Manual Motor Starters

Product catalog summary

Technical Specifications
The manual motor starters comply with standards IEC/EN 60947-2, IEC/EN 60947-4-1, IEC/EN 60947-5-1, and IEC/EN 60204. They offer a degree of protection of IP20, which increases to IP40 when terminals are covered. The operating temperature ranges from -25°C to +60°C, with storage temperatures up to +70°C. The devices have a mechanical and electrical endurance of 100,000 operations and are resistant to shocks and vibrations as per IEC standards. The rated insulation voltage is 690V, with an impulse withstand voltage of 6kV.

Main Circuit
The connection terminals are designated as 1-L1, 3-L2, 5-L3, 2-T1, 4-T2, and 6-T3. The terminal capacity for solid cables is 0.75 to 10 mm² and for flexible cables is 0.75 to 6 mm². The maximum operational voltage is 690V with a rated frequency of 50-60 Hz. The rated current ranges from 0.1 to 18 A for GHA18 models and up to 32 A for GHA32 models. The devices are sensitive to phase failure and have a trip class of 10.

Accessories
Auxiliary contact blocks are available for side and frontal mounting, with various configurations such as 1NO + 1NC and 2NO. Undervoltage and shunt releases can be fitted on the left side of the motor starter, but not simultaneously. Enclosures are available in IP41 and IP55 ratings for wall and flush mounting. Additional accessories include signal lamps, emergency stop pushbuttons, neutral links, 3-phase connecting busbars, padlock attachments, terminal blocks, and adaptors for combined mounting with contactors.

Ordering Information
Each model has specific ordering codes, with detailed specifications for short-circuit breaking capacity and maximum back-up fuses required. The document provides a comprehensive list of models, their settings, and corresponding ordering codes.
