Eaton PL6-D13/3 Miniature Circuit Breaker, 3-Pole, D-Curve, 13A, 6kA

The Eaton PL6-D13/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical installations. This device is specifically designed to safeguard circuits against overloads and short circuits, ensuring the integrity of AC electrical distribution systems in demanding environments. With its D-type tripping characteristic, it is optimized to handle equipment that generates high inrush currents during startup, preventing nuisance tripping while maintaining high safety standards.

Advantages

This circuit breaker offers exceptional reliability and durability, making it a dependable choice for critical electrical infrastructure. The D-curve characteristic provides a higher tolerance for temporary current spikes, which is essential for protecting inductive loads such as motors, transformers, and large lighting arrays. Its compact 3-pole design allows for efficient space utilization in distribution boards, while the 6kA breaking capacity ensures that the device can safely interrupt fault currents, thereby protecting connected equipment and wiring from potential damage.

Suitable for

• Industrial machinery and motor control circuits
• Commercial lighting systems with high startup currents
• Transformers and inductive load protection
• AC electrical distribution panels

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 general-purpose lighting and socket outlets. Using a D-curve breaker in circuits without high inrush current characteristics may result in delayed protection during a fault condition.

Key specifications

• Number of poles: 3
• Rated current: 13A
• Tripping characteristic: D-curve
• Breaking capacity: 6kA
• System type: AC

How to use

The Eaton PL6-D13/3 should be installed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting onto a standard DIN rail within a distribution board. Ensure that the supply voltage and load requirements are compatible with the breaker's specifications before installation. Once mounted, connect the incoming supply cables to the top terminals and the outgoing load cables to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

• Verify that the D-curve characteristic is appropriate for your specific load type
• Ensure the 13A rating matches the circuit's design current
• Confirm compatibility with your existing distribution board layout
• Check that the 6kA breaking capacity meets the prospective short-circuit current of your installation

Usage recommendations

Regular inspection of the circuit breaker and periodic testing of the installation are recommended to ensure continued operational safety and performance. Do not exceed the rated current or breaking capacity of the device.
