Miniature circuit breaker Legrand TX3 Type C 2 A 240–415 V IP20 35.4×77.8×88 mm

Legrand TX3 miniature circuit breaker Type C, 2 A, is designed to protect low-power circuits in residential and light commercial electrical installations. The device is compatible with supply voltages from 240 to 415 V and frequencies of 50–60 Hz. With IP20 protection and compact dimensions of 35.4 × 77.8 × 88 mm, the unit is intended for DIN-rail mounting in distribution boards where space is limited and reliable short-circuit and overload protection is required.

Advantages

The breaker offers selective tripping behaviour characteristic of a Type C curve, providing reliable protection for circuits with moderate inrush currents such as lighting and small motor loads. Its compact footprint and DIN-rail compatibility simplify installation in standard consumer units and small distribution panels. The IP20 rating ensures basic protection against accidental contact with live parts while maintaining accessibility for maintenance in enclosed electrical cabinets.

Suitable for

• Protection of lighting circuits and low-power outlets
• Small motor loads and appliances with moderate inrush current
• Residential distribution boards and small commercial panels
• Retrofit or new installations where space on the DIN rail is limited

How to use

Install the miniature circuit breaker on a standard DIN rail inside the distribution board following applicable electrical codes and safety procedures. Ensure the supply voltage and frequency match the rated values and that the protected circuit does not exceed the 2 A rated current. Make secure incoming and outgoing connections to the appropriate poles, verify the correct orientation, and tighten terminals to the manufacturer’s recommended torque. After installation, test the circuit to confirm correct operation and tripping behaviour before placing the system into regular service.

Usage recommendations

Use this Type C 2 A breaker for circuits with occasional moderate inrush currents, such as small motors and grouped lighting. Avoid using it on circuits with continuous currents close to the rated value; select a breaker with a higher rating if sustained loads regularly exceed 2 A. Periodically inspect connections and the enclosure for signs of overheating or corrosion and follow local regulations for inspection intervals.
