General Information
The new Bulletin 140M Motor Protectors provide Class 10 overload protection as well as current limiting short-circuit protection for individual motor loads. They are approved for use as circuit breakers per IEC 947-2 for applications outside of North America, but in the United States and Canada, they are UL/CSA listed as Manual Starters with the optional approvals for Motor Disconnecting and Group Motor applications. Additionally, these new devices are UL/CSA listed as Self-Protected (Type E) Manual Combination Starters — eliminating the requirement for additional short-circuit protection in many applications. This reduces both panel space and cost in multi-motor installations and eliminates the restrictive NEC/ CEC rules that pertained to Manual Starters used in Group Motor applications.
The following information is provided to aid in proper system design utilizing the capabilities of the new Bulletin 140M Motor Protectors in North American applications. Please be sure to follow all local and national codes for your particular installation.
