1000V DC Isolator Switches IP66

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. The switch supports a maximum voltage of up to 1000V DC and is constructed with high-quality components for stability and durability.

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, and offers ingress protection rated at IP66, making it suitable for both indoor and outdoor environments.

Electrical Characteristics: The switch has a rated insulation voltage (Ui) of 1200V, an overvoltage category of II, and a rated conditional short-circuit current (Icn) of 3kA. It is designed for a service life of 1000 mechanical and electrical cycles.

Installation and Environment: The BYH Series can be mounted vertically or horizontally and is suitable for environments with temperatures ranging from -40°C to +85°C. It is designed to withstand pollution degree 3 and is suitable for both indoor and outdoor use.

Additional Features: The switch includes a breathing valve to prevent condensation, a waterproof plug, and a sealing plug. It is equipped with a lockable knob for secure operation and is capable of isolating without polarity, allowing interchangeability of “+” and “-” polarities.

Wiring and Connections: The switch uses screw terminals for the main circuit, supporting a cross-section area of 4.0-16mm² for rigid conductors and 4-10mm² for flexible conductors. The tightening torque for the main circuit is between 1.2Nm and 1.8Nm.

Remarks: The ZJBENY DC Isolator is designed to perform well in waterproof conditions and can be installed in any direction. It is important to ensure all connections are suitable for the rated current and are properly tightened before energization.
