Series
NTD/NTA
• Panel Mount
• Zero Voltage or Random
Turn-On Switching
• Wide Control Voltage
Range
• DC Control, AC Control
The Series NTD is available featuring
zero-voltage or random switching and a
broadened operating range (24-
280Vac). This wide range permits opti-
mum performance at both 120Vac and
240Vac line voltages.
Manufactured in Crydom’s ISO 9001
Certified facility for optimum product
performance and reliability.
