Overcurrent circuit breaker 15 kA, In=20 A, characteristic D, 2-pole FAZ FAZ-D20/2 278784

Reliable protection of electrical circuits with FAZ-D20/2 circuit breaker

The FAZ-D20/2 circuit breaker from Eaton is a two-pole modular device designed to effectively protect electrical installations from the effects of overloads and short circuits. It is characterized by a high short-circuit breaking capacity of up to 15 kA, making it an ideal choice for both professional installers and end-users looking for reliable protection.

Characteristics and application

The circuit breaker with D characteristic is particularly recommended for protecting circuits powering devices with high inrush current – motors, transformers, switch-mode power supplies or HVAC systems. The D characteristic allows for momentary exceeding of the rated current without unnecessary tripping, which prevents false alarms and downtime of devices. The rated current of 20 A provides optimal protection for a wide range of applications. The device will work perfectly in photovoltaic installations, industrial automation systems and in residential and commercial buildings.

Construction and mounting

The compact design of the circuit breaker (width of 2 modules) allows for easy mounting in standard distribution boards, saving valuable space. The cross-section of the connectable single-wire or multi-wire conductor up to 25 mm² provides flexibility in the selection of power supply cables. The circuit breaker meets high safety standards (IP20) and is designed to operate at temperatures from -25°C to 75°C. The rated impulse withstand voltage Uimp is 4 kV, which further increases its resistance to interference. The energy limitation class is 3 and the surge category is III.

Worth knowing: The FAZ-D20/2 circuit breaker has a rated short-circuit breaking capacity Icn at 10 kA at 400 V and 230 V and Icu at 15 kA at 400 V and 230 V according to IEC 60947-2 and EN 60898 standards. This guarantees effective intervention in the event of a short circuit.
