Learn more by watching our NHP NLINE NL120S | Weatherproof Isolator 2 Pole 20 amp M100 250v | Small video.
The NHP NLINE NL120S is a weatherproof isolating switch rated 2 pole, 20 amp, 250V AC, with high ingress protection IP66 and a padlockable off position. The NL120S is designed for surface mounting in small enclosures and complies with requirements for outdoor electrical disconnection in wet, corrosive, or demanding environments.
Licensed electricians specify weatherproof isolators for external switchboards, meter boxes, outdoor distribution points, and any installation where moisture ingress, salt spray, or dust exposure presents a risk. The NL120S handles switchboard and sub-board isolation for single-phase circuits up to 20 amps, where manual disconnect is required ahead of MCBs, RCBOs, or other protection devices.
The NL120S fits fast into installation schedules: large isolator handle provides smooth operation without tool changes, mounting entries come with two 25-20 mm reducers already included, and stainless steel cover screws eliminate corrosion concerns on jobsites. The UV-resistant polycarbonate enclosure (RAL 7035 grey) resists fading and brittleness over years of outdoor exposure. A padlock loop on the handle allows easy lockout during maintenance, so electricians can isolate and secure the circuit without additional hardware.
The NHP NLINE NL120S is not suitable for indoor flush-wall mounting, dry interior switchboards, or non-weatherproof enclosures. It is a purpose-built external isolator and should not be retrofitted into standard interior electrical cabinets. Do not use in submerged or permanently flooded locations; IP66 protects against water jets but not submersion.

(NL120S)
The NL120S is rated 20 amp, 250V AC, for single-phase circuits. It is suitable for isolating general lighting and power sub-circuits on a 20-amp MCB or RCD protection circuit. Do not use on circuits rated above 20 amps or three-phase applications.
The NL120S is rated exclusively for weatherproof external mounting. Its IP66 enclosure is designed for outdoor, damp, and corrosive environments. Do not install flush-wall indoors; it must mount on the external surface of an enclosure or switchboard exposed to the elements.
Yes. The NL120S has an integrated lock loop on the isolator handle, compatible with standard electrical lockout padlocks and work-safe lock-off tags. You do not need separate lock-off hardware; the padlock loop is integral.
M100 is the NHP NLINE mounting format for small enclosure sizes. It indicates the mechanical footprint and entry positioning so the NL120S fits standard small weatherproof enclosures without modification. If your enclosure is M100 compatible, the NL120S will fit without adapters.
The UV-resistant RAL 7035 grey polycarbonate is rated for long-term outdoor exposure without brittleness or significant fading over 10+ years of duty. Stainless steel fasteners eliminate rust concerns. In coastal or high-UV areas, inspect annually for salt deposits or damage and clean as needed.
