Page 5: Description
50-60Hz Fig. 2 The SACE Emax VF circuit breakers can be used in applications with variable frequency from 1Hz to 60Hz, with rated voltage up to 1000V. The rated impulse withstand voltage of the circuit breakers is 8kV. The SACE Emax VF switch disconnectors up to 2500A are available also in LTT version; this special version, designed for low tem- perature environment, permits to extend the operating temperature range from -40°C to +70°C. -

Page 32: Protection Releases - General Notes
WARNING: Dielectric stiffness tests must not be performed on releases, inputs or outputs. To perform impulse insulation tests (e.g. 8 Kv) on the main circuits of an Emax VF circuit-breaker, first disconnect the PR122/VF-specific connectors XK10, XK11 and XK12, by removing the actual relay as indicated in figure 21 on page 12 of this manual. -

Auxiliary power supply 11.2.2. Notes A. Use the “Belden 3105A”- type two-wire cable for instance (not supplied by ABB SACE). B. Use the “Belden 3106A”- type three-wire cable for instance (not supplied by ABB SACE). C. The unit has a “backup-protection” function; if the first command to the opening solenoid does not open immediately the circuit- breaker (TC partially fault), TRIP commands are repeatedly sent until the circuit-breaker opens (providing a Vaux is present) or the current disappears (if self-power supplied). -
