FEATURES

Increased Dielectric Performance
The 10-VPR-40C(D)/50C(D) 4000AVCB exceeds IEC standard applicable requirements including longer
creepage and longer insulation distance that ensures breaker operation even under the most severe
environmental conditions.

New Technology Improves Maintenance
The design of the BH-1H incorporates low maintenance technology such as a newly developed low friction
greaseless surface treatment and long-life lubrication (lubrication cycle of six years).

Safety firs, t
Mitsubishi s design features multiple mechanical and electric interlock systems that ensure safe operation
and maintenance.

Our proven supply record proves our top quality
More than 500,000 Mitsubishi Vacuum Circuit Breakers have been produced since 1969.

Design for worldwide applications
The compact design of the VCB and optional mounting frame with shutter makes the unit suitable for a wide
range of replacements for existing or obsolete metal-clad and switchboard units.

designed/manufactured as an indoor unit. Therefore, this circuit breaker 2. Ambient temp: –5°C ~ 40°C
should be operated under normal environments specified in table 21. Daily and
periodical check and maintenance should be carried out enough according to (The average temperature for 24 hours must not
VCB's instruction manuals. If it is necessary to operate this circuit breaker exceed 35°C.)
under special condition not listed in table 21, consult the manufacture.
3. Relative humidity: 45% ~ 85%
●Instructions for Installation (Relative humidity; there must be no dew condensation.)
If it is necessary to operate this circuit breaker in a dusty place, a place with
corrosive gas, at a location exposed to abnormal vibration or impact, or in an 4. Degree of pollution: There must be no pollution.
outdoor panel environment, etc., special care must be paid to deal with items (As a guideline, the equivalent salt deposit density
such as dust, corrosion, vibration, impact, water drops, condensation, and etc. should be less than 0.01 mg/cm2)

5. Poisonous gas etc.: There must be no corrosive gas.
6. Powder dust: There must be no excessive powder dust.

(As a guideline, the powder dust should be less
than 2 mg/m3)

■ Application of Surge Protection Device

For the actual applications of vacuum circuit breaker, the surge protection standards for the load circuit so used, and actual
application will be shown as table 22. Use the as table 22 of standard bellows as reference when selecting models.

●Surge Protection Standards

37 Notes: 1. To directly switch the semiconductor rectifier unit (for example, electric power thyristor rectifier unit) in the secondary side of a transformer, use the transformer with
contact-protective plate. Provide a general-purpose arrester in the primary side and the surge protective device such as a filter capacitor in the secondary side.

2. Avoid interrupting the no-load excitation inrush current of molded transformer. When such currents must be interrupted, apply general-purpose arrester. To use
any molded transformer made by other manufactures, consult the manufacturer. However, low-surge VCBs require no general-purpose arrester.

3. For motors in applications where inching is the predominant switching duty (cranes, conveyor, etc.), use CR suppressor.
4. Mitsubishi molded transformer and oil transformer are for 6kV with the impulse withstand voltage 60kV and for 3kV with the impulse withstand voltage 45kV.
5. In case of kondorfer starting system, carry out the switching operation of the neutral point of the auto-transformer after the starting current become the

stationary.

■ Service Life and Application

The service life of vacuum circuit breaker is specified in the terms of the vacuum service life of vacuum switch tubes,
electrical and mechanical service lives.

●Vacuum Service Life of Vacuum Switch Tubes (VST)
Since the vacuum circuit breaker maintains the switching characteristics and insulation characteristics by using high
vacuum in VST, it is most important to maintain such vacuum. VST produced by our own original quality control is
checked severely by full-lot testing, and therefore can be operated safely for a long time. It is also possible to check the
vacuum in a simple way by voltage-resistance method in periodical maintenance. Portable type vacuum checkers are
also available.

●Electrical Service Life of VST (see Table 23)
The electrical service life of VST is determined by the electrode consumption and the number of switchings. In VCB,
such service life can be judged by the number of load switchings, because the electrode consumption is extremely small.

●Mechanical Service Life (see Table 23)
This can be determined by the operation counter provided in the vacuum circuit breaker (provided in all types as
standard specification).

●Replace when having reached at the service life
When it reached mechanical life or 20 years have passed since it was manufactured, it is necessary to replace the VCB.

2. Applicable capacities with 6 ~ 13% series-connected reactor are
shown.

■ Polarity of Main Circuit Connection

It is needless to classify the polarity in the power/load sides in connecting the top and bottom main circuit terminals of the
vacuum circuit breaker. (Electrical or mechanical performance is not changed whether it is connected to the power side or
load side.)
