Schneider EZ7SW-3P100A is an isolating switch with 3 poles and a rated current of 100A. It belongs to Schneider’s Easy 7 series of low-voltage terminal power distribution products and is mainly used in industrial and commercial системы распределения электроэнергии.
Основные функции:
Circuit Isolation: Provides obvious electrical isolation during maintenance or overhaul to ensure personnel safety.
On/off Operation with Load: Can connect and disconnect load circuits below the rated current (it does not have overload and short-circuit protection functions).
Power Switching: Used for connection control between the power supply side and the load side.

Differences from Circuit Breakers
Key Differences Between EZ7SW (Isolating Switch) and EZ7 Circuit Breaker:
| Особенность | EZ7SW Isolating Switch | EZ7 Circuit Breaker (например, EZ7-100A) |
| Функция защиты | No overload/short-circuit protection | With dual protection against overload and short-circuit |
| Arc Extinguishing Capacity | Limited, suitable for normal load operation | Сильный, capable of breaking short-circuit current (6тот) |
| Позиция приложения | Power supply side, used for isolation | Load side, used for protection and control |
| Частота работы | Низкий (1,700 mechanical life cycles) | Высокий (10,000 mechanical life cycles) |
Предложение по выбору: They are usually used in conjunction. The circuit breaker is responsible for protection, and the isolating switch is responsible for isolation to ensure maintenance safety.
Рекомендации по установке и использованию
- Требования к установке:
– Install vertically (наклон ≤ 5°), with the operating handle in the upward position for closing.
– Install using standard DIN rails for easy replacement and expansion.
– Обеспечьте хорошую вентиляцию места установки., with an ambient temperature of -5℃ ~ +55℃.
- Характеристики проводки:
– Connect the power supply to the static contacts (upper end) and the load to the moving contacts (lower end).
– Tighten with a torque of 3.5Nm (using M7 screws) to ensure good contact.
– The cross-sectional area of the wire should be ≤ 150mm² to ensure a secure connection.
- Меры предосторожности при использовании:
Breaking with fault is strictly prohibited: Operate only when the load is working normally.
– Перед техническим обслуживанием, the circuit breaker must be disconnected first, then the isolating switch.
– Ensure hands are dry during operation to avoid electric shock risks.
Краткое содержание
Schneider EZ7SW-3P100A is a reliable industrial-grade isolating switch, specifically designed for 380V three-phase power distribution systems, providing safe isolation and load-carrying operation functions. Although it does not have protection functions, it serves as the “последняя линия защиты” for electrical safety and is crucial in maintenance and overhaul processes.
Purchase Tip: If complete protection functions are required, it is recommended to use it with Schneider’s EZ7 series circuit breakers (например, EZ7-100A) to build a complete power distribution solution of “изоляция + защита”
