IEC Safety Contactors

Safety contactors provide a safe and reliable way to control electrical power in industrial and commercial applications. WEG Electric CWBS series IEC safety contactors comply with IEC and UL standards, featuring mechanically linked contacts and mirror contacts to ensure safety circuits for machines and equipment operate according to international safety standards.

Mechanically-linked contacts ensure that the normally open and normally closed auxiliary contacts cannot be simultaneously closed.

• When a normally open auxiliary contact is closed, none of the normally closed auxiliary contacts may be closed
• When a normally closed auxiliary contact is closed, none of the normally open auxiliary contacts may be closed

Mirror contacts are normally closed auxiliary contacts mechanically linked to the main power contacts of the safety contactor. Since the mirror contacts can never be closed simultaneously with the main contacts, they provide a way for safety circuits to reliably monitor the status of the main contacts.
