MICROMASTER 410 – The price-conscious unit for standard tasks


Micromaster 410The simple solution for simple tasks. Optimally tailored to the requirements in the power range from 0.12 kW to 0.75 kW, the MICROMASTER 410 is the cost-effective solution for variable speed 3-phase motors on single-phase networks. The compact design makes installation and commissioning quick and problem-free – and at the same time our “midget” will still find space even in the smallest electrical cabinets thanks to the side-mounting option. Simply everything matches: the power and the price.

Typical applications:

Pumps, fans, advertising boards, barriers, door drives, vending machines.

Its strengths in brief

  • The contactor-like design enables the unit to be installed easily in line with EMC guidelines with familiar handling
  • Operation on a 30 mA RCD in conjunction with a version with integral Type B filter enables the converter to be used directly in the domestic/commercial sector
  • Cooling without fans yet with a compact design for noise-sensitive applications
  • Can be used throughout the world thanks to the option of connecting to 230 V and 115 V single-phase networks
  • A variety of commissioning options with control panel or software tool enables the unit to be easily commissioned at the customer’s request
  • Attractively priced drive design due to high overload capability
  • Compound braking for controlled rapid braking
  • Increased system availability due to automatic restart after mains failure or operational fault
  • Converter can be switched on to a running motor without causing damage
  • A variety of options for the frequency setpoint support widely differing control philosophies.
  • Bus communications interface (USS) in every converter enables the unit to be incorporated into a networked automation system by simple means
  • Directly suitable for use on IT networks thanks to removable “Y” capacitor
  • Clip-on, optional control panel
Protection functions:

All necessary protection and overload functions are already incorporated as standard. For example, fast current limit (FCL) – the ultimate integral protection for all eventualities.
