Circuit breakers for harsh operating environments

1st Quarter 2016 Electrical switching & drive systems & components

The addition of two new models to the WEG MPW range of motor protection circuit breakers will offer customers a broader range from which to select the most appropriate protection for electric motors. All motor protection circuit breakers in this range are manufactured in accordance with IEC 60947 and UL 508 international standards, giving absolute assurance in terms of operational parameters and quality.

These devices are compact and modular, allowing space saving within the electrical panel itself. This means that the panel can be smaller and more components can be included in the panel. Engineered to withstand harsh operating conditions, they are robustly constructed for optimal reliability.

The range facilitates the protection of a wide range of electric motors from 0,16 to 100 A. The range has both thermal magnetic versions, which provide protection against any potential short circuit and overload conditions, and magnetic only versions, which provide protection against short circuits. Use of the thermal magnetic device reduces the amount of components required when manufacturing a motor control centre and this can translate into a significant cost saving. The magnetic-only version allows the use of electronic overload protection devices which can reduce costs further.

This 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.
