Now Moeller Offers Even More xStart

[picture of PKZMx units] Just 45mm wide, PKZM0 motor protection circuit breakers in Moeller Electric's popular xStart range are now available in versions to switch motors rated at up to 32A. This provides an ideal basis for compact, dependable and cost-effective fuseless starting solutions for the vast majority of motors used in commercial and industrial applications.

Moeller has also added PKZM01 pushbutton operated breakers with ratings up to 25A to the range, alongside models with the more usual rotary operators. This is a great help, for example, where they may be used by operators wearing gloves, the pushbutton versions are complemented by new accessories that include IP40, IP55 and IP65 enclosures, and an emergency stop pushbutton.

All of the new PKZM0 breakers have enhanced short-circuit ratings – 150kA for models with rotary operators and ratings up to 12A, and 50kA all other models. These increased ratings mean that the need for inconvenient external current limiters is now virtually eliminated, cutting wiring time and saving panel space.

The PKZM0 motor protection circuit breaker range includes models with ratings from 0.16A to 32A. All types provide short-circuit and adjustable overload protection which fully meets the requirements for Type 1 and Type 2 co-ordination according to IEC 60947-4. For larger motors, similar functionality is offered by Moeller's PKZM4 motor protection circuit breakers, which are available with ratings up to 65A. The versatility of the PKZM range is further extended by the availability of a large selection of accessories. Compatible with both PKZM0 and PKZM4 products, these include shunt and under-voltage trips, front-and side-mounting auxiliary contacts, and door coupling handles.
