Protect sensitive elevator circuit components and comply with recent National Electrical Code® (NEC) changes with Mersen’s integral surge protection. Mersen now offers its Type 1 surge protection as an integral option in its Fusible Shunt Trip Switch, also commonly referred to as an elevator switch.

Results from a recent NFPA survey showed that 24% of respondents report damage to elevator circuits due to voltage surges. In response to this, the 2017 NEC has been changed to require surge protection in applications where an elevator is designated as an emergency load.

Please see Mersen’s new brochure, “2017 National Electrical Code: Changes in Overcurrent and Surge Protection,” for a comprehensive list of code updates for 2017.
