Special operating conditions

If the vacuum circuit-breaker is operated under unfavourable conditions indoors
(heavy and frequent condensation, dusty air, etc.), we recommend cleaning the in-
sulating parts and possibly the outer parts of the circuit-breaker at shorter intervals.

Service life of the vacuum interrupters

If switching operations occur frequently under overload or short circuit, the service
life of the vacuum interrupters may be reached prematurely.

Accessories and spare parts

Replacing spare parts

To ensure that the switchgear operates reliably, spare parts must be replaced only
by trained and certified personnel.

Fig. 62

Accessories available for order

Always specify the vacuum circuit-breaker's type and serial no. (see “Name plate”
on page 28) when ordering spare parts.
Accessories and spare parts can be found in Catalogue HG11 or requested from the
responsible Siemens representative.

Manufacturer's product liability

The manufacturer's product liability shall be excluded if at least one of the following
criteria applies:
• Original Siemens spare parts are not used.
• Fitters carrying out replacements have not been trained and certified by Sie-

mens.

• Parts have been incorrectly fitted or adjusted.
• Adjustments are not made in accordance with Siemens specifications.
• After installation and adjustment, no final test is performed with a tester

approved by Siemens including documentation of the test results.

To keep documentation complete, it is important that measurement results are sub-
mitted to the responsible Siemens representative.

CAUTION

Risk of injury!

The vacuum circuit-breaker should be taken out of the switchgear or switch cab-
inet for servicing.

Separate vacuum circuit-breakers from the control feed voltage or switch it off
and release low-voltage plug or clip connection.
