Overview
The Diesel Generator Set - YUCHAI BC-YC400D-50 (320 kW / 400 kVA) is a 400 kVA / 320 kW standby diesel generator set, built around a YC6MK480L-D20 engine and open type configuration. It delivers 50 Hz, three-phase four-wire, at 110/208 V – 277/480 V.
This rating is used as whole-plant backup or as on-site prime generation: mid-size industrial plants, distribution centres and infrastructure projects whose base load exceeds what a compact set can carry. BCP’s Yuchai range spans 23 to 3750 kVA with Yuchai power, intended for standby duty and for extended running depending on how the fuel and cooling system is specified.
Typical applications
- Mid-size industrial plants
- Distribution centres and cold storage
- Mining and quarries
- Infrastructure projects
- On-site generation for remote plants
Standby and prime ratings
The standby rating (400 kVA / 320 kW) is what the set delivers during a grid outage, for a limited number of hours a year and without sustained overload. The prime rating (PRP) allows continuous duty with varying load. Sizing starts from the real load in kW, corrected by power factor, with headroom left for motor starting.
Frequently asked questions
What is the difference between standby and prime?
Standby is the power available in an emergency, limited to a set number of hours a year; prime is what the set can sustain continuously with varying load. A set sized for standby should not be used as prime generation without re-checking the duty.
What voltage and connection does the BC-YC400D-50 deliver?
It is offered at 110/208 V – 277/480 V, three-phase four-wire, 50 Hz. Final nameplate voltage is fixed at order stage according to the site network and the transfer arrangement.
Can it run in parallel with another set or with the grid?
Yes, with a synchronising panel and coupling protection. Parallel operation requires agreeing load-sharing modes, protection settings and the transfer sequence before the panel is built.
