Overcurrent circuit breaker 15 kA, In=16 A, characteristic D, 2-pole FAZ FAZ-D16/2 278783

Overcurrent circuit breaker – reliable protection for electrical installations

This two-pole circuit breaker from Eaton's FAZ series, with a rated current of 16A and a D characteristic, is a key element ensuring safety in every electrical installation. The rated short-circuit breaking capacity of 15kA guarantees an effective response in emergency situations, protecting against damage and potential hazards. This circuit breaker is used in both domestic and industrial installations where high reliability and protection against overloads and short circuits are required.

Features and application

The FAZ-D16/2 circuit breaker has been designed with a wide range of applications in mind. The D characteristic means a delayed response to current increase, making it an ideal choice for circuits with devices generating high inrush currents during start-up – such as motors, pumps or compressors. This minimizes the risk of unnecessary tripping of the circuit during normal operation of these devices. Mounting on a TH35 rail allows for easy and quick installation in a distribution board. A width of 2 modules ensures compact dimensions and optimal use of space in the switchgear cabinet.

• High short-circuit breaking capacity: 15 kA at 400V and 230V provides effective protection even in difficult conditions.

• D characteristic: Delayed response to current increase, ideal for circuits with motors and other devices generating inrush currents.

• Mounting on TH35 rail: Quick and easy installation in standard distribution boards.

• Compact dimensions: 2 module width saves space in the switchgear cabinet.

• Protection class IP20: Provides protection against accidental contact.

• Wire cross-section: Possibility to connect solid and stranded wires with a cross-section from 1 to 25 mm².

• Operating temperature: A wide range of operating temperatures from -25°C to +75°C enables use in various environmental conditions.
