RVZ 10/630-III Three Pole Disconnector

RVZ are designed for operation in alternating current networks with a frequency of 50 and 60 Hz, at rated voltage 10 kV and are intended:
– for disconnecting and switching on energized sections of the electrical circuit high voltage in the absence of load current or to change the circuit connections;
– to create a visible break in the chain for the purpose of safe work on disconnected area;
– to turn on and off the charging currents of overhead and cable lines, current no-load current of transformers and currents of small loads;

Technical Specifications

Working Principle

The RVZ 10/630-III disconnector operates through simultaneous movement of three contact blades mounted on a common shaft. During operation, the switch provides visible electrical isolation for maintenance safety. Integrated earthing blades allow grounding of disconnected sections, while mechanical interlocking prevents incorrect switching sequences between main and grounding contacts.

Applications

The RVZ 10/630-III disconnector is widely used in:

• Indoor switchgear panels
• KSO and KRU switchgear
• Compact transformer substations (KTP)
• Medium voltage distribution systems
• Industrial power distribution
• Utility substations
• Capacitor banks
• Incoming and outgoing feeder panels

Product Advantages

Enhanced Operational Safety

Dual-side earthing blades provide improved grounding protection during maintenance operations.

Reliable Mechanical Interlocking

Prevents simultaneous closing of grounding and main contact blades.

Compact Indoor Design

Suitable for medium voltage switchgear cabinets and compact substations.

Durable Construction

High-strength frame and quality contact materials ensure long service life and low maintenance.

Optional Configurations

• Polymer insulators
• Porcelain insulators
• Left-hand or right-hand operation
• PR-10 operating mechanism
• Auxiliary contacts
• Customized mounting dimensions
