Legrand DX3 modular bipolar circuit breaker with 32A C curve rating, offering 36kA breaking capacity at 400V and 72kA at 230V. IP20 protected terminals with red/green status indicator for reliable electrical circuit protection and isolation.
The Legrand DX³ MCB (Miniature Circuit Breaker) is a modular bipolar thermal-magnetic circuit breaker designed for control, protection and isolation of electrical circuits in residential and small commercial applications. This robust device offers exceptional breaking capacity of 36kA at 400V and 72kA at 230V, ensuring reliable protection against overcurrent and short-circuit faults. The C curve 32A rating makes it ideal for circuits with moderate inrush currents, such as lighting and general-purpose loads.
With its compact 3-module width design and IP20 protection rating, this circuit breaker provides fingerproof terminals protected against solid bodies larger than 12.5mm, ensuring safety during installation and operation. The device features a red/green mechanical indicator that clearly displays the open or closed status of contacts, and includes a convenient label holder for circuit identification. Built-in depth of 47mm allows for easy integration into standard DIN rail mounted distribution boards.
The DX³ breaker is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, providing flexible system expansion capabilities. Engineered with environmental consciousness, this halogen-free device complies with substance-restriction requirements and operates reliably across ambient temperatures from -25°C to +70°C. The screwed terminal connection supports both solid-core conductors (1.5-50mm²) and multi-wired conductors (1.5-35mm²), accommodating various cable types for flexible installation options.
