EKF Connecting Plates Kit VA-99M 800 - Durable Plastic - Black

There are seven sizes of circuit breakers in the range. Each size has its own accessories. Accessories for VA-99M with thermal magnetic release include: Emergency contact, Additional and emergency contacts, Undervoltage release, Independent release, Output extensions, Manual rotary drive, Electric drive, Mechanical interlock. Installation method: Additional releases and contacts are installed in sockets in the breaker housing located under the false panel. Conductors from them are laid in the side grooves of the housing after moving the false panels upward. Assembly is performed in reverse order. For VA-99M with electronic release, emergency and additional contacts are available. Application: - Independent release EKF: Designed for remote disconnection of the circuit breaker. It is an electromagnet that acts on the "release" mechanism causing breaker disconnection when voltage is applied from an external source. After remote disconnection, the breaker is switched on manually or remotely via electric drive. - Undervoltage release EKF: Disconnects breaker when input voltage drops to 70% of nominal and prevents switching on if voltage is below 85% of nominal. Used to disconnect equipment under unacceptable voltage. Can also be used as independent release with a push-button switch in control circuit. - Additional contacts EKF: Signal the position of power contacts. - Emergency contacts EKF: Signal breaker tripping due to overcurrent, independent release, undervoltage release, or 'TEST' button. Signal is switched off when breaker returns to initial state. - Additional + emergency contacts EKF: Combined signaling of power contacts position and breaker tripping. - Manual rotary drive EKF: Converts rotational movement to translational for breaker operation. Mounted directly on breaker; handle on device door operates breaker through door. - Motor drive VA-99M EKF: Designed for switching circuit breakers on/off. The mechanism automatically charges the spring system. Energy stored during breaker off operation is used to switch it on. - Mechanical interlock for two VA-99M EKF: Prevents simultaneous switching on of two breakers in manual reserve input schemes.
