This is a document about eVM1 installation and service instructions, which introduces the features and characteristics of the products.
This manual provides the information required to install, commission, and maintain the ABB eVM1 medium‑voltage withdrawable circuit‑breaker. It includes safety warnings, environmental protection guidelines, and detailed procedures for handling, packing, and storage. Qualified personnel must follow the instructions to ensure safe operation and compliance with relevant standards.
The document is organized into sections covering the product description, structure, operation, circuit‑breaker characteristics, installation steps, putting‑into‑service procedures, maintenance tasks, X‑ray emission standards, spare parts, and the multifunction protection and switchgear control unit. Additional appendices contain wiring diagrams, testing procedures, and contact information for ABB support.
| Rated voltage | 12…17.5 kV |
|---|---|
| Rated current | 630…1250 A |
| Short‑circuit rating | 16…31.5 kA |
| Maximum ambient temperature | +40 °C |
| Storage temperature range | –5 °C to +45 °C |
Before any handling, ensure the capacitors are discharged, the apparatus is in the open position, and use a special lifting tool with safety hooks to avoid stressing insulating parts.
If storage is required, keep the unit in a dry, well‑ventilated environment with temperatures between –5 °C and +45 °C.
After cutting the auxiliary supply, the capacitor is discharged by the IED power consumption; the red LED on the CFD device turns off when discharge is complete.
