TXH TYPE HIGH WITHSTAND VOLTAGE TERMINAL BLOCK
FEATURES
High insulation voltage
Rated insulation voltage is 1,000V AC / 1,500V DC, and power-frequency withstand voltage is 5,000V AC / 1 min. (IEC60947)
High performance resin material
High performance modified-PPE is used as modeling resin material. Flame resistance is UL94 V-0 grade, comparative tracking index (CTI) is more than 600.
Easy mount and dismount
Terminal block can be mounted and dismounted from the rail unit by unit without removing end clamp.
Finger protection
Finger protection structure on terminal-portion prevents touching live portion even if terminal cover is not attached.
Wire cover
Insulation distance can be kept without insulation cap by attaching a wire cover.
* Please make insulation protection applicable to equipment and voltage.
* Wire cover (TXH-□-CV) is not included in terminal block order.
