Eaton PL6-D10/3 Miniature Circuit Breaker, 3-Pole, D-Curve, 10A, 6kA

The Eaton PL6-D10/3 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This device is specifically designed to manage electrical distribution systems by effectively detecting and interrupting overloads and short circuits. With its precise D-curve tripping characteristic, it is optimized to handle equipment that generates significant inrush currents during startup, ensuring stable operation without nuisance tripping.

Advantages

This circuit breaker offers exceptional reliability and safety for professional electrical installations. Its 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive protection for three-phase systems. The robust construction ensures long-term durability, while the 6kA breaking capacity provides sufficient protection against high-energy fault currents. By utilizing advanced tripping technology, the device maintains system integrity and minimizes downtime in industrial and commercial settings.

Suitable for

• Industrial machinery with high starting currents
• Commercial electrical distribution boards
• Three-phase motor protection
• Large lighting systems with high inrush loads
• Power supply units and transformers

This circuit breaker may not be suitable for residential applications where standard B or C curve breakers are typically required for general household appliances. It is also not intended for use in DC electrical systems, as it is specifically designed for AC distribution networks.

Key specifications

• Number of poles: 3
• Rated current: 10A
• Tripping characteristic: D-curve
• Breaking capacity: 6kA
• System compatibility: AC electrical distribution

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting onto a standard DIN rail within an electrical enclosure. Ensure that the supply voltage and frequency match the specifications of the breaker before connection. Once mounted, securely fasten the cables to the terminals, ensuring proper torque settings to prevent loose connections.

What to consider before purchase

• Verify that the D-curve characteristic is appropriate for your specific load type
• Ensure the 10A rated current matches your circuit requirements
• Confirm that the 6kA breaking capacity meets the prospective short-circuit current of your installation
• Check available space in your distribution board for a 3-pole device

For optimal performance and safety, regularly inspect the terminal connections for tightness and ensure the device is kept free from dust and moisture within a suitable enclosure.
