Motor
operators
EOA500 and the latest addition EOA600 series of motor operators are intended to be used in air break switch applications in electrical distribution networks and for electrical trams and rail networks. The products are characterized by its unique design with low motor start current and high electro mechanical efficiency. The devices are designed for manual and automatic remote control of air break switches. The motor operators are simple to install and have all the necessary electronics and control panel built in.
- Unique motor mechanism with low starting current and high starting torque
- Secure self-locking motor mechanism
- Easy installation and compatible with most air break switches
- Optional automatic sectionalizing logic
- Optional lock solenoid on motor shaft for extra security
- Frame of "Marine grade" premium stainless steel
WHAT IS A MOTOR OPERATOR FORRAILWAY APPLICATIONS
The EOA600R railway motor operator, characterized by its innovative design, is a complete solution from a pole to SCADA system.
The unit is intended for control of disconnectors / earth switches with or without load break heads. The motor operator is easy to install and has built-in all functions for SCADA integration.
The motor operator can be directly applied on most 0.5 to 25 kV DC/AC single or double (AT or BT system), gang operated 3-phase disconnectors. The unit has a complete interface to SCADA system with multiple dry contacts. Optional built in 4G-LAN-Fiber RTU is available.
