01 February 2019 | Web Article Number: ME201913364
MAGNET’S portfolio of space saving Eaton motor control and protection devices offer motor starting and protection solutions in diverse industries, including mining, oil and gas, pulp and paper, OEMs, the automotive sector and in general utilities.
“This range - which encompasses contactors, circuit breakers and overload relays - has been designed for easy installation and simple set-up, increased accuracy, greater visibility into the motor status and a higher degree of protection,” said Magnet Group Managing Director Brian Howarth.
“Eaton motor control and protection products efficiently meet the demands of challenging applications, including motor control centres, field starter panels and heavy-duty pumps, as well as conveyors, fans, pumps and compressors.”
He said the group hosted Eaton roadshows around the country in October, to offer clients an opportunity to interact with product specialists and to engage with products prescribed for their facilities’ specific applications. “On display were Eaton products from their motor control range, along with comprehensive Eaton solutions for automation, circuit protection and power distribution.” DILM contactors for utilisation category AC-1/400V are rated for normal switching duty for 3 pole, non-motor loads. Operating characteristics include non-inductive and slightly inductive loads and electrical characteristics for switch on and switch off are 1 x rated operational current. Typical applications for this range are for electric heat.
DILM contactors the AC-3/400V utilisation category are rated for normal switching duty for AC induction motors. Operating and electrical characteristics are switch on from stop at up to 6 times the rated motor current and switch off during run, at up to 1 x rated motor current. Typical applications include compressors, lifts, mixers, pumps, escalators, agitators, fan conveyor belts, centrifuges, hinged flaps, bucket-elevator air-conditioning systems and general drives for manufacturing and processing machines
DILM contactors for utilisation category AC-4/400V are rated for the extreme switching duty of squirrel-cage motors. Operating characteristics are inching, plugging and reversing. Electrical characteristics for making and breaking the current are up to 6 times the rated motor current. Typical applications include printing presses, wire-drawing machines and centrifuges, as well as for special drives used for manufacturing and processing machines.
Eaton PKZM and PKE motor protective circuit breakers (0.63 – 63A) offer short circuit and thermal overload protection, to prevent downtime. These devices, with screw connection and pushbutton or rotary switch type controls for manual on and off functionality, are also suitable for use in environments where there is constant or cyclic damp heat. The range also includes overload relays (0.1 – 800A) and soft starters (18.5 – 560kW) and variable speed drives (0.75 – 160kW). Distributors, Magnet, offer a technical and advisory support service throughout the country.
