PTTB 4-HESILED 24 (5X20)
Series PTTB

PTTB 4-HESILED 24 (5X20) - Fuse modular terminal block

Fuse modular terminal block, fuse type: Glass / ceramics / ..., fuse type: G / 5 x 20, nom. voltage: 24 V, nominal current: 28 A, connection method: Push-in connection, 1 level, Rated cross section: 4 mm2, cross section:  0.2 mm2- 6 mm2, connection method: Push-in connection, 2nd level, Rated cross section: 4 mm2, cross section:  0.2 mm2- 6 mm2, mounting type: NS 35/7,5, NS 35/15, color: black

  • The easily accessible fuse inserts are easy to use or replace
  • Convenient testing of fuses with test pick-offs on both sides
  • Quick identification of faulty fuses, thanks to LED status indicator
  • In addition to the testing option in the double function shaft, all terminal blocks provide an additional test pick-off
  • The Push-in connection terminal blocks are characterized by the system features of the CLIPLINE complete system and by easy and tool-free wiring of conductors with ferrules or solid conductors
  • The compact design and front connection enable wiring in a confined space
Technical Specifications

Notes

GeneralThe current is determined by the fuse used, the voltage by the light indicator.
