Isolating switch STV D02 63A 1P+N 002271002

Insulation disconnect switch – safety and reliability in your installation

The STV D02 63A 1p+N insulation disconnect switch is a key element ensuring the safe and efficient operation of the electrical installation. The device is designed to reliably disconnect circuits in emergency situations, during maintenance or repairs. The design of the disconnect switch allows for safe isolation of a section of the installation, minimizing the risk of electric shock.

Construction and application

The STV D02 disconnect switch from the D02 series is a modular device, mounted on a TH 35 rail. It is intended for use in circuits with a rated voltage of 230 V and a rated current of up to 63 A. The 1p+N version (single-pole with neutral conductor) is ideal for residential, commercial and industrial installations where disconnection of one circuit while maintaining the neutral is required. The possibility of mounting both “from above” and “from below” provides flexibility during installation and adaptation to the specifics of a particular project.

Key features and benefits

• Wide range of applications: Thanks to the possibility of cooperating with fuse links with a rated current from 2 to 63A, the STV D02 disconnect switch is a universal solution for various needs.
• Safety of use: The design ensures that it is impossible to touch live parts when replacing the fuse link, which increases the safety of the installer and end user.
• Selective cooperation: The use of a disconnect switch with a fuse link allows for selective cooperation with overcurrent protective circuit breakers, which improves the reliability of the entire system.
• Easy installation: Mounting on a standard TH 35 rail facilitates and speeds up installation.
• Possibility of sealing: The disconnect switch can be sealed in the ON or OFF position, even without a fuse link inserted, which prevents unauthorized activation of the installation.
• Compact dimensions: Allow mounting in tight switchgear spaces.

Technical parameters

The STV D02 disconnect switch is characterized by high quality workmanship and compliance with applicable safety standards. It has a working category of AC-22B and AC-23B (up to 35A). The rated short-circuit capacity is 50 kA, which guarantees effective protection against the effects of short circuits. The terminals of the disconnect switch allow connection of conductors with a cross-section from 1 to 35 mm². The rated insulation voltage is 500V and the impulse voltage 8kV.
