Littelfuse MPU-32-02-00 is a compact protective relay with multiple features. It operates at frequencies of 50, 60, or ASD. With conformal coating, it provides standard protection. The relay contacts are 3 Form C (N.O./N.C.) designed for fail-safe/non fail-safe operation. This device supports IEEE device numbers 37 - 38 - 46 - 49 - 50 - 50G - 50N - 51 - 51G - 51N - 66 - 74 - 86 - 87. It can be reset using either a front-panel switch or a remote N.O. contact. Harmonic filtering is standard, and it offers GF trip time ranging from 0.0 to 100.0 seconds. It operates with an AC supply voltage of 65 - 265V and a DC supply voltage of 80 - 275V. Communication options include RS/TIA-232 and DeviceNet. It also features an analog output current of 4 - 20mA, a GF trip level range of 5 - 100% of CT-Primary Rating, and a single or up to 25 temp sensor configuration with MPS-RTD. Additionally, it has 1 digital input.
