1SAM340000R1003 ABB

Manual rangers are electromechanical protection devices for the main circuit. They are mainly used to boot and stop motors manually and to provide fuse less protection against short circuits, overloads and phase failures. A minor protection of fuses saves costs, space and guarantees a quick reaction to short circuits, as it turns off the engine in milliseconds. The starter combinations are equipped with contacters. The equipment has manual control / protection against short-circuit currents and overloads, the current adjustment is adjustable for the protection of the load and the indication of magnetic shooting, has the function of disconnection, temperature compensation, remote control by means of the detachment to minimum voltage and the shooting in derivation and short-circuit rupture power (Ics) up to 100 kA.

The reference 1SAM340000R1003 specifically, is a switch for the protection of transformers, generators and systems.

Its features are:
Permanent nominal intensity Iu: 0.4A, Nominal voltage: 690V, Nominal short-circuit current in cut current Icu to 50 Hz 400 V: 100kA, Current overload release adjustment: 0.25 - 0.4 A, Instant short-circuit release adjustment range: 8A, Connection type of main current circuit circuit circuit circuit: Dry connection, Device construction:.
