Overview

The ABB M15CLF100-22-WMBQTMA is an encapsulated molded current-limiting fuse designed for medium-voltage applications requiring precise fault current interruption. Rated at 8.3kV nominal voltage and 100A continuous current, this fuse provides reliable protection in industrial electrical systems where fault currents exceed the interrupting rating of standard fuses. The encapsulated molded construction ensures environmental resistance and eliminates the risk of arcing or contamination, making it suitable for harsh operating conditions. The WMBQ option includes a wall mounting bracket with parking stands and quick-release hold-down straps, enabling secure installation on vertical surfaces while allowing easy access for maintenance. The TMA tilt mounting adapter bolts to the bottom of the WMBQ bracket, permitting installation at up to 60 degrees for optimal space utilization or alignment with existing equipment. This combination of mounting flexibility and robust construction makes the M15CLF100-22-WMBQTMA ideal for switchgear, motor control centers, and distribution panels in commercial and industrial facilities. Key applications include protecting transformers, motors, and feeders in systems where fault currents may reach 100kA RMS symmetrical. The fuse’s encapsulated design prevents moisture ingress and reduces the risk of phase-to-phase or phase-to-ground faults during operation. With a compact footprint and compatibility with standard 8.3kV class equipment, this fuse integrates seamlessly into existing ABB and third-party systems. The quick-release straps simplify fuse replacement, minimizing downtime during maintenance or fault events.
