## Summary description

Legrand TX3 miniature circuit breaker Type D 3 rated at 25 A for protection of electrical circuits in residential and commercial installations. Designed for use on 240–415 V systems at 50–60 Hz, with IP20 protection. Provides overcurrent/tripping protection with Type D characteristic suitable for circuits with moderate inrush currents.

## Long description

Legrand TX3 miniature circuit breaker Type D, rated 25 A, designed for protection of electrical circuits in residential and commercial installations. Intended for low-voltage systems with nominal voltages from 240 to 415 V and operating frequencies of 50–60 Hz. The device has IP20 enclosure protection and a Type D tripping characteristic that responds to moderate to high inrush currents.
Advantages
The TX3 Type D breaker combines compact size with reliable overcurrent protection for three-pole circuits. Its Type D characteristic provides selective tripping for circuits with motors, transformers or other loads that produce significant starting currents. Installation on standard DIN-rail panels is straightforward and the IP20 rating offers basic protection against solid objects.
Suitable for
 Protection of three-phase circuits in small commercial or residential electrical panels
 Circuits with motors, transformers or lighting with moderate inrush currents
 Applications requiring a compact, DIN-rail mounted overcurrent device
When it may not be suitable
This breaker is not intended for outdoor use or environments where higher ingress protection is required, since IP20 only protects against access to hazardous parts and not against water. It may also be unsuitable for circuits that need more sensitive tripping (e.g., electronic loads with low inrush) where a B or C characteristic, or residual-current protection, would be preferable.
Key specifications
 Type: D tripping characteristic
 Number of poles: 3
 Rated current: 25 A
 Rated voltage range: 240–415 V AC
 Rated frequency: 50–60 Hz
 Protection degree: IP20
How to use
Mount the breaker on a compatible DIN-rail inside an electrical distribution board, connect the three-phase supply and load conductors to the corresponding terminals, and ensure correct tightening to the manufacturer’s torque recommendations. Verify the system voltage and select appropriate downstream wiring and protective devices. Test the installation by switching the breaker on and off and checking for correct tripping behavior under defined test conditions.
What to consider before purchase
 Confirm system voltage and frequency match the 240–415 V, 50–60 Hz rating
 Ensure a Type D characteristic is appropriate for your load inrush profile
 Verify required ingress protection; IP20 is not suitable for wet or outdoor locations
 Check panel space and DIN-rail compatibility for a three-pole miniature breaker
Usage recommendations
Use this Legrand TX3 Type D 3-pole breaker for three-phase distribution circuits with motors or transformer loads where moderate to high inrush currents occur; coordinate with upstream and downstream protective devices and follow local electrical codes when installing.
