FAQs
Install with the D-End top terminal box accessible for routine wiring checks, ensuring adequate clearance for heat dissipation and safe maintenance. Use compliant flameproof cable glands and match to the Exdb protection class. Confirm 315 frame mounting alignment with existing base plates and ensure cooling air can circulate freely in facilities with restricted spaces.
Exdb flameproof protection prevents ignition in explosive atmospheres, enabling safe operation in gas groups IIB. IP55 guards against dust ingress and water jets, preserving winding integrity and bearings in tough environments. Together they support regulatory compliance, reduce failure modes, and extend maintenance intervals in chemical, petrochemical, and mining applications.
Yes, this motor is designed for 50 Hz operation with IE2 efficiency. Full-load efficiency is about 95.1%, and partial-load performance remains strong at 75% and 50% of rated load (95.1% and 94.5%, respectively). Its 4-pole design supports steady torque and predictable thermal behavior for continuous-duty applications.
Industries including chemical processing, oil and gas, mining, and cement rely on Exdb-protected motors for hazardous areas. Applications span pumps, fans, conveyors, mixers, and other continuous-duty equipment where reliability, safety, and energy efficiency drive uptime and compliance with stringent standards.
A robust cast-iron frame and IC411 insulation withstand demanding conditions, reducing unplanned outages. IP55 and Exdb protection minimize field repairs in dusty or damp environments, while IE2 efficiency lowers energy costs over the life of the motor. The 315 frame and D-End top terminal box streamline installation and serviceability, shortening maintenance cycles.
