Eaton PL6-B13/4 Miniature Circuit Breaker, 4-Pole, B-Curve, 13A, 6kA

The Eaton PL6-B13/4 is a high-quality 4-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in various environments. With a rated current of 13A and a B-curve tripping characteristic, this device is specifically designed to detect and interrupt overcurrents caused by overloads or short circuits. Its 6kA breaking capacity ensures that it can safely handle fault currents, maintaining the integrity of your electrical infrastructure and protecting connected equipment from potential damage.

Advantages

This circuit breaker stands out due to its robust construction and reliable performance in AC power systems. The 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral conductor, providing comprehensive safety during maintenance or fault conditions. Its B-curve characteristic makes it particularly effective for protecting circuits with low inrush currents, such as lighting and general-purpose outlets, ensuring that the breaker does not trip unnecessarily while still providing rapid response to genuine electrical faults.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• General-purpose power outlets
• Protection of resistive loads

This device may not be suitable for circuits with high inrush currents, such as those powering large motors, transformers, or heavy-duty industrial machinery, where a C or D curve breaker would be more appropriate to prevent nuisance tripping. It is also not intended for use in DC power systems.

Key specifications

• Number of poles: 4
• Rated current: 13A
• Tripping characteristic: B-curve
• Breaking capacity: 6kA
• Voltage type: AC

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for mounting on a standard DIN rail within a distribution enclosure. Ensure that the supply is disconnected before beginning installation and verify that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 13A rating matches the requirements of your circuit load.
• Ensure the 4-pole configuration is compatible with your specific wiring system.
• Check that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that the B-curve is appropriate for the type of equipment being protected.

Regular inspection of the distribution board is recommended to ensure that all connections remain secure and that the circuit breaker is free from dust or debris that could impede its operation.
