Busbar quick connect fire resistant plastic feed through wire electric copper screw clamp din rail connector terminal block

Our Advantage

1.Professional: Since 2001, we have served more than 2000 customers.

2.Excellent performance: self-locking,vibration resistance, loosening protection, low electric resistance and excellent gas-tight, excellent pliability and fire resistance.

3.Rich product range: the connect capacity ranges from 0.5 to 35 mm2 with terminals of test,disconnection,fuse types etc.

4.Factory direct price: have the best price/performance ratio.

5.Good quality: strictly following IEC-60947-7-1 standard. we choose the best material for our product, and all of our product get the certificate of CE, ROHS, ISO9001, and pass the product type-test by authorized 3rd party in China. We have zero-tolerance for any flaw of a small part.

6.Service: we can provide OEM serives,and our quick response within 24 hours.


WJHT series terminal blocks can be assembled to different length to be suitable for the junction box or electrical cabinet. Detailed marking system can help you manage your wires efficiently. The high reliability and robust design adapts vibration and harsh thermal variation to prevent terminal connection fault.

1.The Insulation materials PA66 : It has excellent electric and mechanical properties, and the flame resistance rating is V0 grade.

Specific resistivity (Ω/cm)1012 (VDE0303 T.30)
Dielectric strength (KV/mm)30 (VDE0303 T.2)
Comparative tracking index CTI (V)600 (VDE0303 T.1)
Continuous service temperature (℃)100 (VDE0304 T.21)
Lower temperature limit static (℃)-50
Flammability according to UI94 is HB or V0UI94

2.High quality conducting strip: use the redcopper conducting strip which have the good electrical conductivity and quality ensure.
3.Reliable connection: reliable clamping yoke.The flat base of the clamping unit ensures that even the thinnest connection leads can be clamped tightly. The transverse grooves of the current bar can break the oxide film on the conductor at several points to provide a good connection without wrenching. The stable clamping unit with a small manufacturing deviation provides a high contact pressure to keep a gas-tight connectionto effectively avoid any gas erosion. Thus a long-term and stable connection is guaranteed even in an erosive ambient.
4.Self-locking of screws: WJHT Copper terminal blocks ensure a tight connection and prevent screws self-loosening by"Reakdyn principle". The clampingunits for cross sections of up to 10mm are designed as cages. The working principle is based on "the cage principle".When the screw is tightened, the head of the screw is above the current barwhile the clamping unit moving upwards. Then the conductorthe clamping unit is tightened with the current bar. The high contact force makes the conductor inserted to the self tin-platingm of the current bar. The transmit electrical resistance in a 4mterminal is only 0.1mn, which is obviously lower than the lowestvalue according to IEC947-7-1 With clamping part with cages the screws are secured by means of the"Reakdyn groove "on the upper side of the cage. Whenthe screw is tightened with a bigger torque, an elastic deformation occurs in the cage. In conjunction with the thread friction and theerent elasticity of the cage material, this deformation effective and progressively prevents the screw loosening
5.Anti- aging gas tight: Due to constant changes of temperature and humidity, a terminal blockis expected to have exce lent anti-aging and gas-tight property toguarantee a good mechanical and electrical property.A strong contact force creates a tight contact between the conductor and the current bar, Reduce the contact resistance and effectuating gas-tight to prevent air-erosion Even after used in extremely aggressive atmosphere, the large contact zone free from air-erosion is still clear onboth the conductor and the current bar.
