Portable Switch Kit

A revolution in the safe and efficient temporary isolation of MV Networks

Especially designed for quick-and-easy installation and removal, Siemens portable switch kit provides a source of temporary isolation at non-designated switching locations.

The electrical switching operation is performed with a special version of the Siemens Fusesaver® vacuum circuit breaker. Three units are pre-configured into a 3-phase ganged switching kit with wireless connection between phases enabling synchronous opening and closing of the circuit.

An operator can trigger this function using a live line stick and has 60s to clear the area before the Portable Switch Units operate. Once the electrical switching has been completed the circuit can be isolated though the removal of a temporary bridge in series with the switch unit.

The Portable Switch kit provides a number of key features and safety benefits to line crews over traditional solutions to temporary isolation, including:

Reliable Synchronous Switching

The Portable Switch kit provides a reliable three phase ganged switching operation using the wireless radio connecting each phase in the kit.

Load Break and Pick-up Capability

The Portable Switch kit uses the proven vacuum circuit breaker of the Fusesaver® to perform switching duty.

Rugged Carry Case

Portable Switches are supplied packaged in a ruggedised outdoor case which is suitable for transport on service vehicles.

Fast and Simple Installation

Siemens range of mounting designs provide flexibility and ease of installation. Choose from an in-line tension mount, a line hung mount or a cross-arm mount.
