L&T-Ti TTA PANELS
as per IEC-61439-1&2
The new Ti range LV switchboards are design and verified with Aluminium and copper busbars, providing the perfect balance of cost-effectiveness, compactness and safety. Type-tested Ti switchboards are the perfect solution to optimize processes and contribute to long-term profitability.
When dealing with electrical systems, there are no second chances. Ti is equipped with a range of safety features to safeguard your system as well as the people who operate it.
Design verified for Safety:
Ti is a design-verified assembly, in accordance with IEC 614391&2, assuring you of the highest levels of quality and safety, from design to assembly
Busbars in the Ti range have higher clearances than those prescribed by global switchboard standards (25 mm – Ph to Ph and 19 mm – Ph to N/Phto E), offering a superior level of safety.
No accidental contact:
A rotary knob ensures that an operator does not come in contact with live terminals or parts during maintenance.
Form of separation:
Compartmentalized design up to Form 4B as per IEC 61439-2.
Zero ‘stray-voltage’ doors and panels:
It’s panel doors are designed to prevent accidental opening. We have also placed earthing contacts on every door and an Earth bar running the length of the switchboard, connected to structural members, These ensure that the outer surfaces do not have stray voltages, as this could harm an operator.
Enhanced ingress protection:
A Minimum ingress protection of IP2X is provided even with the doors open to ensure that an operator does not come in contact with live terminals or parts during maintenance.
The Busbars in the Ti range are equipped with polyester glass supports for insulation. You also have the choice to install heat-shrunk PVC sleeves for extra protection.
Designed For Convenience:
The Ti range incorporates a number of features that help make installation and maintenance easy.
Compactness Spells Cost-Effectiveness:
Ti offers flexibility and customization to suit your space requirements, ensuring that you maximize value on the space available to you.
