SP 9075

Fuse monitoring in the three-phase mains, e.g. for automatic switching-off and switch-on blockage of three-phase motors in the event of one or more phase fuses failing.

• According to IEC/EN 60255-1
• Recognizes fuse failures in three-phase mains up to 3 AC 690 V
• Can be used for all types and sizes of fuses
• Independent of phase sequence
• Signals even if loads are switched off
• No malfunction on
  - Asymmetrical mains
  - Mains with harmonic waves
  - Motors producing feedback
• Shorter response time than with motor circuit-breakers
• Green LED for intact fuses
• Red LED for fuse failure
• As option: Energized / de-energized on trip in the case of IP 9075 programmable via X4-X5 or X3-X4
• As option: With manual reset function and remote reset, programmable via X1-X2
• As option: 1 NO contact or 2 changeover contacts
• Devices available in 2 enclosure versions:
  I-model: Depth 59 mm, with terminals at the bottom for installation systems and industrial distribution systems according to DIN 43 880
  S-model: Depth 98 mm, with terminals at the top for cabinets with mounting plate and cable duct
• IL 9075, SL 9075: Width 35 mm
