Answer Posted / s. rahimzadeh
Contactors take palce against the circuit breakers (not
relays). Contactor acts like a circuit breaker and
similarly can get its command from a relay. Relays are used
for detecting the conditions which the circuit switch
(Circuit breaker or Contactor) should cut the circuit.
