Tesla TWIS3P63L 3 Pole Weatherproof Isolator Switch 63A 415V M160 Surface Mount

Description

High-capacity three-phase weatherproof isolation, 63A rated.

The Tesla TWIS3P63L is a three pole (three phase) weatherproof isolator switch rated 63A, carrying an M160 motor rating that lets it switch three-phase motor loads up to 40A. As the highest three-phase current rating in the Tesla TWIS large range, it is built for surface mounting in any external application, with a padlockable OFF position, fixed earth and neutral connector bars, and an impact-resistant enclosure.

Why the Tesla TWIS3P63L Isolator Earns Its Place

Three-phase isolation at the top of the range
A three pole isolator switches all three phases together, giving complete local isolation of three-phase fixed equipment. Rated 63A, the TWIS3P63L is the highest three-phase current rating in the Tesla TWIS large range, suited to heavier circuits and larger plant. Its M160 motor rating adds another dimension: the M rating divided by four gives the motor current it can handle — 160 ÷ 4 = 40A — so it comfortably switches three-phase motor loads such as air conditioning plant, pumps, compressors, and machinery, backed by AC22A and AC23A utilisation categories for switching mixed resistive and motor loads.

Made for fast, tidy termination
The base mount mechanism gives generous wiring room and easy termination, with fixed earth and neutral connector bars using dual clamping screws per tunnel for secure connections. Dual 25mm screwed conduit entries top and bottom allow four ways to surface wire the switch, and each unit ships with screwed plugs and reducers for 20mm or 25mm conduit plus the screw caps that must be installed to maintain the IP rating. A mounting template is included to speed up installation.

Weatherproof and built to last
Rated IP66, the TWIS3P63L stands up to dust and powerful water jets in fully exposed positions. The impact-resistant base and cover survive the hardest knocks in almost any installation, and a hole is provided to padlock the lever in the OFF position for safe lockout during servicing. It is backed by a 10 year warranty. 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: What motor load can the Tesla TWIS3P63L handle?
Although nominally rated 63A, its M160 motor rating gives a three-phase motor current capacity of 40A (160 divided by 4), suiting motor loads such as air conditioning plant, pumps, and compressors.

Q: Is the Tesla TWIS3P63L suitable for outdoor use?
Yes. It is rated IP66 and weather protected for any external application. The supplied screw caps must be installed to maintain the IP rating.

Q: Can the Tesla TWIS3P63L be locked off?
Yes. A 6mm hole is provided so the lever can be padlocked in the OFF position for lockout during servicing.
