Joslyn Hi-Voltage TransEnd - 25 Data Sheet

SURGE PROTECTIVE DEVICES

TransEnd® – 25

MEDIUM DUTY FOR DISTRIBUTION APPLICATIONS

FEATURES AND BENEFITS

• Listed to UL 1449 4th Edition for a Type 2 SPD application.

• Protects facilities and equipment against the harmful effects of

lightning strikes and internally generated electrical transients.

• Includes pre-wired pigtail conductors to streamline installation.

• Features internal copper bus conduction path to minimize system

impedances, lowering clamping voltage and increasing protection.
