|The 400 Series
installed at or within a piece of equipment such as PLCs, fire alarm monitoring systems,
security system controls, etc., will provide compact, heavy-duty surge suppression. The
units employ a sophisticated combination of brute force surge protection and impulse
filtering to prevent damage or malfunction to sensitive equipment. Reaction time is less
than one nanosecond with automatic reset after the transient has passed.
Equipment components are susceptible to damage from lightning, transients,
and surges. Conducted RFI can also be a problem. By installing the highly reliable 400
Series, transient over voltages that would normally exceed the threshold level are safely
limited. A series filter attenuates the conducted RFI.
Sine tracking virtually eliminates transients that ride on
the sine wave. The 400 Series provides superior attenuation at the critical lower
The 400 series of surge protectors meet or exceed ANSI/IEEE
C62.41-1991 and UL 1449.

- Compact size - space efficient and
easy to install.
- Maximum surge protection - large
absorption capability exceeding 400 joules.
- Fast clamp response - in less than
one nanosecond, currents are intercepted and safely diverted.
