Eaton PL6-D25/4 Miniature Circuit Breaker, 4-Pole, D-Curve, 25A, 6kA

The Eaton PL6-D25/4 is a robust 4-pole miniature circuit breaker engineered to provide dependable protection for electrical distribution systems. Designed for demanding environments, this device effectively safeguards circuits against overloads and short circuits, ensuring the integrity of your electrical infrastructure. With its D-type tripping characteristic, it is specifically optimized to handle high inrush currents, making it a reliable choice for professional electrical installations.

Advantages

This circuit breaker offers exceptional reliability and performance in industrial and commercial settings. Its 4-pole configuration allows for comprehensive control over three-phase systems with a neutral conductor. The D-curve tripping characteristic provides a higher tolerance for temporary current spikes, preventing nuisance tripping during the startup of inductive loads such as motors or transformers. The high-quality construction ensures long-term operational stability and safety in various electrical distribution applications.

Suitable for

• Industrial machinery and motor control centers
• Commercial electrical distribution boards
• Systems with high inrush current requirements
• Three-phase AC electrical installations

When it may not be suitable

This device is not intended for residential applications where standard B or C curve breakers are typically required for lighting and general-purpose outlets. It may also be unsuitable for circuits that do not experience high inrush currents, as the D-curve characteristic is specifically tuned for inductive loads.

Key specifications

• Number of poles: 4
• Rated current: 25A
• Tripping characteristic: D-curve
• Breaking capacity: 6kA
• System type: AC

How to use

The Eaton PL6-D25/4 should be installed by a qualified electrician into a standard DIN-rail distribution board. Ensure that the supply voltage and load requirements are compatible with the device specifications before installation. The breaker is mounted by snapping it onto the rail and connecting the input and output cables to the corresponding terminals, ensuring all connections are tightened to the manufacturer's torque specifications.

What to consider before purchase

• Verify that the 25A rating matches the load requirements of your specific circuit.
• Ensure the D-curve characteristic is appropriate for the equipment being protected.
• Confirm that the 4-pole configuration is compatible with your electrical distribution system layout.

Usage recommendations: Regularly inspect the circuit breaker for signs of wear or thermal damage. Test the device periodically to ensure it remains operational and capable of tripping under fault conditions. Always adhere to local electrical codes and safety regulations during installation and maintenance.
