Description 20A 4 Pole AC Isolator Switch IP66 – Heavy Duty Rotary Disconnect The Narain Solar 20A 4 Pole AC Isolator Switch is a professional-grade rotary disconnect switch designed for safe and reliable isolation of three-phase AC circuits. Built within a durable IP66 rated enclosure, this 20A 4 Pole AC Isolator is suitable for both indoor and outdoor electrical installations where environmental protection is required. This model is ideal for smaller three-phase systems, light commercial solar PV installations, and control panels requiring secure AC isolation. Designed for Safe Three-Phase Isolation The 4 pole configuration (3 Phase Neutral) ensures complete disconnection of all live conductors during maintenance or emergency shutdown procedures. The clearly marked ON and OFF positions provide visual confirmation of switch status, improving installer and maintenance safety. This 20A 4 Pole AC Isolator is commonly installed between: Solar inverter AC outputs Three-phase distribution boards Commercial electrical panels Small industrial machinery HVAC systems Its compact design makes it ideal where space is limited but safe isolation remains essential. IP66 Weatherproof Protection With a certified IP66 rating, this AC isolator is protected against: Dust ingress Heavy rain Water jets Outdoor environmental exposure This makes it suitable for external wall mounting near solar inverters, plant rooms, and industrial environments. The high-impact thermoplastic enclosure ensures long service life even in demanding UK weather conditions. Professional Installation Benefits The rotary handle mechanism delivers smooth switching action while maintaining strong contact pressure internally. The handle is lockable in the OFF position, allowing compliance with electrical safety procedures during maintenance.
