After a fault occurs, use an MB or MR before reclosing for inexpensive, efficient fault location.
The MB is line-powered and battery free.
The built-in reset button in the MB model eliminates the need for a separate reset tool.
MB models are only for underground applications.
SEL fault indicators have more than 50 years of field-proven reliability.
