Slimline Solutions Lead to a New Era in Motor Management

• The sophisticated construction and the latest technology of materials of Allen-Bradley’s new circuit breakers 140M result in outstanding features and performance.
• High and effective current limiting and an extremely fast disconnection time result in an excellent short circuit breaking capacity, allowing shortcircuit co-ordination Type 2 to be achieved automatically with no oversizing of contactors.
• This means you can fit more into your panels with less wasted space.

Outstanding flexibility due to consistent MCS modularity

• Two basic types of circuit breakers for 25 A and 45 A are available in High Break or High Break PLUS versions (Size 1 and 2). Three protection characteristics – Motor Protection (precise overload protection), Starter Protection (short circuit protection only) and Transformer Protection (for high inrush current) – allow the selection of the best suited circuit breaker for the application.
• As with all other MCS components, the new circuit breakers 140M are electrically and dimensionally integrated into the system, this facilitates assembly, handling and logistics.
• The comprehensive range of uniform accessories including the unique front mounted trip/auxiliary contact gives a greater variety and flexibility in signalling and supervising.

The breaking champion • The new circuit breakers 140M set new standards in breaking capacity and current limiting. This results in these benefits: No back-up fuses No current limiters No oversizing of contactors. • The new circuit breakers 140M can be installed even closer to supply transformers.

The money saving champion With the new circuit breakers 140M you get a superior price/performance ratio compared to other solutions. No oversizing of contactors necessary, this makes starters more economical. No need for costly integrated starter solutions thanks to the consistent modular concept. Compact starters lead to smaller, more economical control cabinets and panels.
