www.mpe.co.uk LEMP/NEMP protection units designed for application within zoned electrical distribution systems fully protected against the effects of transients. Units will contribute to protection of susceptible equipments from external natural and artificial EMP threats. The product is a two-chamber single cabinet integrating high speed high energy lightning overvoltage surge arrestors with screw terminal connections to accept the field wiring electrical cable distribution system. The unit will tolerate multiple events and is self restoring post LEMP. The cabinet is rugged and corrosion resistant designed for chassis or bulkhead mounting. GENERAL TECHNICAL SPECIFICATION Rated voltage 250VAC 50/60Hz line to earth Rated current 100Amp Operating temperature range -45 o o C to +85 o C Storage temperature -55 C to +100 o C Current overload rating 10x rated current for 1 second 1.5x rated current for 15 minutes Voltage overload rating 1.1x rated voltage continuously RATINGS Product Primary Surge Arrestor Ratings Equipment Protection Part Number Number Lines Operating Voltage Peak Surge 8/20µs Current Maximum 2ms Energy Absorption Surge Transmission Impressed 8/20µs Current LP46000 2 LP46001 4 25kA 400J @200A LP46002 2 LP46003 4 40kA 600J @300A LP46004 2 LP46005 4 70kA 1000J @500A LP46006 2 LP46007 4 320VAC 850V 100kA 1600J @800A
