Ultra‑Compact DIN‑Rail Design: Installs on standard DIN rails or panel Surface, saving panel space compared to standard long rear test switches.
Fail‑Proof CT Shorting: Keyedbuilt‑in disconnect pins ensure proper CT shorting, unlike external shorting bridges that can be misinstalled.
Enhanced Safety: No exposed metallic parts. The DRS features a finger-safe design to maximize user protection during testing procedures.
Visual Status Feedback: Transparent plastic front allow operators to visually confirm whether contacts are open or closed.
Quick Front‑Access Testing: Banana jacks on the front panel let technicians perform secondary injection without rewiring.
Wire Terminal Options: Available with both screw and stud terminals, replicating FT Switch configurations for maximum compatibility and convenience.
Modular Pole Configuration: Offered in even-numbered configurations from 4 to 20 poles, enabling flexible adaptation to various applications.
Normally Closed Default: Once the disconnect pin is returned to its parking position, internal springs re-establish the closed-circuit state automatically and reliably.

Key Features
Two‑in‑One Product: Combines a test interface and terminal block in a single compact device.
Finger-safe: There are no exposed metallic parts on the DRS, greatly increasing safety during testing.
High Electrical Rating: 600 V / 30 A continuous operation.
Keyed Disconnect Pins: Disconnect pins are keyed to the corresponding slots of the test block, preventing mistakes and errors during test.
Built-In CT-Shorting: When a disconnect pin is inserted, the circuit is completely isolated. Internal shorting bridges in current circuits ensure safety. There is no intermediate position, eliminating partial contact risks.
Transparent Front: Transparent plastic front of the DRS allows visual inspection of the internal contacts position (open or closed).
Flame Retardant: DRS test blocks are classified as UL94 V-0, indicating a high level of flame resistance.
Wire Terminals: A screw terminal and a stud terminal version are available.
Less than 2 mΩ internal resistance: Thanks to the patented construction, DRS Switches boast an extremely low internal resistance. This ensures a lighter load on instrumentation transformers and no impact on heat generation within panels.
DIN‑Rail or Surface Mount: Snap‑on mounting for fast installation in tight substations or meter boxes.
