Isolating switch STV D02 63A 1P 002271001

Isolator switch – safety and functionality in one

The ETI STV D02 63A isolator switch is a reliable device for safely disconnecting electrical circuits. Designed for both home and industrial installations, it provides effective isolation and protection against short circuits and overloads. Its compact size and easy mounting on a TH35 rail make it an ideal solution for professionals and demanding users.

Construction and application

The STV D02 isolator switch has been designed with simplicity and functionality in mind. It allows for safe disconnection of the circuit for maintenance or repair work. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. The possibility of mounting both “from above” and “from below” increases installation flexibility. The device is adapted to cooperate with D0 series fuse links, which allows for protection of the circuit against overload. Replacing the fuse link is done safely, without the risk of touching live parts.

Key features and benefits

• Versatility: The rated current of the isolator switch can be adapted to the needs of the installation by using fuse links with a value from 2A to 63A.
• Safety: The design ensures that live parts cannot be touched during fuse link replacement.
• Mounting: Quick and easy mounting on a standard TH35 rail – saves time during installation.
• Selectivity: Possibility of cooperation with overcurrent installation circuit breakers, providing selective circuit protection.
• Sealing: Possibility of securing the isolator against accidental switching on or off by using seals.
• Rated voltage: Adapted to work in 230V AC and 110V DC networks (in the 2-pole version).
• Short-circuit capacity: High short-circuit capacity (50kA) ensures effective protection of the installation in the event of a short circuit.
