10.3 MCCB/ELCB (Molded Case Circuit Breaker/Earth
Leakage Breaker)
Install MCCB (molded case circuit breaker) or ELCB (earth leakage breaker) in the primary circuit
(power supply circuit) of the servo amplifier to protect the servo amplifier against losses caused by the
power switching current and short circuit current. Models for a single servo amplifier are described
here. Because the servo amplifier is provided with protective functions against output circuits such as
the overcurrent, protective devices such as the thermal relay are unnecessary.
