FAQs
The M3BC 355SMB 2 features IP55 protection and an IC416 insulation class, designed to withstand dusty, humid or challenging industrial environments. Its 2-pole, 355 frame in cast iron provides a robust mechanical interface, making it suitable for long-running pumps, fans, and conveyors while maintaining performance in ambient temperatures up to 40 °C.
This motor is well-suited for general-purpose drives in manufacturing lines, including pumps, fans, and conveyors. The 3-phase squirrel cage design with S1 continuous duty supports steady operation, while the IP55 rating protects against dust and moisture, enabling reliable service on open or semi-enclosed equipment.
The 2-pole design provides a straightforward, high-torque startup suitable for many industrial loads, with simple installation aligned to standard 355-frame bases. It supports efficient operation at typical line frequencies and simplifies drive integration, reducing commissioning time and facilitating predictable rotational speed for process control.
With an altitude rating up to 1000 m and an ambient temperature allowance of 40 °C, the motor is designed for locations with elevated heat load and limited air cooling. Insulation class ICLF and IC416 protection help prevent insulation breakdown, while the cast-iron frame maintains structural integrity under thermal expansion and mechanical stress.
The M3BC 355SMB 2 combines rugged construction with a simple mechanical interface, which reduces maintenance frequency and downtime. Its durable frame and protective IP55 rating translate into lower replacement costs and longer service life, delivering a favorable total cost of ownership and faster payback on automated plant modernization projects.
