Our motor circuit protectors provide short-circuit protection for individual motor loads and are available for a wide range of motor sizes and installation types. They can be combined with our NEMA and IEC motor starters, overload relays, and contactors.
140MT Motor Circuit Protectors
Our Bulletin 140MT Motor Circuit Protectors (D9N version), rated up to 40A, can be applied in combination with Contactors and Overload relays.
140MG Motor Circuit Protectors
Our Bulletin 140MG Motor Circuit Protectors can provide a disconnecting means for motor branch circuit, branch-circuit and short-circuit magnetic protection, and manual switching. These devices are rated from 3...1200 A. In North America, electrical codes require that an individual motor branch circuit be protected by a UL/CSA Listed fuse, circuit breaker, or self-protected combination motor controller.
