Thomas & Betts Introduces Elastimold® 38kV 25kA Current-Limiting Molded Vacuum Interrupter

mclvi.jpgThe new 38kV 25kA Current-Limiting Molded Vacuum Interrupter (MCLVI) was designed for use in wind farm towers as large as 3MVA. The unit incorporates Elastimold's proven combination of EPDM molded insulation with a current-limiting fuse and vacuum interrupter. This addition to our solid-dielectric family of switchgear utilizes a vacuum interrupter to clear low-magnitude faults in series with a Hi-Tech® current-limiting fuse to clear higher-magnitude faults, substantially reducing energy let-through. The unit includes our current sensor and internal controls. If a single current-limiting fuse clears a fault, the MVI will sense an imbalance and trip to prevent single phasing.

The small, lightweight unit is maintenance-free and environmentally friendly, containing no gas or oil, and is also available for subsurface, vault, padmount or riser-pole applications. Choose a stacked (as shown), linear or back-to-back arrangement. When used for transformer protection, the fuses can be coordinated with the vacuum interrupter so that the fuses will only operate in the event of a transformer failure.
