Eaton FAZ-C4/1 Miniature Circuit Breaker, 1-Pole, Type C, 4A, 15kA

The Eaton FAZ-C4/1 is a high-performance 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. With a rated current of 4A and a C-type tripping characteristic, this device is specifically designed to manage moderate inrush currents while ensuring rapid disconnection during overloads or short circuits. Its high breaking capacity of 15kA makes it a reliable component for maintaining the integrity of AC electrical systems in both commercial and industrial settings.

Advantages

This circuit breaker stands out due to its exceptional build quality and high breaking capacity, which ensures safety even in systems with significant fault current potential. The C-type characteristic provides a balanced response, allowing for the startup of inductive loads without nuisance tripping, while still offering precise protection against electrical faults. Its compact 1-pole design facilitates efficient use of space within distribution boards, and the Eaton brand reputation ensures long-term reliability and compliance with international safety standards.

Suitable for

• Industrial control panels and automation systems
• Commercial building electrical distribution
• Protection of lighting circuits with inductive components
• Small motor control applications
• General AC power distribution circuits

When it may not be suitable

This device is not intended for use in DC electrical systems, as it is specifically rated for AC applications. Furthermore, it may not be appropriate for circuits requiring a different tripping characteristic, such as B-type for sensitive electronic equipment or D-type for high-inrush motors.

Key specifications

• Number of poles: 1
• Rated current: 4A
• Tripping characteristic: C
• Breaking capacity: 15kA
• System type: AC

How to use

The Eaton FAZ-C4/1 is designed for mounting onto a standard DIN rail within an electrical enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. The device features clear terminal connections for secure wiring. Once mounted, ensure that the supply cables are properly tightened to the specified torque to prevent overheating. The toggle switch on the front allows for manual switching and indicates the current status of the circuit.

What to consider before purchase

• Verify that the 4A rating matches the load requirements of your specific circuit
• Ensure the 15kA breaking capacity is sufficient for the prospective short-circuit current at the installation point
• Confirm that the C-type tripping curve is compatible with the connected equipment
• Check available space in your distribution board for a 1-pole module

Usage recommendations

Regularly inspect the circuit breaker for signs of thermal damage or loose connections. It is recommended to perform periodic testing of the switching mechanism to ensure continued operational readiness.
