FAQs

The MDL3800FK02P04S02Z03 is designed for Series C molded case panel integration with optional line and load terminals. For installation, connect primary power to the MT terminals as configured and use the TA801MA-compatible terminations when required. The device supports a rear shunt trip (12-24 Vac/dc) with a left pigtail, enabling remote operation and quick emergency shutdown in automated lines.
Key ratings include an 800 A continuous current rating, 600 Vac and 250 Vdc operating voltages, and interrupt ratings of 65 kAIC at 240 Vac and 50 kAIC at 480 Vac. It uses an electronic LSI trip mechanism, providing precise protection for motors, drives, and other heavy loads common in manufacturing environments.
Yes, the device offers a rear shunt trip option rated at 12-24 Vac/dc with a left pigtail. This enables remote trip signals from control systems or safety interlocks, improving machine safety without requiring manual operation on the MCCB. Ensure remote wiring adheres to control system voltages and surge protection requirements.
The unit supports optional line/load terminals and is designed to work with StrandAble terminal solutions. TA801MA terminals are noted for compatibility, providing reliable, easy-to-install connections. These features simplify retrofits and upgrades in existing panels and support clean, modular wiring approaches in automated systems.
UL Listed certification confirms compliance with recognized safety standards, reducing regulatory and audit risk in manufacturing environments. The device’s high interrupt ratings, robust insulation, and Remote Trip options align with safety programs for machine protection, enabling safer startup/shutdown sequences and improving overall plant reliability.
