The circuit-breakers can be installed vertically or horizontally. 4 types of interlocks are available: type A: between 2 circuit-breakers (power supply + emergency) B2342 Model Scale Apparatus Emax VF 1SDH000909R0001 Doc. no. Page No 30/66...
- the auxiliary contacts For the change over, the customer can use a suitable electronic relay, whose diagram is supplied by ABB SACE. The mechanical interlocks between two or three circuit-breakers are made by means of cables that can be used for circuit-breakers installed, either side-by-side or one over the other.
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).
The PR122/VF is a high-performance protection unit offering Protection, Measurement, Data storage, Communication (optional), Self-test and Load control functions for ABB SACE ‘Emax’ low-voltage air circuit-breakers, for application at variable frequency. The PR122/VF unit installed on CB is connected to current sensor resistor for reading of primary current signals, and to Trip Coil for the management of CB Opening commands.
