SPV-220
The electric drive is installed on the arrow complete with an external short circuit breaker and ensures, in extreme positions, locking of the pressed wit with an external short circuit breaker and holding the withdrawn wit with an internal short circuit
The electric mortise switch drive, type SPV-220 with internal closure, is designed for re-switching in short-term mode, locking and monitoring the position in continuous mode of centralized arrows with an undivided course of wits. The electric drive is installed on the arrow complete with an external short circuit breaker and ensures, in extreme positions, locking of the pressed wit with an external short circuit breaker and holding the withdrawn wit with an internal short circuit breaker.
The electric drive is designed to operate in temperate climates at temperatures from -45 ° to +55 ° C, relative humidity no more than 83 ± 3% at a temperature no higher than +30 ° C.
The electric drive is installed on the headset of railway switches on the right or left side of the switch and is controlled from the electric centralization post. The electric drive type SPV-220 is available with an alternating current electric motor type MCA-0.3B, 380 V.
It is allowed to use electric motors of another type, providing the necessary technical characteristics and providing control of electric drives according to approved circuit design solutions.
