Disconnect switch LBS 1250 4P 004661466

Disconnect switch – reliable power disconnection

The LBS 1250 4P disconnect switch is a solid and proven device designed for the safe disconnection of electrical circuits. It allows switching operations to be performed under load, providing a clear isolation gap. This is crucial in service, renovation and maintenance work. The device's construction, compliant with IEC 60947-3, guarantees reliability and safety of use.

Construction and application

The LBS 1250 4P disconnect switch is a permanently mounted device designed for mounting on a plate or in distribution boards. The four-pole design makes it ideal for protecting three-phase and single-phase circuits with a neutral conductor. The rated continuous current of 150 A and the maximum operating voltage of 415 V AC allow it to be used in a wide range of electrical installations with a power of up to 710 kW (for AC-23, 400 V). Thanks to the possibility of using a padlock, it can be protected against unauthorized switching.

• Safety first: Provides a safe isolation gap, minimizing the risk of electric shock during service work.
• Versatility: Suitable for AC networks with voltages up to 415 V and low-voltage DC circuits.
• Easy installation: Possibility of mounting on a plate, in distribution boards and on TH35 rail facilitates integration with existing infrastructure.
• Wide range of applications: Ideal for industrial, commercial and public utility building installations.
• Expandability: Compatible with additional auxiliary contacts LBS-PS11 and LBS-2PS11 to increase functionality.
• Clear status indicator: Allows unambiguous identification of the status of the main circuit contacts.

Additional accessories, such as terminal covers LBS-TS or handles (available separately), allow you to adapt the disconnect switch to specific installation needs. Please note that LBS disconnect switches are sold without a handle - you should select the appropriate model from the available accessories (single up to 630A or double-sided from 800A).
