UL 497A

UL 497A addresses secondary protectors for use in single or multiple pair-type

communication circuits intended to be installed in accordance with Article 800 of the

National Electric Code and to have an operating voltage of less than 150 V rms with respect

to Ground. The purpose of UL 497A is to help reduce the risk of fire, electric shock, or injury

resulting from the deployment and use of these protectors. UL 497A requirements do not

cover telephone equipment or key systems.
