Tax included
The HN-B20/3 miniature circuit breaker is an advanced protective device from the renowned manufacturer EATON, designed to provide the highest level of safety in modern electrical installations. It is a three-phase model with a rated current of 20A and Type B tripping characteristic, making it an ideal choice for protecting lighting circuits, control circuits, and standard power outlets in residential, office, and industrial buildings.The main task of this circuit breaker is to instantly interrupt the circuit in the event of a short circuit or overload, which effectively protects connected devices and the installation itself from permanent damage or fire risk. Thanks to a rated short-circuit breaking capacity of 6000 A, the device guarantees reliability and operational stability even under demanding conditions. The circuit breaker features a robust construction made of high-quality plastic that is resistant to high temperatures and mechanical damage.Installation of the device is extremely intuitive thanks to the standard TS-35 DIN rail mounting system, which allows for quick integration into any electrical distribution board. The circuit breaker occupies the width of three standard modules (52.5 mm). An additional advantage that increases user comfort is the built-in, clear contact position indicator, allowing for immediate verification of the device's operating status without the need for additional measuring tools. Screw terminals ensure a secure and durable connection for wires with a cross-section from 1 mm² to 25 mm², which minimizes the risk of contact loosening during operation. The ability to seal the lever provides additional protection against unauthorized access. By choosing EATON brand equipment, you are investing in proven technical solutions that meet rigorous European safety standards, ensuring trouble-free operation of the electrical network for many years.

Device type
Professional miniature circuit breaker (installation fuse) designed for operation in three-phase systems (3-pole), ensuring tripping selectivity and property protection.
Rated current
20 A - the current value at which the device can operate continuously without tripping the protective elements under normal ambient conditions.
Number of poles
3 poles (3P) - enables simultaneous disconnection of three phases in three-phase circuits, which is crucial for the protection of motors and advanced machinery.
Tripping characteristic
Type B - intended for the protection of cables and receivers in domestic installations (lighting, sockets) with low inrush currents.
Rated short-circuit breaking capacity
6000 A (6 kA) - the maximum short-circuit current that the circuit breaker is able to safely interrupt without damaging its structure.
Rated operating voltage
230 V AC / 400 V AC at 50 Hz frequency - standard operating parameters for European low-voltage electrical grids.
Rated frequency
50 Hz - optimal operating frequency ensuring correct magnetic and thermal characteristics of the device's releases.
Type of electrical terminals
High-quality screw (cage) terminals that guarantee high clamping force and minimal contact resistance at the wire-device interface.
Supported wire cross-section
Wide range from 1 mm² to 25 mm², which allows for the use of both rigid wires and flexible cables (with ferrules).
Operating status indicator
Integrated mechanical indicator of main contact position, informing about the actual disconnection state of the circuit regardless of the lever position.
Safety and sealing
The design allows for the installation of security seals, which is required by energy suppliers to protect against illegal power consumption or changes to the installation.
Housing material and construction
Made of non-flammable plastic with a high CTI index, providing excellent electrical insulation and resistance to mechanical impact.
Mechanical mounting method
Latch on standard DIN TS-35 rail (35 mm), allowing for quick assembly and disassembly without the need for specialized tools.
Width in modules
3 modules (17.5 mm per module), which gives a total width of 52.5 mm in the electrical distribution board row.
