Modular circuit breakers

Modular circuit breakers

The new TX³ and DX³ modular offer

Legrand offers you cutting-edge technical features with its range of TX³ and DX³ modular circuit breakers and differential protection. This range extends up to 125 A and meets all residential, tertiary and industrial applications requiring reliability, ease of cabling and performance (selectivity and coordination). 

 

 

Accessibility of the terminals 

Visibility and accessibility of the screw heads facilitate wiring 

Clear and simple marking 

The arrow marked on the front panel of the auxiliaries allows instant identification of the devices to which they are associated. 
 

Optimized space in the table 

Legrand's motorized control (ON/OFF) is the most compact on the market: 1 module wide. Motorized controls are combined with circuit breakers and differential switches. 

TX³ the offer for your daily installations

The 'standard' TX³ range includes circuit breakers that offer a solution for all installations in the residential and small commercial sectors. These circuit breakers are available with a breaking capacity of 3 kA and 6 kA and can be equipped with various auxiliary contacts.
