Device Ratings and Specifications

DHB34 SERIES

UNITS

NOTE: Ratings are for each individual varistor element in dual assembly.

1. Average power dissipation of transients not to exceed 2.0W per varistor element (2 varistors per device).

2. 40kA capability depends on applications rated up to 115V

. 30kA applies if > 115 V

.

3. 40kA capability depends on applications rated up to 123V

. 30kA applies if > 123 V

.

4. 40kA capability depends on applications rated up to 132V

. 30kA applies if > 132 V
