Standards & Approvals

A CE marking is a European marking of conformity that indicates a product complies with the essential requirements of the applicable European laws or directives with respect to safety, health and environment and consumer protection. Generally, this conformity to the applicable directives is done through self-declaration and is required on products in the countries of the European Economic Area (EEA) to facilitate trade among the member countries. The manufacturer or their authorized representative established in the EEA is responsible for affixing the CE marking to their product. The CE marking provides a means for a manufacturer to demonstrate that a product complies with a common set of laws required by all countries in the EEA to allow free movement of trade within the EEA countries.

L&T’s conform to the Low voltage directive 73/23/EEC as amended by directive 93/68/EEC, provided it is used in the application for which it is made and is installed and maintained in accordance with professional practices with relevant installation standards and operating instructions.

Marking

NABL accreditation is a formal recognition of the technical competence of testing, calibration or medical laboratory for a specific task following ISO/IEC 17025:2005 Standard. Accredited laboratories have the responsibility of satisfying the criteria of laboratory accreditation at all times, which are verified during Surveillance and Reassessment visits by NABL. Further the accredited laboratories should prove their technical competence by satisfactory participation in recognized Proficiency Testing Programmes.

L&T’s Switchgear Testing Lab is NABL accredited subject to continued satisfactory compliance to above standard & additional requirements of NABL.

Switch- range is tested in L&T's NABL accredited Switchgear Testing Lab.

FN S-D Product Features

1. Handle

The FN Switch has a unique operating handle with thefollowing features.• Door interlock for safety of operating personnel when switch

is ‘ON’. The interlock can be defeated if required• Built-in padlocking arrangement to lock the unit in ‘OFF’

position• The handle coupling can take a mismatch or ± 3mm in all

directions• IP54 with extended operating handle

2 . Maximum termination capacity

3. Ground clearance

FN switch range provides generous terminal capacity in its compact size, facilitating aluminium termination.

Higher ground clearance between terminals and mounting base plate ensures adequate clearance even after connecting cables. This eliminates the possibility of phase to ground flash over.

4. Positive ON / OFF indication of S-D

The FN Switch indicates true position of contacts. (By a red pointer)

5. Built-in neutral

The FN TPN Switch consists of an integral neutral, making the units suitable for 3 phase, 4 - wire application. FN 32 / 63 has switched neutral while higher ratings have isolable neutral. (For higher ratings switchable neutral kit is available as an accessory)

6. Contact system

Contact system is QUAD BREAK. There are number of parallel moving contacts per pole per break. Hence, better arc quenching & more electrical life of contacts. Each pole has separate bridge carrying the moving contacts, achieving a high order of inter phase separation & avoiding phase-phase flash over.

S-D Product Features

1. Handle

The C-line Switch has a unique flip-able operating handle which enables user to operate the switch with two hands. The handle also offers the following.

Features:• Door interlock for safety of operating personnel when switch is ‘ON’.

The interlock can be defeated if required• Built-in padlocking arrangement to lock the unit in ‘OFF’ position with

3 padlocks of Ø5 to Ø7• IP54 with extended type operating handle

2. Terminal shroud

These shrouds provide complete touch proof design and prevent accidental touching of live terminals. They are click fit type. Due to hinge type terminal shrouds, it can be turned by 90 degree, hence terminals can be inspected without removing these shrouds.

3. Inter-phase barriers

Inter-phase barriers are provided for additional safety to eliminate possibility of inter-phase short-circuit.

4. Positive ON / OFF indication of S-D

The C-line Switch indicates true position of contacts.

5. Depth adjustable operating shaft

The C-line Switch depth can be varied and fixed as per requirement during installation which is possible due to stepless adjustment of operating shaft.

6. Mechanism and Contact System

Contact system is of double break, knife type having self wiping action with electrodynamic compensation. This ensures reliable performance during normal as well as short circuit fault conditions, offering higher short-time withstand rating.

C-line switch offers high electrical and mechanical life in compact size. The electrical and mechanical life are two times the requirement of the standard.
