KRAUS&NAIMER Full Series Model Recommendation Guide

Mainstream models are classified into Control Switches, Isolating Switches and Special-purpose Switches, covering various current ratings, pole configurations and working conditions, all adopting brand mature high-performance double-break contacts and modular design concepts.

1. CA Series (コントロール & Load Switches, 10～32A)

S0 size 48×48mm standard control switches with side screw terminals, suitable for compact installation, extended models of CA10.WAA345EF.

Model Explanation Example: CA10.A291-600FT2

CA10: S0 outline size, 20A rated thermal current

A291: 4-pole 2-position cam logic, full-pole on-off

600: Standard auxiliary contact configuration

FT2: Lockable black knob to avoid accidental operation

2. CG Series (Compact Heavy-duty Control Switches, 10~40A)

Same overall dimension as CA series, equipped with front wiring terminals, more convenient for standard control cabinet installation.

3. CH Series (Instrument & Precision Control Switches, 10~40A)

Specially developed for instrument measurement and precise signal switching, optional gold-plated contacts, applicable to low-current high-precision control occasions.

4. KG Series (Safety Isolating Switches, 10～63A)

Enclosed safety isolating switches with excellent short-circuit resistance, preferred main switch and maintenance switch for machine tools and power distribution cabinets, IECに準拠 60947-3.
