Learn more by watching our NHP NLINE NL340L | Weatherproof Isolator 3 Pole 40 amp M180 500v IP66 | Large video.
The NHP NL340L is a three-phase weatherproof isolating switch rated for 40 amperes at 500 volts, designed for surface-mounted outdoor and damp installations. The NL340L features a large handle for easy operation and is rated IP66 for high water ingress protection. Installation must be carried out by a licensed electrician and complies with AS/NZS standards for Australian switchboard work.
Outdoor switchboard installations and industrial sites require weatherproof isolating switches to safely manage three-phase power circuits in damp and weather-exposed locations. Standard indoor switches lack the IP66 protection rating needed for weather exposure, creating safety and compliance risks. The NHP NLINE range provides IP66-rated isolation switches specifically designed for these demanding environments.
Licensed electricians working on outdoor installations appreciate the NLINE range for its fit-for-purpose design and compliance-ready construction. The large padlockable handle is easy to operate even with wet or gloved hands, and the UV-resistant polycarbonate enclosure holds up through years of weather exposure without degradation. The IP66 rating eliminates the need for additional weatherproofing workarounds on damp-location switchboards.
The NHP NL340L is not rated for fully submersed, flood-prone, or continuously sprayed locations. Do not install the NL340L in environments where standing water, ice accumulation, or aggressive chemical spray exposure occurs regularly, or in locations subject to permanent immersion or saltwater submersion.

(NL340L)
Installation of the NL340L must be performed by a licensed electrician. Switchboard work is regulated under AS/NZS 3000 and requires appropriate qualifications. The NL340L also requires correct circuit protection and proper cable termination to the switchboard busbars.
Yes, the NL340L is rated IP66, which protects against water jets and high-pressure washdowns typical in wet-area electrical installations. The stainless steel fixings resist corrosion in damp environments. However, the NL340L is not designed for permanent submersion or standing water.
The NL340L is a three-pole switch rated 40 amperes at 500 volts for three-phase circuits, while the NL140L is a two-pole switch rated 40 amperes at 250 volts for single-phase circuits. Choose the NL340L for three-phase power distribution and the NL140L for single-phase applications.
The NL340L carries a one-year manufacturer's warranty covering defects in materials and workmanship. The warranty applies to both domestic and commercial installations and is void if the product is installed by unqualified persons or modified after purchase.
