Eaton PL6-C40/3 Miniature Circuit Breaker, 3-Pole, 40A, C-Curve, 6kA

The Eaton PL6-C40/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for integration into residential and commercial distribution boards, this device effectively monitors current flow to prevent damage from overloads and short circuits in AC electrical installations. Its reliable construction ensures consistent performance and safety for various electrical systems.

Advantages

This circuit breaker offers high operational reliability and durability, making it a dependable choice for modern electrical infrastructure. The C-curve tripping characteristic provides a balanced response to current surges, ensuring that the device reacts appropriately to fault conditions while maintaining stability during normal operation. Its compact 3-pole design allows for efficient space utilization within standard electrical enclosures, simplifying installation and maintenance processes.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Protection of lighting and power circuits
• General AC electrical installations

When it may not be suitable

This device is not intended for use in DC electrical systems or high-voltage industrial applications exceeding its rated specifications. It should not be installed in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.

Key specifications

• Rated current: 40A
• Number of poles: 3
• Tripping characteristic: C-curve
• Breaking capacity: 6kA
• Voltage type: AC

How to use

The Eaton PL6-C40/3 should be installed by a qualified electrician onto a standard DIN rail within a distribution board. Ensure that the supply cables are properly sized for a 40A load and securely fastened to the terminals. Once installed, the device can be manually switched on or off using the front-facing toggle. In the event of a fault, the breaker will trip automatically to disconnect the circuit; after identifying and resolving the cause of the fault, the switch can be reset to restore power.

What to consider before purchase

• Verify that the 40A rating matches your circuit requirements
• Ensure compatibility with existing DIN rail mounting systems
• Confirm the 6kA breaking capacity is sufficient for your installation's prospective short-circuit current
• Check that the 3-pole configuration is appropriate for your specific wiring setup

Usage recommendations

Always ensure the power supply is disconnected before attempting any installation or maintenance work on the distribution board. Regularly inspect the device for signs of wear or damage to maintain optimal safety standards.
