Why the Tesla HPF120 Isolator Belongs on the Job
Safe local isolation, outdoors
Fixed equipment such as air conditioner condensers, pumps, and hot water systems needs a local isolation point so it can be safely switched off for service without returning to the switchboard. The HPF120 provides exactly that, and its IP66 rating means it stands up to dust and powerful water jets in fully exposed positions. For safe isolation, a hole is provided to padlock the lever in the OFF position — keeping equipment locked out while work is carried out.
Built to be wired quickly and survive the site
The base mount mechanism gives more wiring room and easy termination, and dual 25mm screwed conduit entries top and bottom allow four ways to surface wire the switch. Each unit ships with screwed conduit plugs and reducers for both 20mm and 25mm conduit, plus the screw caps that must be fitted to maintain the IP rating. The impact-resistant base and cover are made to survive the hardest knock in almost any installation, and insulated caps cover the base mounting screws to protect them from live cables.
Compact surface-mount footprint
At 85mm x 85mm with an overall height of 84mm, the HPF120 mounts neatly to a wall or post. Installation and connection must be carried out by a licensed electrician in accordance with Australian requirements. Tesla Electrical Components is an Australian-based brand headquartered in Wetherill Park, NSW, and this isolator is sold individually and shipped Australia-wide.
Q: Is the Tesla HPF120 suitable for outdoor use?

Q: Can the Tesla HPF120 be locked off?
Yes. A hole is provided so the lever can be padlocked in the OFF position, allowing the switch to be locked out during servicing.
Q: What conduit does the Tesla HPF120 accept?
It has dual 25mm screwed conduit entries top and bottom and is supplied with screwed plugs and reducers for connection to 20mm or 25mm conduit, along with screw caps.
