LIGHTNING SURGE PROTECTOR FOR RTD USE

(ultra-slim)
Functions & Features
• High discharge current capacity 20 kA (8 / 20 μs), 1 kA (10 / 350 μs)
• Ultra-thin 7-mm-wide module can be mounted
in high density
• Excellent protection employing multi-stage SPD circuits
• DIN rail mounting and grounding
• Shield terminal provided
• Does not affect instrumentation signal when combined with a 3-wire RTD, thanks to the internal high accuracy series resistors
