Eaton PL6-C40/4 Miniature Circuit Breaker, 4P, C-Curve, 40A, 6kA

The Eaton PL6-C40/4 is a professional-grade 4-pole miniature circuit breaker engineered to provide robust protection for electrical distribution systems. Designed for alternating current (AC) applications, this device effectively monitors circuits to detect and interrupt overloads and short circuits, thereby safeguarding connected equipment and wiring from potential damage. With its reliable mechanical design and high-quality construction, it serves as a critical component in maintaining electrical safety standards in both residential and industrial environments.

Advantages

This circuit breaker stands out due to its high breaking capacity of 6kA, which ensures reliable performance even under demanding electrical conditions. The C-curve tripping characteristic provides a balanced response, making it suitable for a wide range of loads including those with moderate inrush currents. Its 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral, providing comprehensive isolation for three-phase systems. The robust build quality from Eaton ensures long-term operational stability and durability in various installation settings.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Industrial machinery and control panels
• Protection of three-phase circuits with neutral

When it may not be suitable

This device is not intended for use in direct current (DC) systems and should not be installed in circuits exceeding its 40A rated current capacity. It is also not suitable for applications requiring specific tripping characteristics other than the C-curve, such as highly sensitive electronic equipment that may require a B-curve breaker.

Key specifications

• Number of poles: 4
• Rated current: 40A
• Tripping characteristic: C-curve
• Breaking capacity: 6kA
• System type: AC

How to use

The Eaton PL6-C40/4 is designed for mounting on a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Ensure that the supply power is disconnected before beginning the installation. The device features secure terminal connections that should be tightened to the manufacturer's specified torque to ensure optimal electrical contact and prevent overheating.

What to consider before purchase

• Verify that the 40A 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 the 4-pole configuration is compatible with your existing wiring layout.
• Check the available space in your distribution board to accommodate the width of a 4-pole device.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform a functional test by toggling the switch periodically to ensure the mechanism remains free and operational. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
