Overcurrent circuit breaker, 6kA, B characteristic, 3-pole, 6A MBN306E

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole circuit breaker from Hager, with a rated current of 6A and B characteristic, is a key element ensuring safety in every electrical installation. It provides effective protection against the effects of overloads and short circuits, protecting both wires and connected devices. Its compact dimensions – 3 module width – make it easy to install in distribution boards.

Characteristics and application

The circuit breaker with B characteristic is characterized by a delayed response time, making it an ideal solution for protecting circuits with receivers with high inrush currents, such as electric motors or devices with heating elements. This avoids unnecessary tripping of the circuit breaker when starting such devices. The rated short-circuit breaking capacity Icn is 6 kA (according to EN 60898), and Icu at 400V is 10 kA (according to IEC 60947-2), which guarantees high effectiveness in emergency situations.

Construction and installation

The circuit breaker has been designed with easy installation and convenience in mind. The possibility of flush mounting and universal screw terminals (accepting solid wires with a cross-section of 1-35 mm² and stranded wires 1-25 mm²) allow for flexible adaptation to various installation conditions. The degree of protection IP20 provides basic protection against touch and contamination. Additionally, the circuit breaker has double mounting clips allowing for removal without the need to unscrew neighboring devices (in the 10 kA version). It is also worth mentioning the innovative vertical comb busbars from Hager, which facilitate connections between devices in the distribution board.

• Overload and short-circuit protection: Protects the circuit from damage caused by excessive current.
• B characteristic: Ideal for protecting receivers with high inrush currents.
• Short-circuit breaking capacity: 6 kA (EN 60898) / 10 kA (IEC 60947-2) – high effectiveness in emergency situations.
• Flush mounting: Allows for aesthetic and discreet placement of the circuit breaker.
• Universal terminals: Accept different wire cross-sections, providing installation flexibility.
• 3 module width: Compact dimensions make it easy to install in tight distribution boards.
• Operating temperature range: -25°C to +70°C - possibility of use in difficult environmental conditions.
• Compliance with standards: Meets the requirements of IEC and EN standards, guaranteeing safety and reliability.

MBN306E circuit breaker is a solid and reliable solution for professionals and end-users looking for safe and effective protection of electrical installations.
