LIGHTNING NDCD DC SWITCHGEAR

LIGHTNING NDCD

Following the successful launch of the Lightning DC switchgear product, we have extended the DC product range with the introduction of a DC disconnector solution for DC traction applications - the Lightning NDCD off-load disconnector.

Features

Offered in a range of current ratings, this new DC disconnector can be incorporated within the Lightning DC switchboard, or supplied loose within free-standing or wall mounting enclosure(s). Available in both 2-position (on/off) and 3-position (changeover) options, the NDCD utilises the superior technology used in the NDC circuit breaker, addressing the number of problematic factors associated with past DC isolators.

• Specifically designed for DC applications, rather than converting an existing AC isolator

• Compact design

• Can be configured either as an isolator or as a changeover switch

• Very low resistance – typically 5 µΩ for entire switch

• Ability to withstand very high short circuit currents (It has been tested up to 183kA)

• Big isolating gap

• Can be manually or motor driven, or both

• Available as component or mounted in enclosure
