Eaton PL6-D16/3N Miniature Circuit Breaker 3P+N 16A D-Curve 6kA

The Eaton PL6-D16/3N is a professional-grade miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. This 3P+N device is designed to safeguard electrical installations against overloads and short circuits, ensuring operational safety and system reliability. With a rated current of 16A and a D-type tripping characteristic, it is specifically optimized for circuits with high inrush currents, such as those powering motors or large transformers.

Advantages

This circuit breaker offers exceptional reliability due to its high-quality construction and precise tripping mechanism. The D-curve characteristic allows for higher tolerance during initial power-up phases, preventing nuisance tripping in applications with inductive loads. Its modular design facilitates seamless integration into standard distribution boards, making it a versatile choice for both new installations and system upgrades. The 6kA breaking capacity ensures that the device can effectively interrupt fault currents, protecting downstream equipment from potential damage.

Suitable for

• Industrial machinery and motor control circuits
• Commercial electrical distribution systems
• Applications with high inrush current equipment
• Protection of lighting systems with large capacitive loads

When it may not be suitable

This device is not intended for residential circuits requiring standard B or C curve characteristics, as the D-curve is specifically tuned for high-surge loads. Using it in standard household lighting or general-purpose outlet circuits may result in delayed protection during a fault.

Key specifications

• Rated current: 16A
• Tripping characteristic: D-curve
• Number of poles: 3P+N
• Breaking capacity: 6kA
• Mounting type: DIN rail

How to use

The Eaton PL6-D16/3N should be installed by a qualified electrician in accordance with local electrical codes. The device is designed to be snapped onto a standard 35mm DIN rail within a distribution board. Ensure that the supply cables are securely connected to the input terminals and that the load cables are connected to the output terminals, observing the correct torque settings to prevent loose connections.

What to consider before purchase

• Verify that the D-curve characteristic matches the specific load requirements of your equipment.
• Ensure the distribution board has sufficient space for a 4-module wide device.
• 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 continued operational readiness.
