Product Short Description
Product Name: Single-Pole Soft Starter Bypass Contactor
Overview: The GHISALBA GHOPC-410 B (material code AAV66870) is a single-pole bypass contactor specifically designed for soft starters. It shorts the internal thyristors after soft starting completes, reducing conduction losses and heat generation. It is NOT intended for breaking short-circuit currents and has no arc-quenching capability.
Description
Technical Specifications:
- Main Contact Configuration: Single-pole Normally Open (1P NO)
- Continuous Rated Current (Ith): 410 A
- Rated Insulation Voltage (Ui): 690 V AC
- Rated Impulse Withstand Voltage (Uimp): 6 kV
- Coil Control (Built-in Rectifier Bridge): AC 230 V 50 Hz / DC 196 V
- Coil Protection: Built-in varistor for surge absorption
- Connection Method: Copper busbar bolt connection
- Protection Rating: IP20 (panel/cabinet interior mounting)
- Standards: IEC 60947, CE certified
- Single Unit Net Weight: Approximately 1.1 kg (3 units = standard 3-phase replacement kit)
Key Features:
- Extremely low contact resistance for minimal heat generation during long-term high-current operation
- Integrated copper plate terminals for high-power soft starter main circuits
- Coil with built-in rectifier — universal AC/DC drive
- Modular single-pole design: only the damaged pole needs replacement, reducing maintenance cost
- Widely paired with Schneider ATV series high-power soft starters
Application Scenarios: Soft starter thyristor bypass in 3-phase systems (requires 3 units for a complete set), variable frequency drive DC bus pre-charge resistor bypass, and other steady-state conduction applications where frequent switching is not required.
Working Principle: After the soft starter completes its ramp-up sequence, the GHOPC-410 B closes to short the thyristors, diverting main current through the low-resistance contact path. This eliminates thyristor conduction losses and reduces system heat generation.
