283 series 0.2-16mm ² high current through/ground terminal block compatible with medium power power circuits, supporting step-down jumpers, common potential rated voltage 800V, rated current 76A, motor control, power distribution

284 series 0.2-10mm ² high current through/fuse terminal block with fuse holder, supporting 35mm ² conductor distribution rated voltage 800V, rated current 57A, power circuit overload protection

285 series 6-35mm ² ultra-high current terminal block is suitable for heavy-duty power circuits, with copper bars connected to industrial power supply main lines and high-power equipment with a rated voltage of 1000V and a rated current of 125A

Detailed explanation of special types:

Fused terminal block: compatible with glass fuses of 5x20/25/30mm, 1/4 "x1" and other specifications. Some models come with LED or neon light fuse indication and support quick replacement of fuses (one end automatically pops out when the cover is opened).

Double/triple layer terminal block: The upper and lower layers are designed to be independent or have a common potential, saving rail space and adapting to motor L1/L2/L3/GND multi potential wiring.

Isolation switch terminal block: equipped with sliding isolation switch, supporting circuit power-off maintenance, and some with locking function to prevent accidental closing.

2. Pluggable connector terminal block (X-COM) ®- SYSTEM， 769/870 series)

Series positioning: For scenarios that require frequent maintenance and quick plugging, supporting modular combination.

Core product type:

Carrier terminal block (769 series): 1-4 pole design, including through/isolation switch/diode/LED types, compatible with 0.08-4mm ² conductors, rated current 16-32A, supports coding error prevention (16 coding combinations).

Double layer carrier terminal block (870 series): 2-4 pole double-layer design, supports L/N/GND multi potential distribution, compatible with 0.08-2.5mm ² conductors, rated current 16A.

Supporting plug: 1-15 pole straight/curved plug, with strain relief board, locking lever, protective cable pulling, supporting multiple plugs with common potential.

Core advantage: The plug and terminal block can be quickly separated, and there is no need to disconnect the wires during maintenance; Encode the key to prevent accidental insertion and improve wiring accuracy.
