Overcurrent circuit breaker 25kA, In=20A, characteristic D. 2-pole. AZ-2-D20 174502

Overcurrent circuit breaker – reliable protection for electrical installations

This two-pole overcurrent circuit breaker from the AZ series is a key element ensuring safety in every 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 D makes it ideal for protecting circuits with devices generating high inrush currents, such as motors or transformers.

Design and application

The AZ-2-D20 circuit breaker is made of high-quality materials, which guarantees its durability and resistance to damage. Compact dimensions (1 module width) allow for easy installation in electrical distribution boards. The use of characteristic D means that the circuit breaker reacts with a delay to short-term current surges, which prevents unnecessary tripping during the start-up of high-power devices. This makes it a particularly useful solution in industrial installations, workshops, and in homes with a large number of energy-consuming receivers.

Key features and benefits

• High short-circuit breaking capacity (25kA): ensures effective protection of the installation even in the event of serious failures.
• Characteristic D: ideal for protecting circuits with motors, transformers and other devices generating high inrush currents. Allows to avoid unnecessary tripping during the start-up of these devices.
• Compact dimensions (1 module): facilitate installation in tight electrical distribution boards.
• Compliance with standards: ensures safety and reliable operation.
• Expandability: compatible with a wide range of auxiliary accessories, allowing it to be adapted to individual installation needs.
• Durability and railway approvals: confirm the high quality of the product and its suitability for demanding applications.
• Protection degree IP20: provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.

The circuit breaker is characterized by a rated current of 20A and a short-circuit breaking capacity of 15kA at a voltage of 400V and 230V. It has a D tripping characteristic, is two-pole and occupies a width of 1 module.

This circuit breaker is not only a protective element – it is an investment in peace of mind and the safety of your electrical installation. Both for professionals performing installations and for end users looking for a reliable solution, the AZ-2-D20 is an optimal choice.
