Learn more by watching our NLS 66CV520RCD | 5 Pin 20A Switched Socket Outlet | IP66 with RCD Protection video.
The NLS 66CV520RCD is a three-phase 5 pin 20A switched socket outlet rated 500V AC with a built-in 25A 2-pole RCD, designed for weatherproof industrial and outdoor power distribution. Complies with AS/NZS 3112, AS/NZS 3123, AS/NZS 3133, AS/NZS 3100, and AS/NZS 3947.3 for Australian and international industrial standards.
Industrial and outdoor applications often demand a single power point that combines switching control with earth-leakage protection to meet both safety and compliance requirements. The NLS 66CV520RCD provides integrated RCD protection (eliminating a separate circuit breaker step) and IP66 weatherproof sealing against dust and high-pressure water spray. The large cable terminals with internal wiring reduce installation complexity and the risk of loose connections on busy jobsites.
Contractors and site supervisors choose the 66CV520RCD for three-phase industrial installations because it combines safety certification with simplicity: a single lockable unit handles power distribution and earth-leakage detection without daisy-chaining components. The padlock facility on both the switch and RCD cover restricts unauthorised access and disconnection, critical on multi-trade and public sites. Impact-resistant plastic construction resists cracking and degradation under UV exposure and mechanical damage during handling.
The NLS 66CV520RCD is not suitable for indoor residential applications, electronic equipment with sensitive RCD trip curves, or frequencies outside 50/60Hz. The 25A RCD rating means the outlet is designed for general industrial circuits; circuits with nuisance tripping history require assessment by a licensed electrician.
