The Suntree SISO-63 is a 4-pole enclosed AC isolator (switch-disconnector) rated 63A at 400V AC for on-load isolation in solar PV and three-phase distribution systems. Its IP66 weatherproof enclosure, moulded in PC/ABS, suits indoor and outdoor installation in demanding conditions. The rotary mechanism uses a double-break contact design with silver-alloy rivets for dependable switching, and the handle is padlockable in the OFF position for lock-out/tag-out during maintenance, with a high-visibility red/yellow handle indicating switch status. Conforming to IEC/EN 60947-3 and operating across -25 to +85 degC, it provides complete circuit isolation for inverters, sub-distribution boards and motor circuits where a robust, weatherproof four-pole disconnect is required.
