BYH Series Non-polarity DC Isolator Switch

Product catalog summary

Introduction: The BYH Series DC Isolator Switch is designed for use in residential or commercial photovoltaic systems, positioned between photovoltaic modules and inverters. It features a rapid arcing time of less than 3ms, ensuring enhanced safety and longevity due to high-quality components. The switch supports a maximum voltage of 1000V DC and is IP66 rated for UV resistance and waterproofing.

Specifications: The isolator switch is available in 2-pole and 4-pole configurations, with a rated operational voltage of up to 1000V DC and a rated operational current of 32A. It is compliant with IEC60947-3 and AS60947.3 standards. The switch is suitable for both indoor and outdoor environments, with an operational temperature range of -40°C to +85°C.

Electrical Characteristics: The switch has a rated insulation voltage of 1200V and a rated conditional short-circuit current of 3kA. It is categorized under DC-PV2 / DC-21B utilization and supports non-polarity, allowing interchangeable '+' and '-' polarities.

Installation and Operation: The switch can be mounted vertically or horizontally and is equipped with a breathing valve to prevent condensation. It is designed for easy installation with screw terminals and supports a conductor cross-section area of 4.0-16mm². The tightening torque for the main circuit is between 1.2Nm and 1.8Nm.

Environmental and Safety Features: The isolator switch is rated for a pollution degree of 3 and is suitable for environments with temperatures ranging from -40°C to +85°C. It is designed to be waterproof and can be installed in any direction while maintaining performance.

Additional Features: The switch includes a locking mechanism for safety and a waterproof plug. It is designed to handle a rated impulse withstand voltage of 8.0kV and has a service life of 1000 cycles for both mechanical and electrical operations.
