The 25A, 4-Pole Rotary Isolator is designed to provide complete disconnection of all live conductors, including the neutral line, in a single rotary action. This makes it an essential component for controlling and maintaining industrial machinery, commercial HVAC units, compressors, and ventilation systems. Its 25-amp current rating offers a higher capacity than 20A variants, making it suitable for more demanding loads while still fitting standard 25-body enclosures.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eDurability is a key feature of this isolator, boasting an IP65 ingress protection rating. This means it is completely dust-tight and protected against low-pressure water jets from any direction. Such rugged construction allows for safe installation in workshops, outdoor plant rooms, or manufacturing floors where dust and moisture are present. The clear rotary switch mechanism provides tactile and visual confirmation of the \"On\" and \"Off\" states, giving technicians and operators the confidence that power is truly isolated before maintenance begins.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eWhy Choose This Rotary Isolator\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eChoosing the 25A 4-pole rotary isolator ensures you have a safety device that matches the power requirements of medium-duty three-phase equipment. Its ability to switch all three phases and neutral simultaneously eliminates the risk of a floating neutral, enhancing overall system safety. The IP65 rating means fewer environmental concerns, while the robust 25A rating provides headroom for continuous operation without overheating. For electricians and facility managers, this isolator offers a straightforward, code-compliant solution for local isolation needs.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eKEY FEATURES\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eComplete 4-Pole Isolation:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Switches three phases and neutral together for total circuit disconnection.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eIP65 Protection Rating:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Dust-tight and resistant to water jets; ideal for indoor or outdoor use.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003e25A AC Rating:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Handles continuous loads up to 25 amps, suitable for larger motors and HVAC units.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eClear Rotary Action:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Provides distinct tactile feedback and visual status indication.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003e415V AC Compatibility:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Designed for standard three-phase commercial and industrial systems.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eDurable Construction:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Built to withstand harsh environments without performance degradation.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eTechnical Specifications\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eModel Number:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e RI25\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eCurrent Rating:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 25 Amps (AC)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eNumber of Poles:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 4 (3 Phase + Neutral)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eVoltage Rating:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 415V AC\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eIngress Protection:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e IP65\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eBody Size:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 25 Body\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eMounting Type:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Surface mount (typical)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eEnvironmental Use:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Indoor and outdoor (non-submersible)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eCertification Compliance:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Industrial AC isolation standards\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eFrequently Asked Questions (FAQs)\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003e1.
