Disconnect switch 3P 160A HA352

Disconnect switch – reliable power disconnection

The 3P 160A disconnect switch is a key element of every electrical installation, providing safe and reliable disconnection of the circuit. Designed for use in both commercial and industrial applications, it allows for effective isolation of equipment during maintenance, repairs or failures. Its solid construction and high technical parameters guarantee long-lasting and trouble-free operation.

Functionality and application

This device finds wide application as a safety, maintenance and main switch. Thanks to the possibility of manual control, it allows for full control over the electrical circuit. The rated continuous current of 160A makes it ideal for protecting medium and high power loads. The possibility of mounting on a plate and in distribution boards increases its versatility and facilitates integration with existing infrastructure. Equipped with a long rotating handle, it provides convenient and ergonomic operation.

Key features and benefits

• Safety first: The safety switch function guarantees effective circuit isolation in emergency situations or during maintenance work.
• Versatile mounting: The possibility of mounting on a plate and in distribution boards makes it easy to adapt to different installation configurations.
• High durability: Rated short-circuit withstand current of 7 kA provides resistance to overloads and short circuits.
• Solid construction: The device is permanently mounted, which translates into stability and reliability of operation.
• Convenient operation: The long rotating handle makes it easy to operate the switch even in difficult conditions.
• Protection against accidental switching on: The locking mechanism prevents unintentional starting of the circuit during service work.
• High switching capacity: Switching capacity at 400 V is as high as 105 kW, allowing protection of even demanding receivers.
• Cable lugs: Allow easy and secure connection of cables of various thicknesses.

Technical parameters in practice

The switch is characterized by a rated operating voltage in the range of 380-415 V, which makes it compatible with most standard electrical installations in Poland. The rated operating power for AC-23 at 400 V is 72 kW, and for AC-21 – 160 A, which confirms its high efficiency. The lack of normally open and changeover auxiliary contacts simplifies the device's construction and increases its reliability. The IP00 protection class indicates the lack of protection against access to live parts – therefore, special care must be taken during installation and operation.
