Selection Guide

3.1 代表的な用途

Direct starting and protection of small three-phase motors (1.5kW/400V)

Control of pumps, ファン, compressors and industrial automation equipment

Replacement of traditional “fuse + contactor” combinations to save space and cost

Applications requiring manual control and reliable motor protection

3.2 Selection Steps

Verify motor rated current: within 2.5~4.0A adjustable range
Check motor power: ≤ 1.5kW (400V AC-3)
Confirm system voltage: ≤ 690V AC, 50/60Hz
Evaluate short-circuit current: system short-circuit current ≤ 50kA (400V)
Installation space: reserve 45mm DIN rail width
Ambient conditions: temperature -25°C ~ +55°C, no excessive vibration or corrosive gas

3.3 Setting & Operation Notes

過負荷保護: set to 1.0~1.1 × motor rated current (within 2.5~4.0A)

Ensure reliable phase failure protection for all three-phase motor applications

Use isolation function: safe electrical isolation after shutdown for maintenance

Can be used with contactors for remote control and automatic protection

Cross-Brand Replacement Models

Application Notes
Thermal-magnetic characteristics: Class 10A is intended for standard squirrel-cage motors; not recommended for special loads (例えば, 変圧器, capacitors)
Phase failure protection: Trips within 2~5 seconds if any phase is lost, effectively preventing motor burnout
Fuse-free design: Eliminates external fuses, reduces cost and maintenance; ensure line short-circuit current ≤ 50kA
Free tripping mechanism: Forces tripping under overload/short-circuit even in ON position, ensuring safety
Temperature compensation: Protection characteristics stable over ambient temperature range -25°C ~ +55°C
