Eaton FAZ C20/2-DC Miniature Circuit Breaker, 2-Pole, 20A, 15kA, DC

The Eaton FAZ C20/2-DC is a robust 2-pole miniature circuit breaker specifically engineered for direct current (DC) electrical systems. This high-performance device is designed to provide reliable protection for industrial and commercial circuits by effectively detecting and interrupting overloads and short circuits. With a rated current of 20A and a high breaking capacity of 15kA, it ensures the safety and integrity of electrical installations operating under demanding DC conditions.

Advantages

This circuit breaker offers exceptional reliability and precision in DC power distribution. Its specialized design for direct current ensures that the arc extinction process is handled safely, preventing damage to connected equipment. The compact 2-pole configuration allows for efficient space utilization in distribution boards while maintaining high operational standards. Furthermore, the device is built to withstand rigorous industrial environments, providing long-term durability and consistent performance for critical electrical infrastructure.

Suitable for

• Industrial DC power distribution systems
• Photovoltaic (PV) installations
• Battery storage and backup power systems
• DC motor control circuits
• Commercial electrical panels requiring DC protection

When it may not be suitable

This device is specifically calibrated for direct current (DC) applications and should not be used in standard alternating current (AC) household circuits, as its arc quenching mechanism is not designed for AC waveforms. It is also not intended for use in environments exceeding its specified voltage or temperature ratings.

Key specifications

• Number of poles: 2
• Rated current: 20A
• Breaking capacity: 15kA
• Application type: Direct Current (DC)
• Tripping characteristic: C-curve

How to use

The Eaton FAZ C20/2-DC 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 correctly sized for a 20A load and that all terminal connections are tightened to the manufacturer's specified torque to prevent overheating. Once mounted, the device can be manually switched on or off using the front-facing toggle.

What to consider before purchase

• Verify that your system voltage is compatible with the DC specifications of this breaker.
• Ensure the 20A rating matches the requirements of your circuit load.
• Confirm that the C-curve tripping characteristic is appropriate for your specific equipment.
• Check the available space in your distribution board for a 2-pole module.

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 operational. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
