Intelligent into the future
EFEN’s core competences include the NH fuse-switches for safe energy distribution. The E3 and E4 NH fuse-switches offer outstanding electrical values and a wide range of upgrade options for smart energy distribution. Ideal for use in local network stations, cable distribution cabinets and in low-voltage distribution boards in industry and infrastructure.
E4 NH fuse-switches and fuse strips
With the E4 series of NH fuse-switches and fuse strips, EFEN offers a standardised range of devices for power distribution, which provide the basic requirements for a smart power distribution network.
- Parallel switching splits the resulting arc and increases the service life of the system
- The new overlapping protection offers users greater safety
- With an installation depth of 175 mm, the E4 is the flattest safety edge on the market
- Low-voltage current transformers Low-voltage current transformers can be retrofitted by simply swinging them into place on the back of the safety edge
- Record and transmit energy data using the easy-to-snap-on measured value acquisition module (MEM 1)
E3 NH fuse-switches
- The E3 NH fuse-switches offer outstanding electrical values
- For example, the E3-High-Performance version with
120 kA short-circuit resistance - 3-pole switchable versions for 60 and 100 mm busbars.
- 1 and 3-pole switchable versions in sizes 00 and 1 to 3
- The extensive range of accessories offers a variety of upgrade options for intelligent power distribution
- The easy installation of the E3 NH fuse-switches sets special standards, whether for installation or connection
NH fuse-switches
As a specialist in safety interfaces, EFEN offers a proven range of fuse-switches and fuse strips for power distribution in different series with many options and application-specific variants.
- NTSL NH fuse-switches, size 3, single-pole switchable, with a rated power of 630 kVA at AC 400 V
- EKDEO NH fuse-switches, size 2, 1-pole switchable
- EDURO fuse-switch disconnectors size 00 to 3
- NH fuse-switches size 4a, single-pole switchable
Pre-assembled NH fuse-switches ready for connection
Changes in energy distribution increasingly require the provision of measured values for energy management systems. EFEN made pre-assembled NH fuse-switches from the E³ series with current transformers (xxxA/1A) and small signal transformers (xxxA/333mV) that offer convenient solutions for this.
The devices are completely designed for installation in cable distribution cabinets or local network stations. The measured values can be easily integrated into the data networks via an interface, hard-wired to a connection module with RJ12 socket, RJ12 connection cable or Phoenix plug. The installation dimensions of the switching devices are not changed, so there is no need for complex modification of the systems.
The pre-assembled E³ NH fuse-switches offer you the following advantages:
- Complete and tested installation set, nothing can be forgotten, no wiring errors.
- Firmly defined transformation ratios, simple integration into the management systems.
- Quick and easy installation thanks to pre-assembled transformers and ready-to-connect terminal connection.
- Connection with commercially available measuring modules via RJ12 plug or RJ12 connection module.
