Disconnect switch LBS 1250 3P 004661456

Isolator switch – reliable installation protection

The LBS 1250 3P isolator switch is a solid and proven solution for safely disconnecting electrical circuits. Designed for use in both industry and commercial construction, it provides effective isolation and allows for safe switching operations under load. The device is particularly recommended where high reliability and resistance to working conditions are required.

Construction and application

The LBS 1250 3P isolator switch is designed for mounting on a plate or in distribution boards, providing installation flexibility. Its three-pole design allows simultaneous disconnection of all phases, guaranteeing complete safety. The device finds application in AC networks with a voltage of up to 415V and in direct current (DC) circuits. It meets the requirements of IEC 60947-3 standard, confirming its high quality and compliance with applicable standards. Its main function is to provide safe isolation of the circuit during maintenance, repair or failure.

Key features and benefits

• High rated current: Rated current of 150 A and the ability to operate under load up to 710 kW (for AC-23, 400 V) make the isolator perfect for demanding applications.
• Universal mounting: Possibility of mounting on a plate, in distribution boards and on the front panel (although not centrally) facilitates integration with various electrical systems.
• Safety of use: Double isolation gap and contact position indicator ensure certain disconnection of the circuit and minimize the risk of electric shock. The possibility of using a padlock provides additional protection against unauthorized switching.
• Expandability: Compatibility with additional auxiliary contacts (LBS-PS11 and LBS-2PS11) allows you to adapt the functionality of the isolator to specific installation needs.
• Durable construction: The permanently mounted device is characterized by a solid construction and high resistance to mechanical damage.
• Isolation gap: Provides a safe isolation gap in any low-voltage electrical circuit.
• Application: Ideal as a main, safety or maintenance isolator – versatile use in various types of electrical installations.

Additional information: The isolator is sold without a handle – you should select the appropriate model from the accessories (single for up to 630A or double-sided from 800A). Remember to choose the right handle model!
