DynaShield® KSB LC Surge Suppression
The KSB LC series designed for use at LPZ 0A-2 or higher to protect 2 wire unbalanced analog circuits, such as 4-20 mA loops, 110 V telephone, ADSL, or ISDN applications. These SPDs offer convenient DIN rail mounted base with replaceable suppression protection modules.
- Hybrid design for LPZ 0A-2
- Slim 12 mm wide DIN rail mount
- Common mode protection
- Excellent voltage protection level
- Fast response
DynaShield Applications
ALLTEC’s Protection Pyramid depends on DynaShield® products to support its comprehensive facility framework. The second tier of protection diminishes the significance of random high-energy, short-duration electrical power transients through properly installed surge protective devices. These occurrences are typically caused by atmospheric phenomena (such as lightning strikes), utility switching, inductive loads, and internally generated overvoltages.
You can view typical installation locations in the application maps to the right by locating the numbers 5 and 6.
