Switch disconnectors
Switch disconnectors are devices that meet the insulation requirements of the standard IEC
60947‑3 and IEC 60947-2 CBI-Y Annex L.
The switch disconnector has an identical design to the circuit breaker and has the same
dimensions, weights, and optional accessories. However, it di󹪜ers from the circuit breaker in
that it does not have any protection functions and therefore no electronic trip unit (ETU) and
no internal electronics or current transformer.
The disconnector ensures an insulation clearance between its main contacts in the open
state that isolates all downstream parts of the installation.
