NOTE:
Fuse ratings are based on 250V fuses for 230V inverters and 600v for 460V inverters.
13.0 Applicable Specifications for Circuit Breakers and Magnetic Contactors
The following tables show the specifications for molded case circuit breakers and magnetic contactors vs N3 models.
Table 13.1A (230V)
Table 13.1B (460V)
!
CAUTION
TECO bears no responsibility for failures caused by the following conditions:
( 1 ) A molded-case circuit breaker is not installed, or an improper or overrated
breaker is used between the power source and the inverter.
(2) A magnetic contactor, a phase capacitor, or a surge suppressor between the
inverter and the motor.
