Please note that a standard AC fuse should NOT be used in a DC circuit. The fuse must

be SPECIFICALLY labeled for DC applications. For most larger motor applications, a

600A fuse will be sufficient. Application-specific fuses can be ordered directly from EPC.

Also note that standard 125-volt and 240-volt DC circuit breakers (such as the AirPax

JLM-1-1RLS5-30140-200) will NOT function correctly because of the high voltage present

when the motor's windings are discharged during normal operation. If using a circuit

breaker, it must have a DC break rating higher than 600 volts.

CONTACTORS

A pair of contactors, or some other type of high-speed mechanical disconnect should be

installed near the power supply. This not only allows for easy servicing, but can protect

the motor and controller in the event of a short or system failure. Contactors are

REQUIRED for all electric vehicles running DC motors.

CONTROLLER PROTECTION

YES

Pictured is a Curtis SW-200 Contractor. Contactors should

have a continuous rating of at least 200 amps, with a surge

capacity of about 1000 for this controller. Magnetic

blowouts are required.
