AC switch-disconnectors

Telergon’ switch – disconnectors have a high operating load capacity and a high level of isolation.

With a wide current range, they consist of a sandwich-type body containing self-cleaning blade type contacts, ensuring a long-term life, and a detent mechanism that provides an independent operation.

The detent mechanism provides quick and independent switching due to the accumulation of elastic potential energy, which is transmitted at high speed to the contacts for arc extinction.

Neutral pole early make & late break

Due to the design in our 3P+N products, the neutral contact closes before the main phases and opens later, thus ensuring this operation mode.
