MA- Series Three Phase Adjustable Trip UL508 listed Miniature Circuit Breakers/ E137938 Manual Motor Controllers CAN/CSA-C22.2 No.14 certified The MA was designed to handle the high inrush loads of 3 phase transformers, power supplies, motors, etc. The MA protects wiring and equipment from damage caused by the three major classes of over-current, yet greatly reduc- es the number of nuisance trips in high Type Designation starting and inrush current circuits. MA RT An IEC device with excellent ratings under (a) (b) (c) (d) a UL listing at 480Y/277V (including group ratings) and at 500V under international (a) = MA - Manual Motor Controller standards, the Altech/ABL Sursum MA (b) = Rated Current provides short and long term cost effective (c) = U - US Housing circuit protection for USA and/or export applications. The short term advantages (d) = Blank - Standard Terminal include: (1) adjustable thermal trip allows RT - Ring-tongue Terminal finalization of initial designs before procurement of the load equipment is Voltage Rating 480Y/277VAC complete (2) snap-on mounting for readily AIC (Interrupt Capacity) 0.16A-2.5A: 42kA 4.0A-16A: 14kA 20A-40A: 10kA available, internationally standardized DIN Rail saves panel layout design time as well Standard Short Circuit Withstand Rating 0.16A-2.5A: 42kA 4.0A-16A: 14kA as installation and change labor (3) large (UL/CSA Ratings) cage-clamp terminals with screws suitable Group Short Circuit Ratings see above to power screwdrivers, simplifies and (UL/CSA Ratings) speeds wiring (4) convenient switched Typical Life 6000 on/off operations with 2xRC disconnect during factory testing and/or initial start-up saves time and aggravation.
