Telergon - Model Series CEC - AC Changeover Switches
Telergon manufactures the highly reliable AC changeover switches, a critical component in electrical systems ensuring uninterrupted power switching and safety. These switches, available under series CCF, CCP, S5F, and S5B, are constructed using high-grade, self-extinguishing materials providing excellent electrical insulation, low smoke emission, and robustness against electromechanical stress. Featuring a sophisticated detent mechanism, these switches ensure quick, independent switching by utilizing stored elastic potential energy that rapidly drives contacts apart, effectively extinguishing the arc. Additionally, the 3P+N design incorporates early make and late break for the neutral pole, ensuring the neutral contact closes before and opens after the main phases for enhanced operational safety and reliability. Ideal for environments requiring stringent safety and performance standards, these switches are vital in modern electrical installations.
Changeover switches on-load Series CEC, available from 63A up to 125A for 3P or 3P + N versions. Compact design, common output internally bridged, long electrical and mechanical life even in extreme conditions (tropical and polar) and in industrial environments, lower energy losses. Protection against accidental overvoltage when making/breaking in equipment connected between phase and neutral (our standard 3P + N) with neutral pole early make & late break.Standard operated with manual handle on the right, also available with manual handle on the left.
