EATON PL6-C63/3 Miniature Circuit Breaker, 3-Pole, C-Characteristic, 63A, 6kA

The EATON PL6-C63/3 is a robust 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and industrial environments. This device is designed to monitor current flow and automatically disconnect the power supply in the event of an overload or short circuit, thereby preventing damage to wiring and connected equipment. With its reliable switching mechanism and high-quality construction, it serves as a critical component for maintaining safety and operational stability in AC power distribution systems.

Advantages

This circuit breaker offers exceptional reliability due to its high-quality manufacturing standards, ensuring consistent performance over long periods of operation. The C-characteristic makes it versatile for various applications, as it is specifically designed to handle moderate inrush currents without nuisance tripping. Its 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive protection for three-phase electrical systems. The compact design facilitates easy installation in standard distribution boards, while the 6kA breaking capacity ensures that the device can safely interrupt fault currents, protecting the integrity of the entire electrical installation.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Industrial machinery and equipment circuits
• Three-phase motor protection
• General lighting and power distribution networks

When it may not be suitable

This device is not intended for use in DC electrical systems, as it is specifically designed for AC power distribution. Additionally, it may not be suitable for circuits with extremely high inrush currents, such as large transformers or specific industrial motors, where a D-characteristic breaker might be required to prevent false tripping.

Key specifications

• Number of poles: 3
• Rated current: 63A
• Tripping characteristic: C
• Breaking capacity: 6kA
• Voltage type: AC

How to use

The EATON PL6-C63/3 should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting onto a standard DIN rail within an electrical distribution enclosure. Ensure that the supply cables are securely connected to the input terminals and that the load cables are connected to the output terminals, maintaining proper torque settings as specified by the manufacturer. Once installed, the toggle switch can be used to manually turn the circuit on or off as needed.

What to consider before purchase

• Verify that the 63A rated current matches the requirements of your specific circuit load.
• Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that your system requires a 3-pole device for three-phase power distribution.
• Check the available space in your distribution board for a 3-module wide device.

Usage recommendations: Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform a functional test of the switching mechanism periodically to ensure the device remains in optimal working condition.
