TPB1-63 AC Miniature Circuit Breaker(MCB) for Load Safety
Breaking capacity(TPB1-63:3kA;TPB1-63H:4.5kA;TPB3-63:6kA;TPB3-63H:10kA)
TPB1-63 Miniature Circuit Breaker (MCB) is designed for AC 50/60Hz electrical circuits with a rated voltage up to 400V and a rated current up to 63A. It provides reliable overload and short-circuit protection, and can also be used for infrequent circuit switching under normal Operating conditions.
It is widely suitable for residential distribution boards, commercial premises, industrial control panels, and high-rise building electrical systems.
Standard: IEC 60898-1

Miniature Circuit Breaker current performance is temperature-dependent. Ambient temperature means the temperature inside the enclosure(distribution box/switch cabinet) at the installation location. Refer to the rows in the table for the corresponding reference temperatures.Product standard: GB/T 10963.1, IEC 60898-1(household standard)
