Product Overview

The Eaton FAZ-C10/3 stands as a premier solution for overcurrent and short-circuit protection in complex industrial power distribution systems. This 3-pole miniature circuit breaker features a Type C tripping characteristic, specifically engineered to handle moderate inductive loads where medium inrush currents occur, such as small motor starters and control transformer circuits. Unlike standard residential breakers, the FAZ series provides superior current-limiting performance (Class 3), significantly reducing the thermal and mechanical stress on downstream components during a fault. Its robust 10A rated capacity and high-quality switching mechanism ensure maximum uptime for critical machinery, shielding your infrastructure from catastrophic electrical failures while maintaining a compact DIN-rail footprint.

Core Technical Advantages

Precise Tripping Mechanism

The Type C release characteristic provides a magnetic trip threshold between 5 and 10 times the rated current. This precision prevents nuisance tripping during the startup phase of inductive equipment while maintaining an instantaneous response to genuine short-circuit events, safeguarding sensitive electronics and heavy-duty industrial hardware alike.

Superior Current Limitation

As a Current Limiting Class 3 device, the FAZ-C10/3 rapidly extinguishes the electrical arc during a fault. This ultra-fast disconnection minimizes the let-through energy, protecting cable insulation and ensuring the longevity of connected industrial sensors, PLC modules, and power supplies.

Modular Flexibility

The FAZ hardware platform supports extensive field-mountable accessories. Engineers can easily integrate auxiliary contacts, trip signal switches, or shunt trips to incorporate the breaker into remote monitoring and automated safety shutdown sequences within a broader SCADA or DCS architecture.

Technical Specifications

Engineering Installation Guide

Terminal Security and Torque

The FAZ-C10/3 features twin-purpose terminals that accommodate both busbars and cables. For a high-integrity connection, ensure all screw terminals are tightened to a torque of 2.4 Nm. Proper torque prevents localized overheating at the connection point, which is a common cause of premature failure in high-vibration industrial environments.

Thermal Derating Considerations

When mounting multiple breakers side-by-side in a control cabinet, engineers must account for heat dissipation. If the ambient temperature exceeds 30°C, apply a derating factor to the rated current. Ensure a minimum clearance of 10mm from non-ventilated cabinet walls to facilitate natural convection.

Busbar Integration

The design allows for the use of standard Z-GV busbars on either the top or bottom terminals. This bi-directional feed capability simplifies the wiring of multi-circuit distribution boards, reducing cable clutter and improving the overall clarity of the electrical assembly.

Engineering Advantages

The FAZ-C10/3 excels in extreme commercial and industrial environments where reliability is non-negotiable. Its high-quality contact material and arc-chute design enable consistent performance under high-duty cycles. With an overvoltage category of III and pollution degree 2 rating, this breaker maintains its dielectric strength even in atmospheres containing dust or light humidity. Furthermore, the toggle position provides a clear visual indication of the circuit status (Red/Green), allowing maintenance teams to identify tripped circuits instantly, thereby reducing MTTR (Mean Time To Repair) during facility outages.

Technical FAQs

Q1: What is the main difference between a Type B and Type C breaker for my system?

A1: Type B breakers trip between 3-5 times the rated current and are for resistive loads. The Type C (FAZ-C10/3) trips between 5-10 times the rated current, making it essential for circuits with small motors or transformers that have moderate inrush current.

Q2: Can I use this FAZ-C10/3 for DC applications?

A2: While primarily designed for AC, the FAZ series is rated for specific DC voltages (typically up to 60V per pole). For high-voltage DC circuits, we recommend utilizing the FAZ-NA or specialized DC-rated models to ensure proper arc extinction.

Q3: Does the breaker require a specific mounting orientation?

A3: The FAZ-C10/3 is designed for standard vertical or horizontal DIN-rail mounting. Its performance remains consistent regardless of orientation, provided that adequate ventilation and clearance are maintained for heat dissipation.

Q4: What is the maximum breaking capacity (Icu) of this model?

A4: The FAZ-C10/3 typically offers a breaking capacity of 10 kA according to IEC/EN 60947-2, making it suitable for industrial branch circuit protection where higher fault currents may occur.
