Eaton FAZ C40/2-DC Miniature Circuit Breaker, 2-Pole, 40A, 15kA

The Eaton FAZ C40/2-DC is a high-performance 2-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding industrial and commercial applications. This device is specifically designed to handle direct current (DC) systems, offering a reliable solution for maintaining operational safety and preventing damage caused by overloads or short circuits. With its precise engineering, it ensures consistent performance and system stability even under significant electrical stress.

Advantages

This miniature circuit breaker stands out due to its high breaking capacity of 15kA, which allows it to safely interrupt high fault currents, thereby protecting sensitive equipment and infrastructure. The 2-pole configuration provides comprehensive disconnection of both poles, enhancing safety during maintenance or fault conditions. Its compact design facilitates easy integration into standard distribution boards, while the robust construction ensures long-term reliability and durability in various environmental conditions.

Suitable for

• Industrial automation systems
• Commercial electrical distribution panels
• Direct current power supply circuits
• Protection of electrical machinery and control equipment

When it may not be suitable

This circuit breaker is specifically optimized for DC applications and may not be suitable for standard AC residential circuits unless explicitly specified by the system design. It should not be used in environments where the operating current exceeds the 40A rating, as this will lead to nuisance tripping or potential damage to the device.

Key specifications

• Rated current: 40A
• Number of poles: 2
• Breaking capacity: 15kA
• Application: Direct Current (DC)
• Tripping characteristic: C-curve

How to use

The device is designed for mounting on a standard DIN rail within an electrical enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply cables are securely fastened to the terminals with the correct torque to prevent overheating. Once installed, the toggle switch can be used to manually open or close the circuit, while the internal mechanism will automatically trip the switch to the off position in the event of an electrical fault.

What to consider before purchase

• Verify that your system voltage is compatible with the DC specifications of this breaker.
• Ensure the 40A rating matches the load requirements of your specific circuit.
• Check the available space in your distribution board for a 2-pole module.
• Confirm that the C-curve tripping characteristic is appropriate for your connected equipment.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform periodic testing of the switching mechanism to ensure it remains functional and free from debris. Always consult the technical documentation provided by the manufacturer for specific installation guidelines and safety protocols.
