Page 12 INSTALLATION
Do not install this
equipment in areas where
unusual service conditions
exist. Using this equipment
in other than usual service
conditions can result in
equipment failure.
Toshiba HV6FS-MLD circuit breakers are
intended for use in usual service conditions as
defined in IEEE C37.20.2. The temperature of
the cooling air (ambient air temperature)
surrounding the breaker should be between the
limits of -5°C (23°F) and +40°C (104°F). The
altitude of the equipment installation should not
exceed 3300 ft (1000 m).
In particular, avoid the following installation
conditions:
- Excessive dust
- Corrosive gases
- Extreme variations in temperature
- Very high or low humidity
- Vibrations
- Inclined locations
If there is a chance that condensation can occur
Fig. 10 Typical Circuit Breaker Nameplate
at the installation location, a space heater should
be installed inside the circuit breaker enclosure.
NOTE: Temperature, altitude or other
conditions outside of the usual limits
may require derating or other special
equipment. Contact your nearest
Toshiba representative for additional
information.
RATING VERIFICATION
Prior to Installation, the maximum fault current
capacity of the power system at the point of
installation should be verified. This value must
not exceed the symmetrical interrupting
capability of the circuit breaker. Fig. 10
illustrates a typical circuit breaker nameplate.
Do not exceed the ratings
specified on the circuit
breaker nameplate or
system accessories.
Underrated equipment can
fail during operation
causing fire, explosion,
severe injury, death, and
property damage.
