«à la carte»
If you're looking for a larger highly-skilled partner for the supply and assembly of medium-voltage systems (replacements or new systems), you've come to the right place.
Our project managers will work with you to define your system requirements. We'll purchase the systems for you and take overall charge of project management, coordination and testing, including medium-voltage protection technology.
Indoor switch-disconnector EN 62271-103
A switch-disconnector is able to disconnect the rated operating 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.
- M 3007 (with fuses), 24/36 kV, 400 A
- H 22, 12 up to 36 kV, 1250 A
- H 27, 12/24 kV, 630 A
- H 29, 24/36 kV, 630 A
For decades in use, available for almost every conceivable application:
HV fuse-links by DRIESCHER with pin trigger and thermal protection.
- HV fuse-link 6 up to 36 kV, Type STA up to 160 A or Type SSK up to 125 A
Indoor disconnecting switch and earthing switch EN 62271-102
A disconnecting switch is able to create an isolating distance, when in open position, according to the defined requirements (but it cannot switch currents).
An earthing switch is able to earth parts of an electric circuit for all poles and can withstand currents in case of a short-circuit for a defined period (but does not conduct current under operating conditions).
- Disconnecting switch ITr, 12 to 40.5 kV, 6300 A
- Earthing switch ES, 12/24 kV, 50 kA
Indoor circuit breaker (vacuum) 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.
- Circuit breaker V-series, 12 up to 38,5 kV, 2500 A
The Tavrida ISM type is designed for stationary installation in D-panels.
- Circuit breaker Tavrida ISM, 24 kV, 2000 A
