Eaton PL6-D20/2 Miniature Circuit Breaker, 2-Pole, D-Curve, 20A, 6kA

The Eaton PL6-D20/2 is a robust 2-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in demanding environments. With a rated current of 20A and a 6kA breaking capacity, this device is specifically designed to handle the electrical stresses associated with high inrush currents, ensuring the integrity and safety of your AC electrical distribution system.

Advantages

This circuit breaker offers superior reliability through its D-curve tripping characteristic, which allows for temporary high current surges without nuisance tripping. Its 2-pole configuration enables the simultaneous disconnection of both phase and neutral conductors, providing enhanced safety during maintenance or fault conditions. The compact design facilitates easy installation in standard distribution boards, while the high-quality construction ensures long-term operational stability in both commercial and industrial settings.

Suitable for

• Industrial machinery with high starting currents
• Commercial lighting systems with large inductive loads
• Motor control circuits
• Distribution boards requiring reliable short-circuit protection

This device may not be suitable for residential applications where standard B or C curve breakers are typically required to protect sensitive household electronics. Using a D-curve breaker in circuits with low inrush currents may result in delayed protection during a fault, as the trip threshold is set higher to accommodate specific industrial loads.

Key specifications

• Number of poles: 2
• Rated current: 20A
• Tripping characteristic: D-curve
• Breaking capacity: 6kA
• System 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. Ensure that the supply voltage and frequency match the specifications of the circuit breaker before connection. Securely tighten all terminal screws to the recommended torque to prevent overheating and ensure optimal electrical contact.

What to consider before purchase

• Verify that the D-curve characteristic is appropriate for your specific load type
• Ensure the 20A rating matches the requirements of your circuit wiring
• Confirm compatibility with your existing DIN rail distribution board
• Check that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point

Usage recommendations

Regularly inspect the circuit breaker for signs of thermal damage or loose connections. It is recommended to perform a functional test of the tripping mechanism periodically to ensure the device remains in good working order.
