FAQs
This motor uses the IMB5 IM3001 mounting class, with a 355 frame and cast-iron housing that fit standard baseplates and foot-mounted setups. Ensure appropriate clearance for cooling, vibrations are minimized with the rigid frame, and verify alignment with your existing drive system. Typical retrofit and new-install workflows benefit from the common mounting footprint and ABB-approved mounting accessories.
The unit is a 3-phase squirrel cage motor designed for continuous S1 duty. It features a 2-pole design suitable for steady torque and reliable operation, an ambient temperature rating of 40 °C, an altitude tolerance up to 1000 m, and a 355 frame size with a cast-iron housing. Electrical configuration uses a standard 3-phase supply with ABB reliability built in.
Yes, the motor carries an IP55 rating, indicating protection against dust ingress to a limited extent and protection against water jets from any direction. This makes it well-suited for outdoor installations, dusty manufacturing floors, and other challenging environments where machinery protection is essential.
With its 355 frame, IP55 protection, and IMB5 mounting, the ABB 3GBC351421-BXG is ideal for continuous-duty equipment like fans, pumps, conveyors, mixers, and material-handling lines in heavy industry. Its durable cast-iron housing and robust insulation support reliable operation in demanding process environments and across Nordic-to-global manufacturing setups.
Expect lower maintenance costs due to a rugged cast-iron frame, IP55 protection, and IMB5 mounting that reduce downtime and ease servicing. The motor’s continuous S1 duty and reliable insulation help maintain consistent output, improving process stability and energy efficiency over time. Finland-origin manufacturing and transparent tariff 85015394 also support smoother import planning and compliance auditing.
