Product Description

Product Description

MOTOR CIRCUIT BREAKER - RELIABLE MOTOR PROTECTION
 
GV 3 motor circuit breaker is suitable for the circuit with AC voltage to 690V and current to 80A to realize short circuit and hot overload protection of the motor, and can also be used for infrequent line conversion or direct start of the motor. Widely used in machine tool equipment, grain machinery, textile machinery, generator set, large automatic control equipment, etc.

 KEY FEATURES & BENEFITS

Advanced Motor Protection:

Our motor circuit breakers provide comprehensive three-phase motor protection with adjustable current settings from 0.1A to 100A, ensuring optimal performance for various motor applications, including pumps, fans, compressors, and industrial machinery.
 
Intelligent Trip Characteristics:

Featuring thermal-magnetic trip technology with Class 10 or Class 20 trip curves, these breakers deliver precise protection against motor overload while preventing nuisance tripping during normal starting conditions.
 
Enhanced Safety & Control:

Built-in auxiliary contacts and manual reset functionality enable seamless integration with motor control centers (MCCs) and provide clear trip indication for maintenance teams.
