circuits up to 690V AC and 220V DC,
and are available in 3-pole and 4-pole
configurations. They feature integrated
electronically controlled coil, wider
control voltage range with four coils,
reduced dimensions of up to 30%
to save space, reduced coil energy
consumption of up to 80% and are
equipped with low voltage inputs.

OVERLOAD RELAYS

Our range of overload relays from
ABB offers superior protection for
the motor by monitoring the current
flowing in the circuit and are Phase
