Modular Devices
The Company
Larsen & Toubro is a technology-driven company
that infuses engineering with imagination. The
Company offers a wide range of advanced solutions
in the field of Engineering, Construction, Electrical &
Automation, Machinery and Information Technology.
L&T Switchgear, a part of the Electrical & Automation
business, is India's largest manufacturer of low
voltage switchgear, with the scale, sophistication
and range to meet global benchmarks. With over five
decades of experience in this field, the Company
today enjoys a leadership position in the Indian
market with a growing international presence.
It offers a complete range of products including
powergear, controlgear, industrial automation,
building electricals & automation, reactive power
management, energy meters, and protective relays.
These products conform to Indian and International
Standards.
L&T�s Tripper range of modular devices offer
MCB, RCCB, RCBO, Isolator & DB for final
distribution of electrical power.
L&T�s products are better known for reliability,
functionality & ease of use.

Tripper products conform to relevant
global standards viz., IEC, EN They
also have marking & CB,
certification.
Tripper modular devices spell world class
Safety re-defined
Finger proof terminals eliminate chances of accidental contact with live part.
You can install, operate and maintain Tripper with total confidence.
IP20FingerproofTerminals
Two position DIN rail clip
Installation on a DIN rail is further simplified with a two-position DIN rail clip
as a standard feature. Tripper range makes mounting on a standard DIN rail
more convenient than most.
8.5 kA
Energy limiting class - 3
If fault occurs, the Rapid Arc Quenching mechanism in Tripper operates and
extinguishes the arc quickly (within 3 - 5 msec), ensuring lowest possible
energy flow through the circuit. This minimizes risk of fire and maximizes life
of your equipment.
Large terminal size and dual termination
Tripper can easily accommodate cables of up to 35 sq. mm. The terminals
are designed to facilitate termination of cable or bus bar or both at incomer
side. Tripper terminals offer simple termination flexibly.
L&T wire
OR / AND
Non-welding contacts
Silver Graphite contact tips ensure higher life and maximum safety against
contact welding due to its superior anti-welding properties, enhancing
safety and life of the system.
Combihead screw
Tripper range of products provided with combihead screws, allow you to use
standard as well as Philips screwdrivers. Tripper range addresses your
undefined needs.
Safety meets superior aesthetics
Ergonomically designed, profiled for superior cooling and manufactured
with fire retardant material. Tripper is brought to you keeping in mind utmost
user safety.
Innovatively profiled breathing channels
When two or more poles are placed adjacent to each other, the breathing
channels are so profiled that the air circulates around individual pole,
resulting in cooler operation. Tripper range operates coolest year after year.
True contact indication
Tripper range enhances safety through true contact indication even from a
distance regardless of its mounting and knob position. Red and Green
indication tags provided below the knob positively identify the electrical
ON/OFF status, reflecting actual contact status.

Working Principle
Human body�s reaction to electric shock
Electrical shocks passing through the human body,
affect its internal nervous system. This causes the
body to react to the passage of current as follows:
3mA : A tingling sensation is felt.
10-15mA : Muscle spasm and tightening occurs.
20-30mA : The heart may fibrillate; severe shock is felt.
>50mA : Lethal. Fibrillation of the heart occurs.
