Summary of Metal-Oxide Varistors (MOVs) BABB Series Datasheet
The Metal-Oxide Varistors (MOVs) BABB Series datasheet details heavy-duty transient surge suppressors from Littelfuse designed for industrial applications including motor controls and power supplies in sectors like oil-drilling, mining, and transportation. Featuring high energy absorption and a wide operating voltage range, these MOVs come in two series: BA and BB, with the BA models rated from 130V to 880VAC and the BB models rated from 1100V to 2800VAC. The varistors boast high energy absorption capacities – BA Series up to 3200J and BB Series up to 10000J.
Both series offer features such as enhanced creep and strike capability, complete electrical isolation, and rigid terminals for secure wiring. Moreover, the varistors can operate in ambient temperatures up to 85°C without derating and maintain RoHS compliance. The series differ in size and ratings; details can be found in the specifications table included within the datasheet. The varistors can withstand peak pulse currents between 50,000 to 70,000A and provide energy range protection for transients between 450 to 3200J for the BA Series and 3800 to 10000J for the BB Series.
The datasheet provides absolute maximum ratings, including the steady-state applied voltage range and transient peak pulse current capability. It emphasizes the importance of adhering to these ratings to prevent damage to the device. It also includes part numbers and specifications for individual components such as varistor voltage and clamping voltage at specified test currents.
Additionally, the document contains agency approvals like UL1449 for the BA Series and lists associated Littelfuse part numbers. The provided tables on the first two pages cover ratings and specifications in detail, outlining attributes such as maximum clamping voltage, typical capacitance, part numbers, and voltage ratings.
In conclusion, Littelfuse’s BA/BB Series MOVs are robust surge protection devices engineered for challenging industrial environments, capable of handling significant surge events, and offering solid performance over a wide temperature range. For further technical data, reference figures, and full specifications, the datasheet directs users to specific sections, tables, and diagrams.
