Image Description


VAMP 50 Series
Protection for LV and MV feeders and motors
VAMP 50 series offers a comprehensive selection of modular protection relays for overcurrent, earth fault, voltage, frequency and line differential protection.

VAMP 50 Overcurrent and Earth Fault Protection Relay
VAMP 52 Feeder and Motor Protection Relay

VAMP 50: Low and medium voltage feeders in industrial and utility applications with optional arc flash protection and for back-up protection.

VAMP 52: Low and medium voltage feeders in industrial or utility applications with optional arc flash protection. Extensive thermal protection functions make this relay optimal for low and medium-sized asynchronous motors. In feeder configuration mode, autoreclose and directional earth fault are also available.

VAMP 55: Frequency and voltage protection for both utility and industrial applications and also for synchro check applications.

VAMP 59: Line differential protection in medium voltage systems including overhead lines and cables with optional arc flash protection. Intermediate power transformers can be applied within the protected zone.
