Eaton, SD Surge Suppressor Unit 22 V ac, 32 V dc Maximum Voltage Rating 20kA Maximum Surge Current Surge Protection

10. Eaton MTL Ultra Slim Loop Surge Protector - SD Series. The SD series of surge protector units from Eaton has an ultra-slim design for protecting electrical equipment against surges on control loop cabling. The SD surge protection devices use a hybrid protection circuit, combining sold state electronics and a gas-filled discharge tube (GDT). This combination is designed for exceptionally low line resistance and adds only a small voltage drop to the system whilst providing surge protection up to 20kA. Features and Benefits. Protection for 4-20mA loops Multi-stage hybrid protection circuit up to 20kA maximum surge current Range of voltage ratings to suit all process I/O applications Designed for high bandwidth or low resistance applications Auto reset Optional loop disconnect ATEX Certified
