Distribution Arresters

Distribution Arresters mainly include Zforce ZNP Arresters, Zforce ZHP Arresters, Zforce ZRP Arresters, ZE 5kA Deadfront Elbow Arresters (8132 Series), Zforce Ordering Information & Accessories, etc.

Distribution Arresters types, features, performance and other details:
Zforce Arresters features:
Zforce Arresters have mold-on polymer housing for the ultimate seal against moisture ingress
High strength Fiberglass for high fault-withstand design
Integrated Ground Lead Disconnet for fast, reliable operation. Operates in less than 2 seconds at 1 amp and less than 2 cycles at 1,000 amps
The Zforce Arresters designs are tested in accordance with the latest ANSI/IEEE standards for metal oxide arresters.

Zforce Arresters Notes:
Reduce creepage by 1.45 inches (36.8mm) when ordering without insulating bracket.
Weight does not include metal mounting hardware
MCOV = Maximum Continuous Operating Voltage that may be applied continuously between the terminal of the arrester.
The equivalent Front-of-Wave is the maximum discharge voltage for a 5kA impulse current wave which produces a voltage wave cresting in 0.5 μs.
Based on switching surge current imulse of 45x90 μs, 500 amperes.

In addition to Zforce ZNP Arresters, Zforce ZHP Arresters, Zforce ZRP Arresters, ZE 5kA Deadfront Elbow Arresters (8132 Series) and Zforce Ordering Information & Accessories also can be provided.
