EATON FAZ B2/3 Miniature Circuit Breaker, 3-Pole, B-Characteristic, 2A, 15kA

The EATON FAZ B2/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in demanding environments. With a B-characteristic curve and a 2A rated current, this device is specifically designed to detect and interrupt overloads and short circuits effectively. Its high breaking capacity of 15kA ensures reliable performance in AC systems, making it a dependable component for maintaining electrical safety and system integrity.

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 curve provides a balanced response time, making it suitable for circuits with low inrush currents. Its 3-pole configuration allows for simultaneous disconnection of all phases, ensuring comprehensive protection for three-phase electrical installations. The compact design facilitates easy installation in standard distribution boards, while the high-quality construction from EATON guarantees long-term operational reliability and durability.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Protection of control circuits
• Three-phase AC power installations

This circuit breaker may not be suitable for applications requiring a different tripping characteristic, such as C or D curves, which are better suited for high inrush current loads like large motors or transformers. It is also not intended for DC circuits unless specifically rated for such use, and it should not be used in environments exceeding its specified thermal or electrical operating limits.

Key specifications

• Number of poles: 3
• Rated current: 2A
• Tripping characteristic: B
• Breaking capacity: 15kA
• System compatibility: AC

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for mounting on a standard DIN rail. Ensure that the supply voltage and frequency match the device specifications before connection. Securely tighten all terminal screws to the recommended torque to prevent overheating and ensure a reliable electrical connection.

What to consider before purchase

• Verify that the 2A rating matches the load requirements of your circuit
• Ensure the B-characteristic is appropriate for your specific equipment
• Confirm that your installation requires a 3-pole configuration
• Check that the 15kA breaking capacity meets the short-circuit current requirements of your electrical system

For optimal performance and safety, regularly inspect the circuit breaker for signs of wear or damage and ensure that the electrical load does not exceed the rated current of the device.
