    Miniature circuit breakers

    Miniature circuit breakers

    Mors Smitt offers a wide range of railway hydraulic magnetic circuit breakers. The circuit
    breakers are fully configurable to meet the individual requirements.
    Advantages
    • Precise, temperature stable mechanism, due to hydraulic magnetic technology
    • Overcurrent sensing mechanism reacts only to changes of current
    • No ‘warm-up’ period to slow down its response to overload. No ‘cooldown’ period after overload before it can be reset. Derating considerations due to temperature variations are not normally required and heat-induced nuisance tripping is avoided
    • A common trip linkage between all poles, another safety feature, ensures that an overload in one pole will trip all adjacent poles
    • A trip-free mechanism, a safety feature, makes it impossible to manually hold the contacts closed during overcurrent or fault conditions
    • Standard dimensions, mounting and current ratings provide maximum application
      versatility
    • Wide range: current ratings to 700 Amps and rated voltages to 600 VAC and 110 VDC are available
    • Options: series trip, mid-trip, switch only (with or without auxiliary switch), remote
      shutdown, shunt trip, and dual coil circuit options are available
    Standards
    The Mors Smitt minature circuit breakers are designed according the following railway
    standards:
    • IEC 60077 Electrical equipment for rolling stock in railway applications
    • EN 50155 Electronic equipment used on rolling stock for railway applications
    • EN 45545-2 Fire protection on railway vehicles
    • NF F16-101/-102 Fire behavior - Railway rolling stock
    • IEC 61373 Shock & vibration resistance - Railway rolling stock
