Thermal protection relay ZEB series

phase lossthree-phasefor electric motors

Motor protection is one of the central tasks of the electrical equipment of any machine. The electronically configurable ZEB electronic motor protection relays of the Eaton Moeller series offer the right solution for any application. The relays are UL/CSA and CCC approved and ATEX certified as protective devices for Ex-e motors, which makes them suitable for global use. • Solution for enhanced motor protection • Self-supplying electronics avoids need for connection of an external supply voltage • Adjustable tripping classes for optimum protection at varying starting conditions • Adjustable single-phasing sensitivity for symmetric and asymmetric loads • Integrated earth-fault current detection • UL/CSA and CCC approvals • ATEX certification The Z-series motor-protection relays offer reliable protection in the event of phase failures and overloads. They are suitable for the protection of EEx electronic motors and can be directly mounted on DILM contactors with up to 250 A.
