Fuse links to protect battery energy storage systems (BESS)

aBat fuse links are specially designed to protect battery energy storage systems (BESS).

Provide excellent protection against short-circuits for the batteries as well as other devices of the installation such as contactors, switches, etc.

Thanks to the design of their melting elements, the materials employed and their construction with solidified sand, these fuse links provide excellent characteristics:

· Ultra-fast acting.
· Very good current limiting.
· Very low I²t values.
· High breaking capacity.
· Excellent cycling capability.

aBat NH 1500V DC fuse links range comprise size NH3L with rated currents between 450A to 1250A, with rated voltage of 1500V DC. The rated breaking capacity is 120kA.

These fuse links have a striker that can be used as a visual indication or can be
equipped with a microswitch mounted on the fuse link.
