슈나이더 EZ7SW-3P100A 절연 스위치

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 배전 시스템.

핵심 기능:

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).

전원 스위칭: Used for connection control between the power supply side and the load side.

응용 시나리오

산업용 배전 시스템

– Main power switch for equipment, facilitating safe isolation during maintenance and overhaul.

– Isolation protection for motor control circuits.

Commercial Building Power Distribution

– Main switch for floor distribution boxes.

– Group control for lighting systems.

주거용 배전

– Main incoming switch for villas or multi-storey residences.

– Dedicated isolation for large electrical appliances (such as air conditioners and water heaters).

임시 전원 공급 장치 시나리오

– Power control for construction site distribution boxes and mobile equipment.

Differences from Circuit Breakers

Key Differences Between EZ7SW (Isolating Switch) and EZ7 Circuit Breaker:

특징	EZ7SW Isolating Switch	EZ7 Circuit Breaker (예를 들어, EZ7-100A)
보호 기능	No overload/short-circuit protection	With dual protection against overload and short-circuit
Arc Extinguishing Capacity	Limited, suitable for normal load operation	Strong, capable of breaking short-circuit current (6그만큼)
지원 위치	Power supply side, used for isolation	Load side, used for protection and control
작동 빈도	낮은 (1,700 mechanical life cycles)	높은 (10,000 mechanical life cycles)

선택 제안: 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.

Installation and Usage Guidelines

설치 요구 사항:

– 수직으로 설치 (경사 ≤ 5°), with the operating handle in the upward position for closing.

– Install using standard DIN rails for easy replacement and expansion.

– Ensure the installation location has good ventilation, with an ambient temperature of -5℃ ~ +55℃.

배선사양:

– 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.

사용시 주의사항:

Breaking with fault is strictly prohibited: Operate only when the load is working normally.

– 유지보수 전, the circuit breaker must be disconnected first, then the isolating switch.

– Ensure hands are dry during operation to avoid electric shock risks.

요약

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 “최후의 방어선” 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 (예를 들어, EZ7-100A) to build a complete power distribution solution of “격리 + 보호”
