CI-tronic™ Soft starters Type MCI 12CH/15CH/25CH

The MCI CH soft starters are designed for starting/stopping of hermetic compressors for residential pumps, refrigeration and A/C units.

The soft start ramp-up time is ﬁxed to ensure lubrication and optimal start current reduction.

Features • Control voltage 208-240 V AC

• Automatic detection of missing phases

• LED Status indication

• Automatic adaptation to 50/60 Hz

• Easy and quick installation

• Built in varistor protection

• IP 20 protection

• Compact modular design

• DIN rail mountable

• Ramp-up time max 0.2 s (factory set-up)

• EN 60947-4-2
