Specification
Device type
Three-phase miniature circuit breaker (installation fuse) designed for effective protection of electrical installations against the effects of overloads and short circuits in multi-phase systems.
Rated current
25 A - this is the value of the current that the circuit breaker can conduct continuously under specified ambient conditions without causing the tripping mechanism to actuate.
Number of poles
3 (three-pole) - the device ensures simultaneous disconnection of all three supply phases in case of a fault detection in any of them, which is crucial for the protection of motors and 3-phase devices.
Tripping characteristic
Type B - this characteristic is dedicated to the protection of cables and receivers in lighting, control, and socket circuits where there are no high inrush currents. The magnetic tripping threshold is in the range of 3 to 5 times the rated current.
Rated short-circuit breaking capacity
6000 A (6 kA) according to the EN 60898-1 standard. This parameter defines the maximum short-circuit current that the circuit breaker is able to safely interrupt without damaging its structure.
Rated voltage
400 V AC (alternating current) at a frequency of 50 Hz. The device is fully adapted for operation in standard European low-voltage networks.
Terminal type
Solid screw terminals that guarantee durable wire clamping and minimize contact resistance, which prevents excessive heating of connection points.
Selected additional features
The device offers the possibility of being equipped with a wide range of DX3 series accessories, such as auxiliary contacts, signal contacts, shunt trips, and undervoltage releases, which allows for the construction of advanced automation systems.
Mounting compatibility
The circuit breaker is adapted for power supply and connection using professional comb (fork) or pin busbars, which significantly shortens installation time and improves the aesthetics of the distribution board.
Housing and mounting
Made of high-class insulating material, resistant to fire and high temperatures. Mounting is performed on a standard DIN rail TS-35 (euro rail).
Modular width
The device occupies 3 standard modules with a width of 17.5 mm each, which gives a total mounting width of approximately 53 mm.
Information functions
On the front panel of the device, there is a dedicated, transparent labeling window that allows for the placement of a card with a description of the protected circuit, facilitating identification during operation.
Technical limitations
The design of this specific model does not provide for the possibility of direct mechanical connection of residual current blocks (separate RCD circuit breakers are required in the installation).
Warranty and standards
The product is covered by a full 2-year manufacturer's warranty (24 months). It meets all required CE safety standards and installation standards applicable in the European Union.
Manufacturer
LEGRAND - a renowned French manufacturer of electrical installation equipment, known for the highest quality of workmanship and innovative solutions in the field of energy distribution.
