Description
The ABB FAZ-C2/1 is a high-reliability miniature circuit breaker (MCB) designed for industrial and commercial electrical distribution systems, serving as a critical component for overload and short-circuit protection in low-voltage (LV) networks. As part of ABB’s FAZ-C Series, this single-pole (1P) breaker is engineered to meet the demands of modern power distribution, offering precise tripping characteristics and rapid fault interruption. The ABB FAZ-C2/1 is rated for 2 A current and features a compact design, making it ideal for space-constrained applications such as control panels, machine tools, lighting circuits, and small-scale renewable energy systems.
Constructed with a thermomagnetic tripping mechanism, the FAZ-C2/1 combines thermal protection against overloads and magnetic protection against short circuits, ensuring reliable operation across a wide temperature range (-30°C to +70°C). Its screwless terminal design and DIN rail mounting simplify installation and maintenance, while the visible toggle switch provides clear status indication (ON/OFF/TRIPPED). Positioned as a cost-effective and space-efficient solution, the ABB FAZ-C2/1 enhances system safety by minimizing downtime and preventing damage to connected equipment, making it a trusted choice for electrical engineers and installers worldwide.

The ABB FAZ-C2/1’s C-type tripping curve is optimized for inductive loads (e.g., motors, transformers), providing delayed tripping for inrush currents while rapidly interrupting fault currents ≥5–10x the rated current. This prevents nuisance tripping during normal motor starting while ensuring fast fault clearance in case of short circuits. For example, in a commercial kitchen’s ventilation system, the breaker protects the induction motor from overloads caused by grease buildup, while instantly tripping if a faulty fan blade contacts a live wire.
At just 18 mm width, the FAZ-C2/1 saves up to 50% space compared to traditional breakers, enabling denser panel layouts in data centers or residential switchboards. The screwless spring clamp terminals accept solid or stranded wires (1–2.5 mm²) without tools, reducing installation time by 30%. The push-to-test button allows quick verification of tripping functionality during commissioning, while the UV-resistant polycarbonate housing ensures long-term durability in exposed environments.
The breaker’s low power loss (≤0.3 W at rated current) minimizes heat generation, improving energy efficiency in large-scale installations. The arc chute technology contains and extinguishes arcs within microseconds, reducing the risk of electrical fires and protecting personnel during fault events. Additionally, the phase-compatible design allows easy integration with ABB’s FAZ-C series multi-pole breakers (e.g., 2P, 3P) for three-phase systems, ensuring consistent performance across the entire distribution network.
The ABB FAZ-C2/1 is versatile across industries requiring reliable low-current protection:
- Commercial Buildings: Protects lighting circuits, CCTV systems, and small HVAC components in offices and retail spaces. For instance, in a smart building’s IoT sensor network, the breaker safeguards low-power edge devices (e.g., occupancy sensors) from voltage spikes caused by elevator motor startups.
- Industrial Automation: Used in control panels for CNC machines, robotics, and packaging lines to protect low-voltage control circuits (24 V DC). In a pharmaceutical filling line, the FAZ-C2/1 ensures uninterrupted operation of pneumatic valve controllers, preventing batch contamination from unexpected downtime.
- Renewable Energy: Ideal for solar inverter DC circuits and battery storage systems, where its wide temperature range and anti-corrosive terminals withstand outdoor conditions. In a residential solar setup, the breaker protects the DC wiring between panels and the inverter, ensuring safety during maintenance.
- Marine and Offshore: Deployed in shipboard electrical systems to protect navigation lights and communication equipment. The breaker’s vibration-resistant design (compliant with IEC 60068-2-6) makes it suitable for offshore platforms and marine vessels.
- ABB FAZ-C4/1: A 4 A variant for slightly higher-current applications, such as small pumps or industrial fans.
- ABB FAZ-C2/1-NO: A normally open (NO) version for alarm circuits, providing a dry contact for remote fault indication.
- ABB FAZ-C2/2: A 2P (two-pole) version for single-phase 230 V AC systems, offering simultaneous line and neutral protection.
- ABB SH201-C2: A similar 2 A MCB from ABB’s SH200 series, compatible with plug-in surge protective devices (SPDs).
- ABB Tmax XT1N: A molded case circuit breaker (MCCB) for higher-current applications (up to 160 A), suitable for main distribution panels paired with the FAZ-C2/1 for sub-circuits.
Pre-installation preparation: Mount the ABB FAZ-C2/1 on a DIN rail in a ventilated control panel, ensuring at least 10 mm clearance between breakers for heat dissipation. Strip wire ends to 10 mm and insert into the screwless terminals, pushing until the wire is securely clamped. Verify the supply voltage matches the breaker’s rating (230 V AC) and ensure the circuit load does not exceed 2 A.
Maintenance recommendations: Inspect the breaker’s toggle switch and terminals quarterly for signs of overheating (e.g., discoloration). Use a digital multimeter to test continuity when the breaker is in the ON position and confirm tripping functionality with a test device. In dusty environments, clean the housing with a dry cloth to prevent dust accumulation affecting heat dissipation. Replace the breaker if it trips frequently without apparent cause, as this may indicate a worn internal mechanism.
ABB stands behind the ABB FAZ-C2/1 with a 10-year warranty, reflecting confidence in its durable design and materials. ABB’s global Electrification Service Team provides technical support for installation, troubleshooting, and replacement, with online resources including datasheets, CAD models, and installation guides. The breaker undergoes rigorous testing, including 10,000 mechanical operation cycles and 1,000 fault interruption tests, to ensure compliance with IEC standards. For customers in regulated industries, ABB offers customized certification packages (e.g., marine approvals for Lloyd’s Register), ensuring the FAZ-C2/1 meets project-specific requirements. By combining precision protection, compact design, and ABB’s legendary reliability, the FAZ-C2/1 sets the standard for miniature circuit breakers in modern electrical systems.
