The JHT5 Distribution Terminal Block is a high-performance power distribution solution designed for safely connecting and distributing electricity through copper (Cu) and aluminum (Al) conductors. Manufactured using flame-retardant PA (nylon) housing and featuring a corrosion-resistant nickel-plated brass conductive core, this terminal block is engineered to deliver stable electrical performance even under high loads and harsh environments.
This terminal block supports a range of conductor sizes:
Copper: 2.5–50mm²
Aluminum: 6–50mm²
Rated Voltage: 800V
Rated Current: 160A (Cu) / 145A (Al)
It's available in multiple models and colors, including yellow/green (for grounding), grey, and blue/grey, with optional configurations for single or dual-pole connections. All models are compatible with C45 DIN rail mounting systems (TH35-7.5), ensuring easy integration into industrial distribution panels.
Step 1: Preparation
Ensure that the terminal block is mounted onto a DIN rail securely. The back slot of the block fits perfectly on TH35-7.5 rails, providing a firm mechanical hold.
Step 2: Strip the Wires
Strip the insulation from copper or aluminum conductors according to the recommended strip length. For optimal connection, the conductor should be fully exposed and clean.
Step 3: Insert the Conductors
Insert the stripped wire into the wiring hole. The JHT5 features nickel-plated brass blocks with chamfered entry holes for smooth insertion and anti-slip structure.
Step 4: Tighten the Screws
Use a 5mm inner hexagon screwdriver to tighten the terminal screws. Ensure the connection is firm to prevent overheating or disconnection.
Step 5: Cover the Unit
Snap the colored PC cover plate back onto the housing. The cover is not only insulating but also provides visual guidance for wire identification and enhances safety.
The JHT5 Distribution Terminal Block is engineered for high-current, high-voltage industrial and commercial applications. Its thoughtful design and superior materials make it a reliable choice for power distribution.
