Description

Lovato's SM1RT are circuit breakers with thermal and magnetic trip releases intended specifically for transformers control and protection

  • General characteristics
    • The magnetic trip threshold of 20 x In enable the connection of transformers avoiding unintentional tripping due to the high in-rush currents
    • The various adjustment ranges from 0.1A to 25A enable control and protection of transformers up to 17kVA (400V)
  • Operational characteristics
    • IEC rated insulation voltage Ui: 690V
    • IEC rated impulse withstand voltage: 6kV
    • IEC rated frequency: 50/60Hz
    • Maximum rated current: 25A
    • Max. heat dissipation per phase: 0.7...3.4 W
    • Magnetic tripping: 20 x In max
    • (16 x In max for SM1RT0016, SM1RT2300, SM1RT2500)
    • Mechanical and electrical life: 100.000 cycles
    • Mounting on 35mm DIN rail (IEC/EN/BS 60715)
    • Mounting position: Any
    • IEC utilisation category: A
    • Padlocking in OFF: Ø4mm/0.16”
    • IEC degree of protection: IP20.
