Motor protection for harsh environments

December 2017 Electrical Power & Protection

The WEG MPW range of motor protection circuit breakers offer customers reliable operation in the harsh operating environment found on the African continent. All products in the range are manufactured in accordance with IEC 60947 and UL 508 international standards, giving absolute assurance in terms of operational parameters and quality.

The devices offer the benefit of being compact and modular, facilitating space saving within the electrical panel itself. This means the panel can be smaller, or where necessary, more components can be included in the panel. The WEG MPW range of motor protection circuit breakers are robustly constructed for optimal reliability and facilitate the protection of a wide range of electric motors from 0,16 A up to 100 A. Significantly, the range has both thermal magnetic versions facilitating protection against potential short circuit and overload conditions, as well as magnetic only versions, which provide protection against short circuits.

Use of the thermal magnetic device will reduce the number of components required when manufacturing a motor control centre, which can translate into a significant cost savings. The magnetic only version allows the use of electronic overload protection devices, which can reduce costs further.

The WEG MPW motor protection circuit breaker is available with a full range of accessories including auxiliary contacts, shunt trips, under voltage releases, door mounting handles and free standing enclosures. The devices are certified to Type 2 allowing continuous operation until replaced. This is important in a production-critical environment.
