Function

Advantages

SOCOMEC fuses provide protection for low voltage distribution wiring systems. They are intended for section feeders on low voltage switchboards, high power circuits, and with network boxes and connection enclosures.

There are 2 versions of fuses: • 115 mm bar with flexible clamp. • 160 mm bar with secure clamp.

In addition to the fuses, a neutral link should be fitted to the neutral pole of the circuit breakers.

In addition to the benefits of standard gG fuses (high breaking capacity, simple and reliable discrimination, guaranteed protection over time, arc containment inside the fuse during fault elimination, etc.), these fuses have extra benefits.

Improved mechanical withstandSOCOMEC fuses can withstand a drop of one metre on any angle without breaking or bending out of shape. The impact resistance is 3 joules, as per standard HN 63-S-20. For this, the fuses have patented insulating gripping lugs and an insulating polyester casing. IP2XCIts IP2X protection index considerably enhances operator safety. Apart from the blades that project on either side of the fuse casing, the entire fuse is made of insulating material, including the gripping lugs. Once in place, this type of fuse ensures the IP2XC protection level for equipment, for example the TIPI low voltage feeder pillar

Optimum quality Product quality and traceability are ensured by an individual test and quality-control marking at the end of production.

Adapted protectionWith a slightly different curve compared to a gG fuse, a HN fuse provides better protection for low overcurrents that occur especially in case of short circuit impedance (e.g. a fault on a long section of cable). See the characteristics below.

Certified low watt loss Consumption for each rating is limited by standard HN 63-S-20, thus reducing operating costs.
