The HENGSTLER RY mains isolation relay is predominantly used in appliances for which two-pole disconnection is prescribed. The two contacts in this relay open by a defined amount of > 3 mm. The creepage and clearance distances between the contacts and the drive system are > 8 mm. The RY mains isolation relay can be supplied with either a DC or an AC monostable drive system.
