Overcurrent circuit breaker, 6kA, B characteristic, 3-pole, 16A MBN316E

Three-pole overcurrent circuit breaker – reliable installation protection

This three-pole overcurrent circuit breaker from Hager, with a rated current of 16A and a short-circuit breaking capacity of 6kA, is a key element of every safe electrical installation. Designed for both home and professional use, it provides effective protection of circuits against overloads and short circuits. Characteristic B makes it ideal for circuits with devices with low inrush current, minimizing the risk of unnecessary tripping.

Key features and application

The MBN316E circuit breaker is characterized by a compact design – it occupies 3 modules on a DIN rail – which facilitates installation in distribution boards. It is intended for protecting circuits with a rated voltage of 400V and a frequency of 50/60Hz. Thanks to the rated insulation voltage Ui of 500V and energy limitation class 3, it ensures a high level of safety. The possibility of connecting wires with a cross-section from 1 to 35 mm² (solid) or from 1 to 25 mm² (stranded) provides great flexibility during installation.

• Wide range of applications: ideal for protecting lighting, sockets in residential premises, as well as circuits powering electrical appliances in commercial buildings.
• Characteristic B: ensures a quick response to overloads and short circuits, while allowing for trouble-free starting of devices with a short-term increase in current draw.
• Compact dimensions: occupies only 3 modules on a DIN rail, saving space in the distribution board.
• High quality workmanship: guarantees reliable operation and long service life.
• Compliance with standards: meets the requirements of PN-EN 60898-1, ensuring safety and compliance with regulations.

Construction and technical parameters

The MBN316E circuit breaker has been designed with easy installation and intuitive operation in mind. It has screw terminals allowing for a secure connection of wires. The housing made of high-quality plastic ensures durability and resistance to mechanical damage and external factors. Additionally, the circuit breaker has a degree of protection of IP20, which means protection against touching fingers and against the ingress of solid bodies larger than 12.5 mm. The rated short-circuit breaking capacity Icn is 6kA at 400V and Icu is 10kA at 400V according to IEC 60947-2. The ambient operating temperature is in the range of -25°C to +70°C, allowing it to be used in various environmental conditions.

The Hager MBN316E circuit breaker is a solid and reliable solution for every installer and user looking for effective protection of the electrical installation. Its versatility, ease of installation and high quality workmanship make it an ideal choice for both new installations and modernization of existing electrical systems.
