Abstract
FIELD: transport; automatic control devices for protection of control power circuits of traction motors. SUBSTANCE: device has current limiting resistor and relay element with break output contact. Novelty in design of device is than relay element can be furnished with thermal relay whose heating element is connected to resistor of first field weakening stage, and contact is made for mechanical locking in open position. Contacts of thermal relays which control field weakening resistors of electric motor shunt circuits are connected in series. EFFECT: simplified design, improved reliability.
