esp415tns_su3ld_0.1

• Enhanced protection (to BS EN 62305) offering low let-through voltage further minimizing the risk of flashover creating dangerous sparking or electric shock
• Repeated protection in lightning intense environments
• The varistor based design eliminates the high follow current (/f) associated with spark gap based surge protection
• Compact space saving design
• Indicator shows when the protector requires replacement
• Remote signal contact can indicate the protector’s status through interfacing with a building management systems
• Use on three phase supplies and power distribution systems for protection against partial direct or indiect lightning strikes
• ESP 415/I/XXX versions for use with Class I or II LPS
• ESP 415/III/XXX versions for use with Class III or IV LPS; or exposed overhead three phase power lines where no LPS is fitted
• ESP 415/X/TNS versions also cover TN-C-S earthing systems
