Product information

These heavy-duty suppression circuits are UL recognized Type 1ca (UL 1449th edition) and offer a convenient DIN rail mounted base with replaceable suppression protection modules.

For maximum safety, it relies on fast-acting, high-energy dissipating thermally protected metal oxide varistors and employ arc quenching technology for maximum safety. A visual status window is included to monitor the AD-AC ‘s operation.

DynaShield® AD-AC Series: Single Pole Surge Suppression

Versatile application enhances electrical/ electronic equipment load reliability by:

Lowering equipment maintenance costs

Reducing operational downtime

Preventing lightning induced hardware failures

Increases return on investment (ROI) by:

Extending equipment life expectancy

Lowering the number of insurance claims

Extending Equipment Mean Time Between Failure (MTBF)

Eliminating costs associated with service calls

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.
