MA Circuit Breakers & Manual Motor Controllers

Altech MA Three-Phase Adjustable-Trip Miniature Circuit Breakers and Manual Motor Controllers are designed to handle the high inrush loads of 3-phase transformers, power supplies, and motors. The MA devices protect wiring and equipment from damage caused by the three major classes of overcurrent (overload, short circuit, and ground fault) while reducing the number of nuisance trips in high starting and inrush current circuits. The Altech circuit breakers feature an adjustable thermal trip, allowing the finalization of initial designs before procurement of the load equipment is complete. Snap-on DIN rail mounting saves panel layout design time as well as installation and rework/repair costs. Large cage-clamp terminals with screws simplify and speed up the wiring process.
