GN24-12D 12kV Indoor Isolator Switch | Compact HV Isolator

Safe and Reliable Power Isolation for 12kV Indoor Systems

The GN24-12D indoor  isolator switch is a high-voltage isolator designed for 12kV medium-voltage switchgear. Engineered for safe disconnection during inspection, maintenance, and equipment replacement, it features visible breaking contacts, strong arc resistance, and compact dimensions for space-constrained indoor substations.

Compliant with IEC 62271-102 and GB 1985, this unit is widely installed in factory power distribution rooms, urban substations, and renewable energy control cabinets.

Core Features

• Compact Indoor Design
  Ideal for panel-type switchgear or distribution enclosures where space is limited.

• Visible Isolation Contacts
  Supports operator safety by allowing direct visual confirmation of disconnection.

• Robust Arc-Resistant Contacts
  Minimizes oxidation and ensures low contact resistance over long service periods.

• Flexible Mounting
  Can be wall-mounted or integrated within metal-enclosed switchgear units.

• Easy Manual Operation
  Equipped with a spring-assisted handle and mechanical locking.

Application Scenarios

• Urban Power Distribution Cabinets
  Compact form factor makes it ideal for inner-city 12kV control rooms.

• Solar and Wind Power Collector Rooms
  Used in DC-to-AC conversion stations for equipment isolation.

• Industrial Plant Medium Voltage Rooms
  Often deployed in automotive and steel plants for line-side disconnection.
