IEC 60255-27 Measuring Relays and Protection Equipment - Part 27: Product Safety Requirements

This part of the IEC 60255 series describes the product safety requirements for measuring relays and protection equipment having a rated a.c. voltage up to 1000 V with a rated frequency up to 65 Hz, or a rated d.c. voltage up to 1500 V. Above these limits, IEC 60664-1 is applicable for the determination of clearance, creepage distance and withstand test voltage.

This standard details essential safety requirements to minimize the risk of fire and hazards caused by electric shock or injury to the user.

The object of this standard is to have a comprehensive standard that covers all aspects of product safety and the related type and routine tests, for measuring relays and protection equipment.
