Isolating Switch SPX-D – Safety and Reliability in Electrical Installations

The isolating switch SPX-D 3P 400A NH02 is designed for the safe disconnection of electrical circuits, providing effective insulation and protection against accidental short circuits. It is a critical component in electrical installations, both in commercial and industrial buildings. The switch’s design allows for the installation of NH02 fuses, enhancing the functionality and safety of the entire system.

Construction and Installation

The SPX-D isolating switch features a robust construction and easy mounting on a mounting panel. Its dimensions — 274 mm width, 246 mm height, and 214 mm depth — enable convenient placement in electrical distribution boards. The three-pole (3P) design ensures complete isolation of all phases, while the cover provides additional protection against accidental contact with live parts. The switch is compatible with NH02 fuses, allowing flexible adaptation to specific installation requirements.

Applications and Benefits

This isolating switch is suitable for applications requiring safe disconnection of electrical circuits with a rated current up to 400A. It is ideal for:

• Main distribution boards: as a component enabling disconnection of the entire installation during faults or maintenance.
• Sub-distribution boards: for isolating individual circuits powering machines or equipment.
• Industrial installations: where high reliability and safety are essential.
• Commercial buildings: ensuring safe power disconnection during emergencies or renovations.

Using the SPX-D isolating switch delivers:

• Enhanced safety: Effective circuit isolation protects personnel from electric shock.
• Reliable operation: Robust construction ensures long-term, fault-free performance.
• Ease of use: Intuitive operation enables quick and safe circuit disconnection.
• Compatibility: Support for NH02 fuses provides flexibility in protective device selection.
• Clear installation layout: Clear labeling and solid design simplify identification and servicing.
