Datasheet Class 1 Division 2 Certified MRS/MRZ Relays with Secured Levers Two series of Class 1 Division 2 MRS/MRZ relays are available: one with spring clips securing the retaining levers and recently released versions with the levers secured with adhesive. NEW Securing the lever means the relay is no longer socket mounted but it does allow access to the marking tag holder on the lever (the spring clip versions make use of the tag holder so a marking tag cannot be used). These relays have higher immunity to vibration. All electrical specifications remain the same as the spring clip versions and the non-Class 1 Division 2 versions. ZQV jumpers can still be used and the modules still require just 6.1mm of DIN rail. The CSA rating is groups A, B, C and D, temperature code T6.
