Circuit breaker 6kA HN-B63/3 194887

Reliable protection of electrical installations with Eaton HN-B63/3 circuit breaker

Eaton HN-B63/3 circuit breaker is a three-pole device designed to protect electrical circuits against the effects of overloads and short circuits. It is characterized by high efficiency and reliability, making it an ideal choice for both professional installers and end-users. The breaking capacity of 6kA guarantees safe disconnection of the circuit in the event of a failure, minimizing the risk of damage and fire.

Functionality and application

This circuit breaker, with a rated current of 63A, finds wide application in electrical installations of residential, commercial and industrial buildings. Thanks to its B tripping characteristic, it is particularly recommended for protecting socket and lighting circuits with resistive loads. Flush mounting ensures an aesthetic appearance of the installation. Additionally, universal screw and busbar terminals facilitate the connection of wires and busbars.

Key features and benefits

• High breaking capacity (6kA): provides effective protection against serious failures in the installation.
• B characteristic: ideal for protecting circuits with resistive loads, such as heaters or light bulbs. Allows for a quick response to sudden current increases, protecting against damage.
• Mounting on DIN rail TH 35: facilitates and speeds up installation in electrical switchboards.
• Double terminals: allow flexible connection of wires or busbars, adapting to different installation needs.
• Width of 3 modules: compact size allows for efficient use of space in the switchboard.
• Rated voltage 230V / 400V: versatility of application in different electrical systems.
• Protection degree IP20: provides basic protection against accidental contact and the ingress of solid objects larger than 12.5 mm.
• Compliance with EN 60898 standards: guarantees safety and quality confirmed by certificates.

Technical parameters in practice

The HN-B63/3 circuit breaker has been designed with durability and reliability in mind. Made of high-quality materials, it is resistant to environmental conditions and provides long-term protection of the electrical installation. The rated impulse withstand voltage of 4kV demonstrates its resistance to overvoltages. A wide range of operating temperatures (-25°C to +75°C) allows it to be used in various climatic conditions. The possibility of additional equipment allows for expanding the functionality of the circuit breaker according to individual user needs. The cross-section of the connected conductor from 1mm² to 25mm² provides great flexibility in choosing conductors adapted to a specific circuit.
