Interrupters & STS Switches


Fault Current Limiter

The Thycon Fault Current Limiter introduces a new dimension to system protection and power quality. Unlike existing PTC and superconducting limiters, it is easy to install, requires virtually no maintenance and is low cost by nature and unlike electronic limiters or breakers, it requires no control electronics and is fail-safe. Being self-acting and self-resetting, it is suitable for remote and…


High Speed Electronic Fuse

The High Speed Electronic Fuse exhibits the same high speed features of the SSB while operating as a fast, fail-safe fuse. SSBs and HSEFs are designed for Low Voltage AC or DC applications from 0.6 to 3.0MVA. Features Silent interruption No arcing, no moving parts, no gasses or oils (no such maintenance required) Fast fault interruption time of 10 -…


Solid State Breaker

Solid State Breakers (SSB) are power electronic switches that are automatically operated to protect a load from damage caused by overload or short circuit. It is designed to detect a fault condition and immediately turn off thereby interrupting current flow to the load. Unlike a circuit breaker, which mechanically operates within 10 - 100ms (depending on conditions), the SSB is…


Static Bus Tie

Static Bus Ties (SBT) are essential for achieving highly reliable independent, stand-by, parallel or redundant supply to critical systems. Bus ties are fully automatic. Once set, they ensure that critical loads are supplied in case of supply failure or during maintenance procedures.     Applications The SBT configuration is ideal for implementing dual cord AC distribution systems or independent load…


Static Transfer Switches

Static Transfer Switches (STS) are essential for achieving highly reliable and redundant supply to critical systems. The STS provides power to items requiring a single AC supply by selecting from one of many input AC supplies. If one supply becomes unavailable the STS automatically transfers the critical load to an alternative AC supply source. Manual selection of supply is also possible. Applications STSs are suitable for back up…
