Description
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.
To ensure that our relays as used in your applications carry on doing their job reliably for years, the quality of products bearing the HENGSTLER name is the highest priority. All our locations are certified to ISO 9001 and ISO 14001, and the entire product range is, as you would expect, in conformity with RoHS and REACH regulations.
Isolating high switching loads is a tough challenge that has been around as long as there have been relays. If, on top of that, there are normative requirements for creepage and clearance distances, only a manufacturer with many years’ experience in the development and manufacturing of relays can help. This experience is incorporated in HENGSTLER mains isolation relays, to ensure electrical safety for people and machines.
