Legrand DX³ (AC) | 415V 40A 3P MCB (C Curve)

The Legrand DX³ Miniature Circuit Breaker (MCB) is a high-performance thermal-magnetic device designed for the demanding requirements of commercial and industrial electrical installations. This specific model, rated at 415V and 40A, is a robust 3-pole (3P) unit, engineered to provide essential control, protection against short-circuits and overloads, and effective isolation of AC electrical circuits.

Featuring a C-Curve tripping characteristic, this MCB is ideally suited for managing loads with moderate inrush currents, such as standard motors, pumps, fans, and general everyday equipment. The C-Curve ensures reliable protection by magnetically tripping when the current reaches 5 to 10 times the rated 40A current.

Part of Legrand’s DX³ range, this MCB offers high breaking capacity, with comparable models in this specification often rated for 10kA, guaranteeing enhanced safety and durability under fault conditions. Its design emphasizes improved safety, ease of operation, and versatility, with a built-in depth of 47 mm and a wide operating temperature range of -25 to 70 °C. The DX³ series provides professional-grade overcurrent protection, ensuring the longevity and safety of your electrical infrastructure.
