Ang drive module ay ginagamit kasama ang circuit breaker, na naglilingkod bilang kontrol at online monitoring device para sa circuit breaker system. Ang kaso ng drive module ay gawa sa aluminum alloy, na maaaring mabawasan ang electromagnetic interference, kasama ang limang unit circuits:
Switching power supply unit: Nagcoconvert ng external auxiliary power supply sa power source na ginagamit ng internal circuit.
Charging circuit unit: Nagsasave ng electrical energy para sa closing at opening capacitors.
Discharge circuit unit: Nagsisilbing mag-inject ng positive excitation current o reverse demagnetization current sa excitation coil ng circuit breaker mechanism upang makapagtanggal o mapagbigay ng magnetismo sa mechanism.
I/O interface unit: Ginagamit ito para tumanggap ng opening at closing commands pati na rin ang input ng estado ng circuit breaker.
Control Unit: Monitors at controls ang operasyon ng buong circuit breaker.
Pangunahing function

Magbigay ng de-magnetizing current para sa opening operation
Online monitoring
Babala para sa abnormal na movement ng auxiliary switch
Manual trip alarm
Anti-jump at locking function
Ang drive module mismo ay may function ng anti-jump locking
application
Pag-drive ng MS Series circuit-breaker
