UNITECK Solar Switch 50A - Bipolar DC Switch-Disconnector for Solar PV Systems

Ensure the absolute safety and control of your solar power installation with the UNITECK Solar Switch 50A, an essential component for any high-performance photovoltaic (PV) system. Engineered for uncompromising reliability, this high-quality switch serves as the master control point for your DC circuits, providing the critical ability to safely isolate power for maintenance, system checks, or in the event of an emergency. Designed for both professional installers and serious DIY enthusiasts, this switch-disconnector is the cornerstone of a secure and professionally managed solar energy setup, offering peace of mind and adherence to the highest safety standards in the industry. Its robust construction and superior electrical characteristics make it an indispensable part of the electrical connections for residential, commercial, or off-grid solar projects.

Bipolar switch-disconnector ideal for safe operation of solar systems up to 500V DC (installation, maintenance or emergency intervention).

Designed to operate even under load, with no risk to the switch-disconnector and ensures rapid arc extinction when operated.

PV1/PV2 certified, it offers ideal protection, particularly in thermal applications between -40°C and -85°C.

Padlockable, 2 mounting options:wall-mounted or on 35 mm Din rail.



Unmatched Safety and Performance Under Load

One of the most critical features of the UNITECK Solar Switch is its proven ability to be operated safely while the system is under full load. Unlike standard isolators, this advanced switch is specifically engineered to handle the disconnection of active DC circuits up to 50A and 500V without risk of damage to the unit or creating a dangerous electrical arc. The internal mechanism guarantees rapid and effective arc extinction, a vital safety feature that protects both your equipment and personnel from the significant hazards associated with DC power. This capability means you can confidently and immediately shut down your system whenever necessary, without a complex or risky power-down sequence.

Built for Durability in Extreme Environments

Your solar installation is exposed to the elements 24/7, and every component must be able to withstand them. The UNITECK 50A Solar Switch excels in this regard, holding PV1/PV2 certifications that attest to its suitability for demanding photovoltaic applications. It is designed to deliver flawless performance across an exceptionally wide operating temperature range, from a frigid -40°C to a scorching +85°C. This thermal resilience ensures that the switch will not fail, degrade, or become a point of weakness in your system, regardless of the climate. Its robust build quality provides long-term protection for your investment, ensuring reliable operation for years to come.

Versatile Installation and Enhanced Security

Flexibility and security are paramount in any electrical installation. This switch offers two convenient mounting options to suit any setup: it can be easily surface-mounted on a wall or seamlessly integrated into a standard electrical enclosure using a 35 mm DIN rail. This versatility simplifies the installation process and ensures a clean, professional finish. For enhanced safety and compliance with Lockout-Tagout (LOTO) procedures, the switch is padlockable. This essential feature allows maintenance technicians to physically lock the switch in the "off" position, preventing accidental or unauthorized re-energizing of the circuit while work is being performed, thereby providing the highest level of personnel safety.
