Lots: 700A automatic switch, three-pole with electromagnetic and thermal release. Rated operating currents are in the range of 250-630A. Combination circuit breaker release. Triggering currents of electromagnetic and thermal releases are regulated in the range of 250-700 A. The accuracy of the operation current adjustment is +/-15%. The tripping currents of the releases are not regulated during operation. The manual switching mechanism ensures instant closing and opening of contacts. The switching speed does not depend on the speed of movement of the handle. All sections are controlled by one handle. The handle has four positions: on/off. manually, actuation, cocking after actuation. Three arc extinguishing chambers are built into the circuit breaker. Total weight switch 17-19 kg. Designed for maximum current protection of electrical installations during overloads and short circuits in circuits with a rated voltage of up to 500 V AC, frequency 50-60 Hz, for infrequent (up to 6 times per hour) operational switching these circuits, as well as to protect electrical circuits when the voltage drops to an unacceptable value. If a short circuit occurs in the electrical circuit, the circuit breakers operate instantly. During overloads, the principle of operation of data devices is slightly different: their response time has an inverse relationship with the current strength. Series A switches are distinguished by their reliability and long service life. The machines are manufactured in climatic version - U4. AREA...
