TXH TYPE HIGH WITHSTAND VOLTAGE TERMINAL BLOCK

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.

Applicable standard: IEC 60947-7-7-1(2009)
