ZSN4-315-092 315 kW 380V Rated Current 770A Specs

ZSN4-315-092 is a high-performance DC Motor (hoisting/metallurgy) built by Xi'an XIMA Electric (Group) Co., Ltd., rated 315 kW, voltage 380V, rated current approx. 770.0 A, protection IP23 / IP44, efficiency —. Based on real sample data, this guide covers model meaning, specifications, selection and FAQ.

1. What ZSN4-315-092 means: series ≠ model

Many buyers treat “ZSN” as a full model — a common mistake. The series code is only a product family; a complete motor model must include the frame size and pole/spec code. For ZSN4-315-092:

• ZSN — series code, DC Motor (hoisting/metallurgy);
• 315 — frame size (center height in mm);
• spec code — distinguishes power, speed and electrical design.

Only ZSN4-315-092 is the unique, orderable model; “ZSN” alone cannot pin down the spec.

2. Key specifications (real sample)

Note: above are library sample parameters; final values per XIMA datasheet and order confirmation.

3. Technical features

• Wide stepless speed range with high starting torque.
• Compensating and interpole windings give reliable commutation and overload ability.
• Rugged IP23/IP44 construction for metallurgy and hoisting loads.
• Pairs with thyristor DC drive for constant-torque / constant-power operation.
• Long-life brushes and commutator with low sparking, easy maintenance.

5. Typical industries

6. Standards

• GB/T 6656
• IEC 60034-1

7. Ordering notes

• State full model, power, voltage, speed/poles, mounting (IMB3/B5/V1) and protection/Ex level.
• Specify environment (temp, altitude, humidity, medium) and starting method (DOL/VFD/soft-start).
• Request special shaft, dual shaft, tachogenerator, encoder or brake at order time.
• Confirm cooling (IC411/IC416/IC611/IC81W) and matching cooler / inverter brand.
• Allow 10–15% power margin; confirm lead time, warranty and site commissioning scope.

8. FAQ

Q: What is the difference between “ZSN” and ZSN4-315-092?

A: “ZSN” is only the DC Motor (hoisting/metallurgy) family code; ZSN4-315-092 adds frame and spec code and is the orderable model.

Q: What are the rated power and current of ZSN4-315-092?

A: Sample rated power approx. 315 kW, voltage 380V, rated current approx. 770.0 A; final per datasheet and order confirmation.

Q: Is frame 315 large? Any mounting notes?

A: 315 mm is a medium-large frame; bolt pattern per IMB3, foundation must be leveled, on-site guidance recommended.

Q: What is the protection / Ex level?

A: Protection IP23 / IP44; for hazardous areas confirm the Ex mark and gas group.

Q: Why does efficiency — matter?

A: Higher efficiency cuts running cost and heat, ideal for continuous duty with short payback.

Q: How is ZSN4-315-092 cooled?

A: Cooling IC06 / IC17; keep cooling medium/air path clear under full load.

Q: Can it be customized?

A: Yes — voltage, speed, shaft, mounting, sensors and coating; state requirements at order.

Q: Where to get quote and datasheet for ZSN4-315-092?
