Yuanky

Yuanky industrial power distribution and control for panel builders and OEMs

Yuanky supplies a focused portfolio for low-voltage switchboards, MCCs, and machine panels. The range covers selective protection on DIN rail, dependable control circuits, and accessories that shorten commissioning time while meeting EU conformity expectations.

Where Yuanky fits in a modern panel

• Main and sub distribution in commercial and light industrial sites
• Motor feeders and control power in conveyor lines, HVAC, pumping, and packaging cells
• Retrofit programs that require documented coordination data and predictable lifetime

Core categories

• Logic and control devices for starters, interlocks, timing, and supervision: Yuanky automatics and control
• Protective devices for feeders and final circuits, with accessories for labeling and busbar: breakers and DIN modular devices

Engineering selection criteria

Protection and selectivity

• Breaking capacity Icn and service Ics versus fault level at installation point
• Trip curves B C D for final circuits and discrimination with upstream breakers or fuses
• Temperature derating inside enclosed boards, terminal torque, cage vs clamp type
• IP rating, pollution degree, creepage and clearance for the environment

Control and automation

• Coil voltage variants and tolerance for warm panels, inrush and holding power
• Utilization categories AC 3 AC 4 for motor duty, mechanical and electrical endurance
• Auxiliary contact layouts for PLC feedback and interlocks
• Timing and monitoring functions on delay, off delay, asymmetry, phase loss, undervoltage

Coordination for motor circuits

• Type one vs type two coordination with upstream protection
• Short circuit withstand of contactor starter assembly
• Overload class matching to motor thermal profile and duty cycle

Panel design and documentation checklist

1. Single control voltage strategy 24 V AC or DC to reduce SKUs and training
2. Terminal and wire marking aligned to drawings and asset labels
3. Selectivity tables attached to project pack, including heat rise assumptions
4. Routine verification records dielectric tests, torque logs, functional tests
5. Spares list by board coils, auxiliaries, breaker poles, labeling kits

Commissioning and maintenance

• Record pickup and dropout measurements for critical relays and contactors
• Validate breaker trip using secondary injection where applicable
• Schedule quarterly inspection for hot spots, loose terminals, and device age counters
• Keep a quarantine bin for removed protective devices to avoid accidental reuse
