Rolf Janssen Products

LOCAL AND GLOBAL
WORLD-WIDE APPLICATION AND LOCAL STABILITY

Our products are in use wherever technical intelligence and experience are in demand. Our local connections are an important guarantee for this world-wide success.

We can proudly look back over 60 years of tradition as an electrical engineering company which makes us one of the best in our trade. The basis for this, in addition to the extensive technology, above all is the know-how of our employees which spans generations.

Low Voltage Switching

THE MODULAR SYSTEM – SAFE, FAST AND INTELLIGENT.

The modular system solution is oukr technically skilled reply for the safe and fast distribution of energy. Especially when the requirements for the system change due to newly connected consumers or changed motor performances. The modules can be exchanged quickly and easily without production downtimes. Our products in drawer, stick and fixed installation technology comply with both European and national standards.

The advantages of the modular system solution:

• interference arc tested (100 kA/300 ms) according to DIN EN 60439-1 suppl. 2, 1997-10
• type-tested according to DIN EN 60439-1 (120/264 kA)
• earthquake-tested according to IEC 980
• separates consistently between collective bus space/equipment space/bus distributor/cable connection space
• offers full sheet steel encapsulation
• guarantees high dissipation possibility of the resulting heat loss
• provides a high packing density (50 miniature drawers per panel)
• enables the replacement and conversion of complete levels during operation
• offers a convenient cable connection space (400 mm)
• ensures an assembly-friendly connection system from panel to panel (fishplates)
• ensures brand-independent equipping
• enables single or double front installation (Simplex/Duplex)
• supplies an intelligent network via homogeneous bus systems
