Eaton FAZ B2/2 Miniature Circuit Breaker 2P 2A 15kA AC

The Eaton FAZ B2/2 is a high-performance 2-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and industrial environments. This device is designed to detect and interrupt overcurrent conditions, effectively preventing damage to wiring and connected equipment. With a 2A rated current and a 15kA breaking capacity, it offers a reliable solution for maintaining electrical safety in demanding distribution systems.

Advantages

This miniature circuit breaker stands out due to its high breaking capacity, which allows it to handle significant fault currents safely. The B-characteristic tripping curve is optimized for standard applications, ensuring a balanced response to overloads and short circuits. Its 2-pole configuration allows for the simultaneous disconnection of both phase and neutral conductors, enhancing safety during maintenance or fault events. The compact design facilitates easy installation in standard distribution boards, while the durable construction ensures long-term operational reliability.

Suitable for

• Residential electrical distribution boards
• Commercial lighting circuits
• Industrial control panels
• Protection of sensitive electronic equipment
• General purpose branch circuit protection

When it may not be suitable

This circuit breaker 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 with high inrush currents, such as those powering large motors or transformers, where a C or D characteristic breaker would be more suitable to prevent nuisance tripping.

Key specifications

• Number of poles: 2
• Rated current: 2A
• Breaking capacity: 15kA
• Tripping characteristic: B
• Voltage type: AC

How to use

The Eaton FAZ B2/2 should be installed by a qualified electrician in accordance with local electrical codes and regulations. It is designed for mounting on a standard DIN rail within an enclosure. Ensure that the supply power is disconnected before beginning the installation. Secure the device firmly onto the rail and connect the incoming and outgoing conductors to the appropriate terminals, ensuring that all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

• Verify that the 2A rating matches the requirements of your specific circuit load.
• Ensure the B-characteristic is appropriate for your application type.
• Confirm that the 15kA breaking capacity meets the short-circuit current rating of your electrical installation.
• 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 a functional test periodically to ensure the mechanism operates correctly. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
