Motor protection solutions
T8 2000A 3 poles with PR332 LSIG
General circuit-breaker used for protecting the load side
circuit-breakers dedicated to motor protection.
T8 800A 3 poles with PR221-1
Circuit-breaker used for motor protection in conjunction with
a thermal relay and a contactor. Instantaneous short-circuit
protection (I) can be adjusted from 1 to 10xIn.
XT4 250A 3 poles with Ekip M-LRIU
Circuit-breaker used for integrated motor protection.
Ekip M-LRIU is fitted with the following protections:
• against overload (L): threshold adjustable from 0.4...1xIn.
The tripping time is established by choosing the tripping
class defined by standard IEC 60947-4-1.
• rotor locking (R): with threshold adjustable in OFF or from
3...9x I1, with adjustable tripping time;
• against instantaneous short-circuit (I): with threshold
adjustable from 6...13xIn and instantaneous tripping time;
• against phase imbalance (U): with threshold adjustable
in ON or OFF.
XT2 160A 3 poles with MA
Circuit-breaker used for motor protection in conjunction with
a thermal relay and a contactor. Instantaneous short-circuit
protection (I) can be adjusted from 6...14xIn.
