Isolator switch 3P 125A HA351

Isolator switch – safety and reliability in your installation

This three-pole isolator switch with a rated current of 125A is a key element of any electrical installation where manual disconnection of circuits and complete isolation are required. Designed for durability and functionality, it will work well in both domestic and industrial installations. Its solid construction guarantees safe and reliable operation for a long time.

Functionality and application

The device is designed to operate at a rated voltage of 380-415V and has a short-circuit capacity of up to 50kA, providing effective protection against the effects of overloads and short circuits. The possibility of mounting on a plate or in distribution boards increases its versatility. Thanks to the locking mechanism, it provides additional safety, preventing accidental switching on of the circuit during maintenance or repair work. It will work as a main switch, safety switch and repair switch.

Advantages for professionals and users

• Safety first: Complete circuit isolation after switching off – ideal for service and maintenance work.
• Universal mounting: Possibility of mounting on a plate, in distribution boards and any working position (360°) makes installation easier in various conditions.
• Durability and reliability: Mechanical endurance of 10,000 cycles and electrical endurance of 1500 cycles guarantees long device life.
• High switching capacity: Rated operating power for AC-23 at 400V is as much as 56 kW, allowing operation of demanding loads.
• Easy status identification: Long rotary handle makes it easy to visually check the status of the switch (on/off).
• Flexible connections: Cable clamps allow connection of wires with a cross-section from 1.5 mm² to 50 mm² (solid cores) or 1.5 mm² to 35 mm² (stranded cores).
• Possibility of sealing: Protects against unauthorized switching on of the device.

This switch is a solid solution for any installer looking for reliable equipment for building safe and functional electrical installations. For the end user, this means peace of mind and confidence that their installation is protected against failures and hazards.
