AQ M215 Motor Protection Relay

AQ M215-AQ M215 Motor Protection Relay

Sipariş No : AQ M215

AQ M215 offers a modular motor protection and control solution for larger and more important motors requiring both current and voltage based protection functions along with complete measurements of accuracy up to class 0.2S for power and energy. Up to three optional I/O or communication cards are available for more comphrehensive monitoring and control applications. Up to 12 RTD signals can be connected for thermal alarming and tripping.
