Busch-Jaeger haarakiskokisko 3-napainen 10 moduulia 63 A 10 mm² (4TQA750196R1012)

This fork busbar from Busch-Jaeger streamlines three-phase distribution in consumer units by connecting up to ten DIN rail devices with a single component, eliminating the need for individual wiring links. The fork connection design allows installation without removing the busbar from the rail, saving time during assembly and future modifications.

Highlights

• 3-pole configuration for three-phase supply
• 10 module pitch (175 mm) covers ten standard 17.5 mm devices
• 63 A rated current with 10 mm² copper conductor
• Fork terminals for quick, secure connections
• Self-extinguishing thermoplastic insulation

In daily use

The busbar mounts directly onto a DIN rail and feeds miniature circuit breakers, residual current devices, or RCBOs. Its grey insulation provides clear phase identification and protects against accidental contact. The fork terminals grip the device terminals firmly, maintaining a reliable connection even under vibration.
