Haivo RH-A series outdoor distribution disconnect switches are purpose-built for no-load switching operations in 15kV, 27kV and 38kV medium voltage power distribution networks. As essential safety devices, they ensure complete electrical de-energization of circuits, creating a visible break that protects maintenance personnel and equipment from accidental energization. With rated currents ranging from 200A to 630A, these robust isolators serve as the primary safety isolation point for utility substations, industrial facilities, renewable energy installations and large commercial properties worldwide.
Engineered to withstand harsh outdoor conditions, our disconnect switches deliver reliable performance across extreme temperature ranges and environmental challenges. They support both manual and motorized operation modes and can be seamlessly integrated with earthing switches to provide comprehensive grounding protection for isolated circuit sections.
Reliable No-Load Isolation: Designed exclusively for off-load operation in compliance with IEC 62271-102 standards, providing absolute electrical separation for safe maintenance procedures
Broad Voltage Compatibility: Covers 15kV, 27kV and 38kV medium voltage levels, allowing standardization across multiple distribution system configurations
Superior Insulation Performance: 95kV-170kV BIL (Basic Insulation Level) ratings effectively withstand lightning surges and switching overvoltages
Weather-Resistant Construction: High-strength silicone rubber insulators offer excellent UV resistance, corrosion protection and thermal stability from -40°C to +70°C
Flexible Operation Options: Available in both manual and motor-operated versions to suit different site requirements and automation levels
Earthing Switch Compatible: Pre-engineered for easy integration with earthing switches, enabling safe grounding of isolated circuits

Every RH-A series disconnect switch is designed and manufactured in strict accordance with international IEC 62271-102 standards and undergoes rigorous quality testing before shipment.
Our commitment to quality is backed by a comprehensive 2-year warranty covering all manufacturing defects, along with lifetime technical support from our team of certified electrical engineers. We maintain a global inventory network to ensure fast delivery, with standard orders shipped within 7-15 days and expedited options available for urgent requirements. Custom engineering services are also offered to meet specific project specifications and regional standards.
A disconnect switch is an off-load safety device designed exclusively to create a visible electrical break for maintenance purposes. It cannot interrupt load current or fault current. A circuit breaker, by contrast, is an on-load protection device that can safely interrupt normal operating currents and short-circuit currents to protect equipment and circuits. Disconnect switches must always be operated only after the circuit has been fully de-energized by a circuit breaker.
No. The RH-A series is specifically engineered for no-load operation only. Attempting to interrupt load current with this device will generate dangerous electric arcs that can cause severe equipment damage, personal injury or even death. Our electrical engineers strongly recommend verifying zero current status using appropriate test equipment before operating any disconnect switch.
Under normal operating conditions and with proper maintenance as outlined in the product manual, the RH-A series disconnect switches have a rated mechanical life of 10,000 operations. Regular inspection and lubrication of moving parts can significantly extend this service life.
Yes. We offer detailed installation guides and video tutorials for all our products. Our global network of certified service partners provides professional on-site installation, commissioning and preventive maintenance services. Our technical support team is available 24/7 to assist with any questions or issues you may encounter.
