Circuit breaker 25kA, In=80A, characteristic B. 2-pole. AZ-2-B80 174499

2-Pole Overcurrent Circuit Breaker – Reliable Installation Protection

This 2-pole overcurrent circuit breaker from the AZ series is a key element ensuring safety in any electrical installation. Designed to protect circuits against overloads and short circuits, it offers high reliability and durability, confirmed by a short-circuit breaking capacity of up to 25kA. Characteristic B provides a quick response to current increase, which is particularly important in circuits with devices with high inrush current.

Features and Application

This circuit breaker is used in both domestic and industrial installations. Its compact dimensions (width of 3 modules) allow for easy mounting in electrical switchboards. The rated current of 80A makes it ideal for protecting circuits powering devices with higher power consumption. Thanks to energy limitation class 3 and surge category 3, the circuit breaker provides effective protection against the effects of overvoltage.

• High short-circuit breaking capacity: 25kA guarantees safe disconnection of the circuit in the event of a failure.

• Characteristic B: ensures a quick response to current increase, protecting devices from damage.

• Universal application: ideal for domestic and industrial installations.

• Compact dimensions: width of 3 modules facilitates mounting in tight switchboards.

• Railway approvals: confirm the high quality and reliability of the product (information from USP).

• Expandability: compatible with auxiliary accessories, allowing you to adapt the functionality to individual needs (information from ETIM parameters).

Construction and Technical Parameters

The circuit breaker is made of high-quality materials, which guarantees its durability and reliability. The IP20 degree of protection provides protection against accidental contact, and the rated voltage of 400V and the rated insulation voltage Ui of 440V make it safe to use. The rated impulse withstand voltage Uimp is 4kV, which increases resistance to transient overvoltages. The mounting is not flush-mounted and the installation depth is 75 mm. The circuit breaker has two protected poles and does not disconnect the N pole simultaneously. The pollution degree is 2.
