XCDS-10 Disconnect Terminal Block

The XCDS-10 is a 10 mm2 (6 AWG) knife disconnect terminal block designed for 35 mm DIN-rail mounting in industrial control panels, instrumentation loops, and power distribution systems. It provides a mechanical pivot lever to safely open and isolate individual electrical circuits for testing, calibration, and maintenance without disrupting permanent field wiring.

Pivoting Knife Disconnect: Features a hinged lever mechanism that opens manually and locks securely in the open position to prevent accidental reconnection under heavy machinery vibration.

Low-Resistance Current Bar: Machined from high-purity electrolytic copper alloy with uniform tin electroplating, ensuring minimal voltage drop and low thermal rise during continuous operation.

Vibration-Resistant Screw Clamping: Enclosed steel clamping yokes deliver consistent, uniform contact pressure on solid or stranded conductors, resisting loosening under high-vibration conditions.

PA66 Insulating Housing: Molded from virgin Polyamide 6.6, offering mechanical rigidity, creepage stability, and a continuous operating temperature range from -40°C to +105°C.

Standard EN 60715 Footprint: Snaps directly onto standard 35 mm top-hat DIN rails for space-efficient panel layouts.

PLC / DCS Signal Loops: Segmenting individual sensor or actuator circuits for diagnostic testing without removing panel field wires.

Secondary Transformer Circuits: Safe isolation of current transformers (CT) and protection relay test circuits.

Industrial Machine Tools (OEM): Circuit segmentation and logic verification during Factory Acceptance Testing (FAT) and field commissioning.

Power Distribution Panels: Auxiliary power supply control and meter testing isolation.

Supported by in-house tooling and vertically integrated manufacturing lines for volume panel builders:

Housing Colors: Standard gray, with optional colors (blue, red, black, yellow/green) available for dedicated circuit classification.

Laser Marking: Permanent laser engraving of custom terminal block numbers, circuit identifiers, or corporate branding.

Pre-Assembled DIN Rail Units: Delivery of customized terminal assemblies pre-loaded with end brackets, partition plates, and jumpers according to customer CAD schematics.

Production and process consistency are managed through direct factory execution:

In-House Tooling & Electric Injection: Multi-cavity molds running on high-tonnage Japanese electric injection presses to maintain uniform wall thickness and dimensional stability in PA66 housings.

Automated Machining & Plating: High-speed automatic lathes produce copper current bars and steel yokes, paired with automated barrel plating lines with monitored coating thickness.

Laboratory Testing Protocols: Batch sample testing is performed in accordance with industrial standards:
Conductor Pull-Out Force and Screw Torque Verification (IEC 60947 standard)
Temperature Rise and Current-Carrying Limit Testing
96-Hour Salt Spray Corrosion Resistance Testing on metal parts
Power Frequency Dielectric Withstand and Impulse Breakdown Tests
