Our 200A–1000A Isolators & Switch Disconnectors collection covers heavy‑duty electrical isolation for higher current applications. Designed for safe and reliable circuit disconnection, these isolators are suited to commercial, industrial and larger residential installations where control and clear isolation of power is essential.

This range includes high‑current isolators and switch disconnectors from 200 amp through to 1000 amp ratings. They are typically used by trade electricians, industrial installers and facilities teams who need dependable main isolators for distribution boards, plant and fixed equipment. Suitable for both new installations and maintenance work where robust isolation is required.

Common use cases include isolating supplies to industrial machinery, large HVAC systems, commercial kitchens, workshops, warehouses and sub‑main distribution. These switch disconnectors are also used in plant rooms and electrical cupboards where a clear on/off position and safe manual operation are needed during servicing or emergency shutdowns.

When choosing a 200A–1000A isolator, consider the required current rating, number of poles, and whether the application calls for load break capability. Mounting style and enclosure type are also important, particularly where space, environment or access needs to be managed. Always ensure the isolator matches the system design and site requirements.
