Semiflush-Mounted Test Switch - 10 Pole

This semiflush-mounted test switch is part of a line of knife-type test switches engineered to the strictest security standards in the electric sector, giving panel operators safe, direct access to relays and energy measuring devices during live testing and calibration. Using the switch's key, all test and inspection operations are performed through the front of the panel, avoiding any contact between the operator and the energized parts of the system. Each knife switch is individual, separated by molded insulating barriers, and equipped with a key injected in highly resistant material, available in color options for circuit identification and fitted with pins for mechanical interlocking.

Rated for 600V and 20A with a 2.5kV insulation class, this test switch is configured with up to 10 poles in a semi-inbuilt assembly, with terminals located at the rear of the key and separated by high-isolation barriers that provide appropriate space for wiring connections. Its semi-flush-mounted design allows the switch to be installed with the terminal block set back from the panel face while keeping full front-of-panel testing access for operators.

Typical applications include potential and current testing on protective relays, energy metering equipment, and other panel-mounted instrumentation in utility and industrial settings, wherever operators need to test, calibrate, or monitor live circuits without shutting down the system. This test switch is 100% factory tested on automated test benches, backed by a full warranty, and manufactured by an ISO 9001 certified company with more than 20 years of experience in the measurement and protection segment.
