ABB GAF460-10 DC Contactor  

1. Key Parameters

• Product Model: GAF460-10
• Product Series: ABB GAF-Series Industrial Low-Voltage DC Contactors (DC Circuit Control)
• Core Function: 1-pole main contact (NO); DC arc suppression; DIN rail mounting; compatible with DC motor drives/battery systems.

2. Core Features

• DC Arc Suppression: Built-in arc-extinguishing structure prevents electrical arcing (a key hazard in DC circuits), ensuring safe breaking and long contact life.
• High Reliability: 60A continuous current rating and 1.5kA breaking capacity adapt to most low-voltage DC load scenarios (e.g., 20kW DC motors).
• Compact Design: 70×95×65mm size fits dense DIN rail layouts in DC control cabinets, saving space.
• Wide Compatibility: Supports 24V/48V DC coils, matching common DC system power supplies (e.g., battery banks, DC power modules).

3. Application Fields

• New Energy Systems: Controls battery discharge circuits in solar energy storage systems or electric vehicle (EV) charging piles.
• Industrial DC Drives: Switches power supply for DC motors in cranes, conveyors, or material handling equipment.
• Backup Power: Manages DC backup power loops (e.g., UPS battery circuits) in data centers or emergency lighting systems.

4. Precautions

• Compatibility: Match coil voltage to DC system power (24V/48V); do not exceed 60A continuous current or 440V rated voltage.
• Installation: Ensure proper ventilation (min 5mm clearance) to avoid overheating; torque power terminals to 2~2.5 N·m (copper cables).
• Maintenance: Inspect main contacts annually for arc wear; replace if contact erosion exceeds 0.5mm; clean coil connectors to prevent poor energization.
• Spare Parts: Use genuine ABB GAF460-10 units—non-genuine contactors lack effective arc suppression, risking contact welding or circuit fires
