RP-Onesto Miniature Circuit Breaker 3P C63A 4.5kA – DIN Rail, 415V IP20

The RP-Onesto 3-Pole Miniature Circuit Breaker (3P/C63A/4.5kA) protects three-phase low-voltage networks from overload and short-circuit conditions, and provides occasional switching functionality for residential and light commercial electrical installations at up to 63A rated current.

Key Features

• 3-pole (three-phase) protection in a single unit
• Tripping curve C rated at 63A nominal current
• 4.5kA short-circuit breaking capacity
• Mounts on standard 35mm DIN rail
• Indoor IP20 protection rating
