Eaton PL6-B6/4 Miniature Circuit Breaker, 4-Pole, B-Curve, 6A, 6kA

The Eaton PL6-B6/4 is a professional-grade 4-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. This device is designed to detect and interrupt overloads and short circuits in AC power systems, ensuring the safety of connected equipment and wiring. With its precise B-curve tripping characteristic and a 6A rated current, it offers reliable performance for various electrical distribution applications.

Advantages

This circuit breaker stands out due to its high-quality construction and adherence to international safety standards. The 4-pole configuration allows for the simultaneous disconnection of all phases and the neutral conductor, providing comprehensive isolation. Its 6kA breaking capacity ensures that the device can safely handle significant fault currents, while the B-curve characteristic makes it particularly effective for protecting circuits with low inrush currents, such as lighting and general-purpose outlets.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• General-purpose power outlets
• Protection of sensitive electronic equipment

This circuit breaker may not be suitable for circuits with high inrush currents, such as those powering large electric motors or heavy-duty transformers, where a C-curve 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: 6A
• Tripping characteristic: B-curve
• Breaking capacity: 6kA
• System compatibility: AC power systems

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting on a standard DIN rail within a distribution enclosure. Ensure that the supply voltage matches the device specifications and that all terminal connections are tightened to the manufacturer's recommended torque settings to prevent overheating.

What to consider before purchase

• Verify the total load of the circuit to ensure the 6A rating is sufficient.
• Check the compatibility with your existing distribution board and DIN rail system.
• Confirm that the B-curve characteristic matches the requirements of your connected loads.

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