MOTOR PROTECTION AND CONTROL
NewElec designs and manufactures a wide range of superior electronic motor protection relays for both local and International markets. NewElec's goal, for the past 31 years, has been to exceed the expectations of every client by offering quality products, outstanding customer service and greater value, thus optimizing system functionality and improved operational efficiency.
As experts in motor protection, NewElec is involved in every stage of the client's selection of the required protection relay offering ongoing functional and technical support. Our R&D division is continually designing the most up to date motor protection products to meet customer requirements.
N Series Relay
The N Series electronic motor protection relays are housed in a versatile enclosure which caters for door mount, chassis mount or C.T. module mounting.
Protection features include selectable thermal curves (Class 5 - 30) with thermal pre-loading to match the safe HOT and COLD stall times of the motor during operation.
Designed to IEC 60255-8, the N Series provide overload protection for cyclic or sustained loads, as well as unbalanced current, single phasing, earth leakage and earth fault protection, with an option to transfer trip to incoming MCCB to prevent contactor opening on high energy faults, ensuring type 2 co-ordination.
The NewCode relay is an ISO 9001:2000 compliant, locally designed and manufactured three phase electronic motor protection relay.
The relay is fully configurable with the aid of free front-end software or a man-machine interface unit (MMI).
An on-board data base stores fault and event records, which are date and time stamped. The front-end data recorder and spectrum analyzer can be used to monitor motor performance or to detect harmonics up to the 9th harmonic of any three phase currents.
Thermal overload, over and under voltage and voltage symmetry protection as well as frequency, power factor and power dissipation measurement are basic features OFFERED by the relay.
GA Series Relay
Pioneers of the harmonic suppression circuit characteristics, the GA Earth Leakage protection relay enables more sensitive earth leakage protection of high kilowatt motors started direct-on-line as well as variable speed drive applications without nuisance tripping.
Available in diverse configuration options, including Latched or Non-latching main trip contact, Fail-safe or Non Fail-safe options, as well as 110V-220V or 380V-525V A.C. auxiliary supply voltages.
The trip contact current rating is a sturdy 6A at 220V and 3A at 525V A.C. A latched 'contactor trip' change-over contact can only be reset by pressing the control panel mounted pushbutton.
The ProLoc II relay is a micro-controller based precision instrument with protection, control logic, starter logic and communication functions. It is designed for the low voltage motor protection market and is available in different current models. The current transformers are integrated into the relay while the core balance current transformer is external. External interposing current transformers can be used to extend the operating range from 100 to 400A.
The relay is fully configurable with the aid of front-end software or a man machine interface unit (MMI). Event records can also be down loaded via the MMI (iRDA -infra red link) for further analysis.
