FAQ
-
What is a modular isolator used for?
An isolator provides on-load or off-load disconnection of a circuit for maintenance and safety — it does not provide overload or short-circuit protection like an MCB, so it's typically used alongside protective devices, not instead of them.
-
How many poles do I need?
This is a 3-pole, 40A unit. Match the pole count to what you need to isolate — a three-phase supply.
-
Can I install this myself?
No — isolators are installed inside a distribution board and connected to live busbars, and must be fitted by a licensed electrician.
-
Is this the same as a main switch?
It's often used as one — a modular isolator of this type is commonly fitted as the main incomer disconnect on a distribution board, or to isolate a sub-circuit for safe maintenance.
