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.

Integrated label holder

Tripper MCBs are equipped with label holder for easy identification of circuit

during operation as well as in maintenance.

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.
