UNITECK Solar Switch 32A | 500V DC Bipolar Disconnector for PV Systems

Ensure the absolute safety and operational integrity of your photovoltaic installation with the UNITECK Solar Switch 32A. As a critical component in any professionally designed solar power system, this switch-disconnector provides the essential means to safely isolate your solar panel arrays from the rest of your system. It is specifically engineered to guarantee maximum protection for personnel during installation, routine maintenance, or in the event of an emergency, offering complete peace of mind. This robust device is the cornerstone of a secure and compliant solar energy setup, from small residential projects to larger commercial applications.

The UNITECK Solar Switch is a high-performance, 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.

Uncompromising Performance and Safety Under Load

One of the most significant advantages of this UNITECK switch is its proven ability to perform a "load-break." Unlike standard isolators, this switch is engineered to be safely operated while the solar system is actively generating power. This means you can confidently cut the DC current without first shutting down your inverter or waiting for nightfall. This capability is enabled by an advanced internal mechanism that ensures rapid and effective arc extinction. When the circuit is broken under load, a dangerous electrical arc can form; this switch is designed to quench that arc instantly, preventing damage to the switch itself, associated equipment, and eliminating a significant fire and safety hazard. This feature is indispensable for emergency shutdowns and simplifies maintenance procedures immensely.

Engineered for Durability in Harshest Conditions

Built to last, the UNITECK Solar Switch is certified to PV1/PV2 standards, confirming its suitability for demanding photovoltaic applications. Its exceptional resilience is highlighted by an incredibly wide operating temperature range, from a frigid -40°C to a scorching +85°C. This ensures reliable and consistent performance whether your installation is located in a cold mountain climate or a hot desert environment. The robust construction guarantees longevity and protects your investment by minimizing points of failure within your system’s electrical connections.

Versatile Installation and Enhanced Security

Flexibility is key to a clean and efficient installation. This DC safety switch offers two convenient mounting options to suit any setup. It can be easily surface-mounted directly onto a wall or seamlessly integrated into a standard electrical cabinet by clipping it onto a 35mm DIN rail. To meet the highest safety standards and comply with lockout/tagout (LOTO) procedures, the operating handle is padlockable. This crucial feature allows technicians to lock the switch in the "OFF" position, physically preventing the system from being re-energized while work is being performed, thus ensuring the ultimate protection against accidental startup.
