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.
