Littelfuse Startco products will be on display at MINExpo. They allow you to improve safety, increase uptime and minimise damage with the SE-330 NGR Monitor, for example. Detect low-level ground faults with the EL731 Sensitive AC/DC earth-leakage relay. Minimise catastrophic arc-flash damage by using the PGR-8800 arc-flash relay. Customize power distribution centres and mining equipment. A new product, the PGR-8800 Arc-Flash relay detects developing arc-flash incidents by looking for a combination of excess light and current. This relay acts as added insurance to minimise the harmful effects of an arc-flash incident and improve safety.
