Electrical and digital building infrastructures company Legrand’s portfolio of miniature circuit breakers (MCBs) offers solutions for efficient protection, enhanced safety and continuity of service in commercial, industrial and domestic applications.
New to the company’s MCBs is the TX3 series, designed for safe installation and maximum protection of people and property in modern commercial and residential installations.
Included in the new TX3 range are thermal magnetic circuit breakers and residual current devices.
“Legrand’s modular products are continually upgraded for improved efficiency and safety, enhanced aesthetics, simple installation and greater energy savings. “The TX3 range, which meets stringent quality, safety and environmental specifications, offers protection against short circuits, overloads and residual current faults,” says Legrand South Africa projects and technical coordinator Marc Naidoo.
The TX3 range has unique features to save time and ensure safety at each stage of the installation. A bi-stable clip ensures easy positioning or removal of the circuit breaker on the DIN rail.
A DIN rail is metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks.
Moreover, clear marking on the front panel ensures quick visual identification of relevant information such as the pro- duct name, position of contacts, curve type, rating, breaking capacity and the limitation class.
Naidoo notes that Legrand offers a wide range of control and signalling auxiliaries for flexibility in installations. These auxiliaries are used in conjunc- tion with TX3 and DX3 circuit breakers to monitor and control circuits remotely in commercial installations. Components, which are available in 0.5 mm widths or one module wide, include auxiliary and fault signal contacts, shunt trips, undervoltage releases and motor- driven controls.
Signalling auxiliaries have a wide range of functions, including an auxiliary changeover switch that indicates the position of the contacts of the MCB and a fault signal- ling changeover switch which indicates the opening on a fault.
Naidoo states that auxiliaries are equipped with retainer clips for quick, tool-free mounting on the left-hand side of the MCB.
As such, terminals with visible, accessible screw heads facilitate easy wiring and the arrow on the front of auxiliaries identifies the circuit breaker to which they are linked. Possible configurations are three auxiliaries per device, including one control auxiliary, as well as the insertion of the supply busbar.
The company’s comprehensive range of power equipment encompasses moulded-case MCBs, surge protectors, modular distribution blocks, air circuit breakers, cast resin transformers and capacitors, as well as industrial sockets and wiring accessories.
