EN
TECHNICAL SPECIFICATIONS
Insulation: Class2, Double insulation.
Overvoltage category: CATIV 600V
Note:
These meters meet CAT III and CAT IV IEC 61010 standards. The IEC 61010 safety standard
denes four overvoltage categories (CAT I to IV) based on the magnitude of danger from transient
impulses. CAT III meters are designed to protect against transients in xed-equipment installations
at the distribution level; CAT IV meters are designed to protect against transients from the primary
supply level (overhead or underground utility service).
