Circuit breaker 6kA HN-B16/3 194881

Overcurrent circuit breaker for protecting electrical installations

This three-pole circuit breaker from Eaton, model HN-B16/3, is a reliable device designed to protect electrical installations from the effects of overloads and short circuits. The breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a failure, minimizing the risk of damage and fire. Characteristic B provides a quick response to sudden current increases, which is particularly important in circuits powering devices with high starting current.

Functionality and application

The HN-B16/3 circuit breaker is widely used in both domestic, commercial and industrial installations. It is ideal for protecting socket circuits, lighting circuits and RTV and household appliances. The possibility of mounting on a DIN TH 35 rail makes it easy to integrate with the existing electrical infrastructure. Dual terminals – screw-type and busbar – provide flexible connection of wires or busbars.

Key features and benefits

• High breaking capacity: 6kA provides effective protection against serious failures.
• Characteristic B: Fast response to short-term overloads, ideal for resistive loads and some electronic devices.
• Universal mounting: Possibility of installation on a DIN TH 35 rail facilitates integration with the existing installation.
• Flexible wire connection: Dual terminals (screw-type and busbar) increase mounting convenience.
• Wide operating temperature range: From -25°C to 75°C allows use in various environmental conditions.
• Compliance with standards: Meets safety and quality requirements confirmed by a reputable manufacturer – Eaton Electric.
• Wire cross-section: Accepts solid and stranded wires with a cross-section from 1 mm² to 25 mm².
• Rated voltage: Suitable for operation with 230V AC and 400V AC.

Technical parameters in practice

The HN-B16/3 circuit breaker is characterized by a rated current of 16A, which means it is designed to protect circuits with moderate power consumption. Energy limitation class 3 and surge category 3 provide additional protection against disturbances in the electrical network. The IP20 degree of protection protects against accidental contact, but does not provide resistance to water or dust – therefore, the circuit breaker should be mounted in a dry and well-ventilated place. The rated impulse withstand voltage Uimp is as high as 4 kV, which indicates high resistance to sudden voltage surges. A width of 3 modules allows for efficient use of space in the distribution board.
