■ The LT6-P electronic multifunction protection relay is ideally
suited to high performance applications. It provides protection
for your motors in virtually any application or operating condition.
■ It enables automatic control of different methods of starting:
■
cross-line (reversing or non-reversing)
■
star/delta
■
2-speed
■ All the functionalities are programmable with parameters entered
locally or using a PC software.
■ It integrates into all the most complex automation systems
through its communication functions on UNITELWAY
®
,
JBUS
™
, MODBUS
®
protocols.
■ The LT3-S thermistor relay provides complementary protection
by direct measurement of the temperature of motors equipped
with PTC thermistor probes, for operation:
■
in hard ambient conditions: high temperature, dust, humidity
■
with severe duty: fast operating cycles, use of DC injection braking.

INTEGRAL
™
Self-Protected Starters
TELEMECANIQUE
®
INTEGRAL self-protected starters combine
circuit breaker, contactor and dual function overload relay for
coordinated circuit protection. INTEGRAL starters are the only self-
protected starters to have UL/CSA verification for Type 2 coordinated
protection. INTEGRAL starters can reduce panel space requirements
by 40 to 60%. 18A, 32A and 63A models are available.

Manual Starter and Protector
The TELEMECANIQUE GV2 and GV3 devices incorporate a manual
disconnect, overload relay and instantaneous magnetic trip mechanism
in one compact device. They can be used as standalone manual
starters or to protect each branch circuit of a group motor installation.

Enclosed IEC Starters
D-Line starters and INTEGRAL self-protected starters are available
in metal NEMA Type 1 and 12 enclosures. These enclosed devices
utilize INSTAKIT
™
components for the addition of cover mounted
pilot devices. INSTAKIT components are pre-wired control operator
kits that use a universal connector for quick, easy installation.
