NES12 / medium voltage switchgear as withdrawable unit technology

NES12 – The new generation of medium-voltage switchgear technology

With the NES12, we are presenting the next evolutionary stage in modern switchgear: compact, powerful, and consistently designed for future-proofing. Its innovative architecture combines maximum technical precision with maximum user-friendliness – for a new level of efficiency in planning, installation, and operation.

Maximum performance in minimum space
The NES12 impresses with its extremely compact dimensions and modular design, which enables flexible system concepts. Thanks to its sophisticated construction, it remains powerful – even with small field divisions.
High current without compromise
The rated field current corresponds to the circuit breaker's rated current – without any derating. The NES12 thus offers clear technical superiority and maximum planning and operational reliability, even in demanding applications.
Optimized for everyday use.
The NES12 has been consistently developed for real-world plant operation in primary energy distribution:
• Optimized power cable connection for fast, safe installations
• Improved accessibility for auxiliary drives and limit switches – ideal for working in medium-voltage bulkhead rooms
• No forced ventilation required in high-current fields – reducing effort, operating costs, and susceptibility to faults
Sustainable. Resource-efficient. Future-proof.
With reduced material usage and a significant minimization of plastics, the NES12 sets an example in sustainability. At the same time, its air insulation makes it future-proof and independent of potentially critical insulation media.
