Низковольтное оборудование
Low-voltage equipment for distribution, protection and control of electrical circuits up to 1000V. Circuit breakers, contactors, relays, fuses and protection devices.
How to choose low-voltage equipment
When selecting LV equipment, consider: rated current, load type (resistive, inductive, capacitive), operating conditions (temperature, humidity, vibration) and enclosure protection rating (IP). For industrial facilities, equipment with enhanced breaking capacity (Icu from 25 kA) is recommended.
Main types
- Circuit breakers — overload and short-circuit protection (modular up to 125A, power up to 6300A)
- RCBOs/RCDs — residual current protection
- Contactors — power circuit control (9A to 800A)
- Relays — network parameter monitoring
- Fuses — fast-acting protection (blade, cylindrical)
