Product Description
The Allen-Bradley 150-B135NBDA is a 135-Amp, 460VAC, open-enclosure, solid-state smart controller from the SMC family, requiring a heatsink and offering variable power output from 5 to 100 HP across three phases with dual, load-dependent frequencies (50-60 Hz input). It features a 100-240VAC control voltage range, soft stop, slow speed with braking, a serial port for HMI and communication modules, an integrated keypad with backlit LCD (Escape, Select, Up/Down, Enter keys), enhanced diagnostics including overload/underload and over/undervoltage protection with fault reporting, and UL, CSA, IEC, and NEMA certifications, requiring a dry, ESD-free environment.
Is Your Device Showing These Signs?
The Allen Bradley 150-B135NBDA commonly experiences issues such as thermal overload trips due to incorrect FLA settings or excessive ambient temperature. Contactor failure, stemming from coil burnout or worn contacts, is a frequent problem. Diagnose nuisance tripping by verifying proper motor inrush current and adjusting the dial accordingly. Inspect auxiliary contacts for damage or wear, and confirm proper wiring connections to prevent operational faults. Replacement of the entire unit is necessary when internal components fail or damage is extensive.
