SIEMENS SION and SIMOSEC Core Parts A Perfect Combination Owner’s Manual

Instruction

SION vacuum circuit-breakers 3AE6 Lateral – for all switching tasks in medium- voltage distribution systems – are suitable for installation in all common, new, reinsulated medium-voltage switchgear. However, thev vacuum circuit- braker is also ideally suited for retrofit measures in existing switchgear.

The combination of SION with the 3-position alternating current switches from the SIMOSEC Core Parts product range makes the use of the SION vacuum circuit- breaker even more universal.

The slim design of the circuit-breaker is matched to the size of the enclosed isolators from the SIMOSEC Core Parts. Disconnectors and circuit-breakers can thus be combined without any problems. For switchgear manufacturers, the advantage is that they have access to factory-manufactured and type-tested individual components, ready for installation in an air-insulated switchgear panel.

SIMOSEC core parts and SION vacuum circuit-breakers are alsoavailable in ready-made cubicles from the SIMOSEC series.

You benefit from a type-tested, air-insulated, modular switchgear with high reliability and successful operation since 2001 with an experience value of more than 1,500,000 bay units of the 8DJH, 8DJ, 8DH and SIMOSEC series.

Your advantages with the SION/SIMOSEC combination

SION vacuum circuit-breaker 3AE6 stands for safe switching in medium-voltage systems – high reliability and availability
Maintenance-free circuit breaker up to 10,000 switching cycles
- Without relubrication
- Without readjustment under normal ambient conditions according to IEC 62271-1
Due to the compact design, universally applicable, also for retrofits
SIMOSEC switchgear benefits from long production runtime and large quantities
High life expectancy, minimum maintenance
Easy expansion through screwed field-to-field connections

Application area

SION vacuum circuit-breakers are used for switching overhead line and cable feeders, transformers, capacitors, and motors.

Panel grounding variants

Via CB: Three-position switch in position “Grounded” + CB in “ON”
Separate earth switch (ES) – Only for outgoing feeder panel
