Overcurrent circuit breaker series 15kA 1-pole FAZ-C40/1 278565

Safety and Reliability in Your Electrical Installation

This single-pole circuit breaker from the FAZ series is a key element in protecting electrical circuits. Designed by Eaton, it provides effective protection against overloads and short circuits, guaranteeing user safety and minimizing the risk of failure. A rated breaking capacity of 15 kA (at 400V AC) makes it an ideal choice for both domestic and industrial installations.

Characteristics and Application

The FAZ-C40/1 circuit breaker features a C characteristic, meaning it allows for short-term overloads, such as those occurring during the starting of motors or devices with heating elements. This reduces the number of unnecessary trips, ensuring continuity of power. A rated current of 40A makes it a suitable solution for circuits with medium power consumption. Mounting on a TH35 rail allows for easy and quick installation in a distribution board.

• Overload Protection: Protects the circuit from damage caused by excessive load.
• Short-Circuit Protection: Immediately interrupts the circuit in the event of a short circuit, preventing fires and equipment damage.
• C Characteristic: Ideal for circuits with devices with high inrush current – motors, transformers, heaters.
• Breaking Capacity 15kA: Ensures safe disconnection in the event of serious disturbances in the network.
• TH35 Rail Mounting: Enables quick and easy installation in standard distribution boards.

Construction and Technical Parameters

The FAZ-C40/1 circuit breaker is made of high-quality materials, guaranteeing its durability and reliability. The IP20 degree of protection provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. The ability to connect wires with a cross-section from 1 to 25 mm² (solid or stranded) provides flexibility in choosing the appropriate cables. Rated voltage 230V AC and insulation voltage 440V ensure safe operation under standard network conditions. Energy limitation class 3 confirms its effectiveness in suppressing overvoltages. The rated short-circuit breaking capacity Icn is 10kA at 230V and 400V according to EN 60898 and Icu is 15kA at 230V and 400V according to IEC 60947-2. The ambient operating temperature is in the range of -25°C to +75°C, allowing it to be used in a wide range of environmental conditions.
