Switching capabilities of ABB‘s manual motor starters
Manual motor starters from ABB properly switch motors ON
and OFF and protect them in case of overload and short
circuit.
Thus, ABB‘s manual motor starter know-how increases the
reliability and availability of applications thanks to the ex-
tremely quick short circuit cut-off in cases that could cause
motor damage.
ABB motor starter combinations constitute a reliable, cost-
effi cient solution for all your motor protection needs, for
examples in:
• General engineering and plants
• Industries
• Conveyor systems
• Chemical industries including process engineering
• Pharmaceutical industries
• Automation of buildings, e. g. in air-conditionings
• Environmental plants
• Power stations
• Fresh water and sewage plants
• Machine tools

Manual motor starters provide protection against:
• Overload
• Short circuit
• Phase failure
• Undervoltage
Fuseless protection saves costs and space and provides
for quick reaction under short circuit condition, switching
the motor off within 3 ms. It is therefore an easy to handle,
cost effective protection solution.

Manual Motor Starters from ABB
ABB offers a wide range of a manual motor starters provi-
ding highly effi cient motor protection up to 100 A.
The arc breaking capacity of the devices can reach
up to 100 kA depending of the motor starter type used,
without the necessity for any special upstream protection.
Thanks to its design MS116/325 are suitable for industrial
applicatons as well as for domestic installations.
The device-types MS116/325 can be easily coordinated
with the ABB MCB-system, which is used in installations for
touch-proved enclosures and panels.
MS450 to MS497 are your best choice for high power appli-
cations. These models are used to power up large motors
up to 45 kW.
The types MS325 have the lowest “energy let through”-
values on the market in case of short circuits.
This way cables and the wiring are also protected optimal-
ly, providing for even higher safety.
Manual motor starters must be set to the rated motor de-
mand. Higher current is needed at motor start-up. During
the start-up period the manual motor starter will
let the current go through and will not trip, following the
pertaining international standards and curves for motor
start and hold operation.
