Isolator switch 63A SV 263 002423214

Isolator – reliable disconnection in the installation

This two-pole SV 263 isolator with a rated current of 63A is a key element of every electrical installation where safe and reliable disconnection of the circuit is required. It will work both in residential and industrial installations, providing effective isolation and protection.

Functionality and application

The SV 263 isolator serves as a main switch in switchboards and as an individual switch in electrical installations. Its main task is to ensure safe disconnection of the circuit for maintenance, repair or emergency work. The lack of built-in overcurrent protection means that the device is used solely for circuit isolation, and protection against overloads and short circuits should be provided by appropriate circuit breakers. The ability to seal the lever in the "On" and "Off" positions further increases safety, preventing accidental switching of the circuit.

Construction features and parameters

The device is characterized by a solid fixed construction, which guarantees stability and reliability. Frame terminals facilitate the connection of wires with a cross-section from 2.5 mm² to 50 mm². The IP20 degree of protection provides protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm. The red lever intuitively indicates the status of the device. The isolator meets the standards PN-IEC 60947-3 and PN-EN 60947-3, which confirms its compliance with applicable safety standards. The rated operating voltage AC is 400V and the rated conditional short-circuit current Iq is 4kA. The creepage distance exceeds 3mm providing adequate insulation.
