Disconnect switch OT40F3, 40A, 3-pole, without shaft and handle 1SCA104902R1001

Isolator switch – reliable disconnection in the installation

This three-pole OT40F3 isolator switch with a rated current of 40A is a robust solution for safely disconnecting electrical circuits. Designed for both plate mounting and switchgear cabinets, it provides effective isolation and protection of the installation. The lack of a shaft and handle makes it compact and easy to integrate with existing systems.

Functionality and application

The OT40F3 isolator switch is primarily used as a main or repair switch. It allows for safe disconnection of power during maintenance, repair or modernization work. Its design allows for easy and reliable disconnection of the circuit, minimizing the risk of accidents. Rated operating power up to 11 kW at 400V (AC-23) makes it suitable for various industrial and commercial applications.

• Safety first: Provides effective circuit isolation, protecting personnel during service work.
• Universal mounting: Possibility of mounting on a plate or in a switchgear cabinet increases installation flexibility.
• High durability: Withstood short-circuit current up to 0.5 kA guarantees reliable operation in harsh conditions.
• Compact dimensions: Width 35 mm, height 68 mm and depth 56 mm facilitate mounting even in limited space.
• Designed for operation: Rated operating voltage in the range of 750…750 V AC ensures compatibility with most standard installations.
• Solid connections: Screw connection of the main contacts guarantees a secure and durable connection of the wires.

Technical characteristics and construction

The isolator switch is made as a complete device in a housing, which ensures its durability and resistance to mechanical damage. The lack of auxiliary contacts (normally open, normally closed and changeover) simplifies the construction and reduces costs, while fulfilling the basic functions of the isolator switch. The degree of protection IP20 protects against accidental contact, and the black color of the control element ensures good visibility. The design does not have a locking mechanism, which facilitates quick operation of the switch.
