XCDT-6 DIN Rail Terminal Block - Technical Specification & Sourcing Guide

The XCDT-6 is a 6mm standard screw-connection feed-through DIN rail terminal block engineered for industrial control panels, switchgear, and power distribution networks. Designed for secure conductor retention and minimal contact resistance, it mounts directly onto standard 35mm DIN rails (EN 60715). Molded from virgin polyamide (PA66) and equipped with high-conductivity brass current bars, the XCDT-6 accommodates solid and stranded conductors up to 6 mm2 (10 AWG).

Standard Stock Availability: Standard grey configurations are maintained in stock for 48-hour sample dispatch.

Key Features

Vibration-Resistant Clamping Yoke: Hardened steel clamping system with elastic deflection properties, preventing screw back-off and conductor loosening under continuous industrial vibration.

Low Millivolt Drop: Tin-plated electrolytic copper-alloy current bars maintain ultra-low contact resistance (< 0.8 mV) at rated current.

Modular Potential Distribution: Central jumper channels accommodate standard plug-in FBS bridges for rapid multi-tier power bridging.

Flame-Retardant Housing: Molded from virgin PA66 (UL94 V-0 flammability rating), offering high thermal stability across -40°C to +105°C and CTI 600 tracking resistance.

Standardized Marking Zones: Integrated marker carriers accept standard snap-on strip markers for clear circuit identification.

FAQ

Q: Are XCDT-6 terminal blocks dimensionally compatible with major brands like Phoenix Contact or Wago?

A: Yes. The XCDT-6 shares standard profile geometry and pitch dimensions with 6 mm feed-through blocks, ensuring full compatibility with standard plug-in bridges, end brackets, and marking accessories.

Q: What is the recommended tightening torque for the screw clamp?

A: The recommended torque is 0.6 to 0.8 Nm using a standard flat-head screwdriver (PH1 or 0.6 x 3.5 mm blade). Torques exceeding 1.0 Nm risk stripping the internal thread.

Q: Do these terminal blocks withstand high-vibration railway or marine environments?

A: Yes. The steel clamping yoke incorporates an engineered spring-action design that absorbs mechanical shocks and maintains constant contact pressure on stranded wires, preventing loosening under high vibration.

Q: What certifications accompany the XCDT-6 series?

A: They are fully certified under CE (IEC 60947-7-1) and UL 1059 standards, adhering to RoHS and REACH environmental directives. Complete compliance certificates are available on request.

Q: What is the minimum order quantity (MOQ) for non-standard housing colors?

A: The MOQ for custom color variants (such as blue, red, or yellow) is 3,000 pieces per color.

Q: How do you guarantee consistent electrical conductivity across production batches?

A: We analyze incoming brass alloys using direct-reading spectrometers prior to stamping, and monitor electro-tin plating thickness via X-ray fluorescence (XRF) inspection on every production lot.
