Disconnect switch LBS 250 4P 004661462

Insulating disconnect switch – reliable protection for your installation

The LBS 250 4P disconnect switch is a solid and proven solution for safely disconnecting electrical circuits. Designed for both professional and demanding users, it provides effective isolation and protection against overload and short circuit. The device is particularly recommended for installations with voltages up to 415V AC and in DC circuits.

Functionality and application

This four-pole disconnect switch is perfect as a main switch, safety switch, and maintenance switch. The ability to perform switching operations under load increases its versatility, and the high rated continuous current (250A) and operating power (132 kW for AC-23, 400V) allow its use in demanding industrial and commercial applications. The device's construction allows for mounting on a plate, 4-hole panel, and in distribution boards, providing flexibility during installation.

Characteristic features and benefits

• Safety first: Double insulation gap in each pole guarantees full protection for the operator during maintenance or repair. The contact position indicator facilitates visual monitoring of the device's status.

• Universal mounting: The ability to mount on a plate, 4-hole panel, or directly in distribution boards allows for adaptation to different installation configurations.

• Expandability: Thanks to the possibility of adding auxiliary contacts LBS-PS11 and LBS-2PS11, the disconnect switch can be integrated with control and signaling systems.

• Protection against unauthorized access: The possibility of using a padlock to lock the drive lever protects against accidental or intentional power disconnection by unauthorized persons.

• Compliance with standards: The disconnect switch has been designed, tested, and certified in accordance with IEC 60947-3, confirming its high quality and reliability.

• Durable construction: The permanently mounted device is characterized by solid workmanship and resistance to mechanical damage.

• Status indicator: Allows unambiguous determination of the position of the main contacts, which facilitates diagnostics and servicing of the installation.

The disconnect switch is characterized by a rated continuous current of 250A, has 4 poles and is adapted to operate at a maximum AC voltage of 415V. Its rated operating power for AC-23 at 400V is 132 kW, and the degree of protection is IP20.

Remember that to ensure proper operation of the disconnect switch, you need to purchase an appropriate handle (available models up to 630A – single handle and from 800A – double-sided handle).
