Eaton PL6-C50/3 Miniature Circuit Breaker, 3-Pole, C-Characteristic, 50A, 6kA

The Eaton PL6-C50/3 is a robust 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. Designed for both residential and industrial applications, this device serves as a critical safety component by monitoring electrical flow and disconnecting the circuit in the event of an overload or short circuit. With its high-quality construction and precise engineering, it ensures the longevity of connected equipment and the overall safety of the electrical infrastructure.

Advantages

This circuit breaker offers exceptional reliability through its advanced thermal-magnetic tripping mechanism, which provides consistent performance under varying load conditions. Its 3-pole configuration makes it perfectly suited for three-phase power systems, ensuring balanced protection across all phases. The C-characteristic curve is specifically optimized for applications with moderate inrush currents, preventing nuisance tripping while maintaining a high level of sensitivity to genuine electrical faults. The compact design allows for efficient installation in standard distribution boards, saving valuable space while maintaining high operational standards.

Suitable for

• Three-phase electrical distribution systems
• Industrial machinery and motor control circuits
• Residential electrical panels requiring high-current protection
• Commercial building power distribution

This device may not be suitable for circuits requiring a different tripping characteristic, such as B-type for sensitive electronic equipment or D-type for high-inrush inductive loads. It is also not intended for use in DC circuits unless specifically rated for such applications, as this model is designed for standard AC electrical systems.

Key specifications

• Number of poles: 3
• Rated current: 50A
• Tripping characteristic: C
• Breaking capacity: 6kA
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is mounted onto a standard DIN rail within a distribution enclosure. Ensure that the supply voltage is disconnected before beginning the installation process. Secure the input and output cables firmly into the terminals, ensuring that the connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 50A rating 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 the 3-pole configuration is compatible with your three-phase power supply
• Check the available space in your distribution board for a 3-module wide device

Regular inspection of the circuit breaker is recommended to ensure that all terminal connections remain tight and free from signs of thermal stress. Periodically check the device for any physical damage or discoloration that may indicate an underlying electrical issue.
