2P 63A Molded Case Circuit Breaker

When the load demand of the circuit is upgraded to the kilowatt level, ordinary miniature circuit breakers are no longer capable, while large frame circuit breakers appear redundant. The high-quality 2P 63A Molded Case Circuit Breaker developed by SPX precisely fills the protection gap in this critical interval. It is a structurally robust and high-performance "electric traffic police" specially deployed at the entrance of high current channels.With its powerful 63A current carrying capacity and high breaking characteristics, it ensures that in the event of system abnormalities, it can decisively and safely cut off faults, safeguarding the safety of expensive backend equipment and the overall circuit.Features:

The rated current of 63A enables the SPX factory's CE-certified 2P 63A Molded Case Circuit Breaker to provide backbone protection for high-power loads of around 14 kW (under 220V conditions) in single-phase, and to handle the starting surge current of inductive loads such as commercial equipment and motors with ease.It usually has a high breaking capacity, which can safely cut off and withstand strong short-circuit currents caused by lower level faults, prevent the expansion of faults, and protect the integrity of the distribution system.The overload protection current of some industrial grade models can be continuously adjusted within a certain range, achieving precise matching with load characteristics, avoiding misoperation, and improving power supply continuity.
Provide standard trip curves such as C-type and D-type, and users can choose according to the load type (conventional equipment or motor type) to ensure targeted and effective protection.
The 2P 63A Molded Case Circuit Breaker adopts a high-strength and highly flame-retardant insulation shell, with an internal contact system and arc extinguishing chamber optimized for high current breaking. Its mechanical and electrical life far exceeds that of miniature circuit breakers.
The operating handle has moderate force and clear opening and closing positions. Some models are equipped with a trip indicator window, which can clearly display faults and facilitate quick diagnosis of overload or short circuit faults.

As the main switch for entering shops, restaurants, and small offices, or for setting up dedicated protection circuits for central air conditioning outdoor units and large commercial kitchen equipment (such as electric stoves and ovens).
2P 63A Molded Case Circuit Breaker provides two-phase power supply incoming line protection and isolation for small three-phase motor units, welding machines, experimental equipment, etc.
2P 63A Molded Case Circuit Breaker can protect high-power dedicated circuits such as home theater systems, swimming pool equipment, household charging stations (lower power type), or whole house electric heating.
The main switch of communication base stations and outdoor distribution boxes provides superior protection.
