Legrand TX3 istič MCB C 32A 3-polový 10kA 400V AC 3 moduly 404225

The Legrand TX3 miniature circuit breaker (MCB) delivers robust overcurrent and short-circuit protection for commercial and industrial electrical installations. With a rated current of 32 A and a 10 kA breaking capacity at 400 V AC, this 3-pole device ensures reliable disconnection under fault conditions, safeguarding cables and connected equipment. Its Type C tripping characteristic (5–10 In) makes it ideal for circuits with moderate inrush currents, such as motors, transformers, and lighting banks.

Advantages

The TX3 series combines high performance with ease of installation. The compact 3-module width (54 mm) saves valuable space in distribution boards, while the DIN rail mounting and screw terminals with wide capacity (1–25 mm² solid, 1–16 mm² flexible) simplify wiring. Certified to EN 60898-1, this MCB offers long-term reliability with an electrical endurance of 10,000 cycles and mechanical endurance of 20,000 cycles. Its IP20 protection and operating temperature range of -25 °C to +70 °C ensure suitability for diverse environments.
