What is a 63A 3P Breaker?

A 63A 3P breaker is a three-pole circuit breaker designed to handle 63 Amperes of current. It protects three-phase electrical systems from:

• Overloads (excessive current)

• Short circuits (sudden current surges)

• Electrical faults (preventing fires & equipment damage)

Unlike single-pole (1P) or double-pole (2P) breakers, a 3P breaker simultaneously disconnects all three phases, making it essential for industrial motors, HVAC systems, and large machinery.
