Frequently asked questions about ENCLOSED ISOLATORS
What is an enclosed isolator?
An enclosed isolator is an electrical isolation switch housed inside a protective enclosure. It is used to disconnect machinery, equipment or an electrical circuit from its power supply for maintenance, inspection or emergency isolation.
What is the difference between an isolator and a circuit breaker?
An isolator provides electrical isolation, while a circuit breaker is designed to interrupt a circuit when certain electrical faults occur. An isolator should not be described as providing fault protection unless the specific product documentation confirms this capability.
Which enclosure material should I choose?
The correct material depends on the installation environment:
- Polycarbonate and ABS for general applications
- Stainless steel for demanding or corrosion-sensitive environments
- Sheet steel for robust industrial installations
- Aluminium where a durable metal enclosure is required
Always check the product’s material grade, IP rating and environmental suitability.
Can enclosed isolators be installed outdoors?
Some enclosed isolators are suitable for outdoor installation, but this depends on the product’s IP rating, enclosure material, operating temperature and installation instructions. Check the individual product specification before installing it outdoors.
What size enclosed isolator do I need?
Selection depends on the circuit, load, current rating, number of poles, utilisation category and installation conditions. A qualified electrical professional should confirm the correct specification for the application.
What is an ATEX isolator?
An ATEX isolator is intended for specific applications involving potentially explosive atmospheres. The selected product must have the appropriate certification and suitability for the relevant hazardous-area classification. The applicable EU framework is ATEX Directive 2014/34/EU.

Tekox Terminal Strips Safety Blocks and Porcelain Blocks
Great electrical installations don't fail because of the major components. They fail because of the small ones that didn't get enough attention.
It's easy to focus on the big-ticket items during specification — and let the terminal blocks become an afterthought. But inferior connection components have a habit of making themselves known over time. Loose connections, degraded insulation, premature failure. The kind of faults that are frustrating to trace and expensive to fix.
Tekox engineer their terminal strips, safety blocks, insulated strips, and porcelain blocks to the standards your installations deserve. Available now from Demesne Electrical — get in touch and we'll show you the range.
