Indoor switch-disconnectors compliant with EN 62271-103
Switch-disconnectors are able to shut down the rated operational current.
Depending on the preferred type of switch panel, four different types of switch-disconnectors are available. All types are also available as a disconnector/fuse combination.
M3007 switch-disconnectors (with fuses), from 24 kV to 36 kV, up to 400 A, compliant with EN 62271-1, EN 60282-1, EN 62271-105
Switch-disconnector and switch-fuse combination H22 EK, EA, SEA, from 12 kV to 38.5 kV, from 630 A to 1250 A, 16 kA, 20 kA, compliant with EN 62271-1, EN 62271-103, EN 62271-105, classes M2 (EK), M1 (EA and SEA), E1
Switch-disconnectors, switch-fuse combination H27 EK, EA, SEA, SuT, F-EK, F-EA, F-SuT, from 12 kV to 24 kV, up to 630 A, 16 kA, 20 kA, compliant with EN 62271-1, EN 62271-103, EN 62271-105, classes M1, E1
Switch-disconnectors, switch-fuse combination H29 EA, SEA, from 24 kV to 36 kV, up to 630 A, 16 kA, 20 kA, compliant with EN 62271-1, EN 62271-103, EN 62271-105
Switch-fuse combinations are used to turn medium-voltage distribution transformers in local network stations on and off. Furthermore, these protective devices have been designed to safeguard transformers from the adverse effects of internal and external faults.
These fuses have been in use for decades, and are available for almost every conceivable application. All HVHBC fuses made by DRIESCHER come with a striker pin and thermal protection and comply with EN 62271-105 for 12 to 36 kV, STA type up to 160 A or SSK type up to 125 A.
Indoor disconnectors and earthing switches compliant with EN 62271-102
Disconnector switches are able to create an isolating space, when in the open position, according to the defined requirements, however cannot switch currents.
Earthing switches are also capable of earthing parts of a circuit to all poles and can withstand the currents that occur in the event of a short circuit for a specified time. While the system is running in operating mode, these switches are de-energised.
Disconnector switches ITr, from 12 kV to 40.5 kV, up to 6,300 A, up to 80 kA, compliant with EN 62271-1, EN 62271-102, classes M1, M2.
Earthing switches ES, from 12 kV to 38.5 kV, up to 72 kA, compliant with EN 62271-1, EN 62271-102, classes M1, E1.
Indoor circuit breakers (vacuum) compliant with EN 62271-100
A circuit breaker is able to permanently conduct currents under operating conditions, as well as to activate, conduct and deactivate currents for a defined period in the electric circuit in case of a short-circuit.
The V-series is designed for the withdrawable or mobile stationary-mounted design in W-panels.
Vacuum circuit breakers in the V series for 12 kV, 25 kV, 36 kV and 38.5 kV, for 630 A, 1250 A, 1600 A, 2500 A, 20 kA, 25 kA, 31.5 kA and 40 kA (not KU-compatible), compliant with DIN EN 62271-100 and IEC 62271-1, classes C2, M2, E1 or E2, S1.
