Disconnect switch 40A SV 140 002423123

The SV 140 isolating switch is a reliable device designed for the safe disconnection of electrical circuits. It finds application in both residential and industrial installations where reliable operation and the ability to visually verify the circuit status are required. It is a key element in ensuring safety during maintenance, repairs or modernization of electrical installations.

Features and application

This single-pole isolating switch with a rated current of 40A is designed for mounting on a TH rail. Its construction allows it to be used as a main switch, safety switch or repair switch. Thanks to the possibility of sealing in the ON and OFF positions, it provides additional protection against accidental switching on or off of the circuit during service work. The rated operating voltage AC is 230V, and the rated conditional short-circuit current Iq is 2kA. Made of durable materials, it ensures long-lasting and trouble-free operation.

Construction and mounting

The SV 140 isolating switch is characterized by a simple and functional design. It has a red lever to facilitate identification of the circuit status (on/off). Frame clamps allow easy and secure connection of wires with a cross-section from 1 to 25 mm². The device is permanently mounted and has a degree of protection IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The possibility of power supply from the top and bottom and double connection of the insulating busbar increase the flexibility of mounting. The contact position indicator allows for unambiguous visual control of the switch status.

Safety and compliance with standards

The SV 140 isolating switch meets the requirements of PN-IEC 60947-3 and PN-EN 60947-3 standards, which guarantees its safety and reliability. The possibility of using an optional overvoltage release further increases the level of protection of the electrical installation. The device is intended for installation in switchgear cabinets and is characterized by a permanently mounted device construction.
