Confirm that the installation environment is compatible with the device's technical ratings

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform a functional test of the switching mechanism periodically to ensure continued operational reliability.
