Key Features and Specifications of the Circuit Breaker Switch

The Circuit Breaker Switch, model JCH3-125, is a main switch disconnector designed for reliable circuit isolation in residential and light commercial electrical systems. Rated for a current of up to 125A, this device serves as a critical safety component, providing a visible point of separation to ensure a circuit can be de-energized for maintenance or in case of an emergency. Its design and construction adhere to stringent international standards, including IEC 60947-3, which governs requirements for switches, disconnectors, and fuse-combination units.

This Circuit Breaker Switch is available in multiple pole configurations, including 1-pole, 2-pole, 3-pole, and 4-pole models. This versatility allows it to be deployed in a wide range of single-phase and three-phase electrical distributions systems. The availability of different pole counts ensures that the appropriate level of circuit isolation can be achieved, whether for a simple branch circuit or the main power supply to an entire building, making it a highly adaptable component for various wiring schemes.

A key safety feature of this Circuit Breaker Switch is its integrated contact position indicator. This visual mechanism provides an unambiguous signal to the operator, clearly showing whether the contacts are in the open or closed position. This is a fundamental safety function that helps prevent accidental contact with live parts during servicing. The unit is equipped with a provision for a plastic lock, enabling the application of a padlock to securely lock the switch in the “OFF” position, thereby enforcing a zero-energy state for enhanced personnel safety.

The operational mechanism of the Circuit Breaker Switch is engineered for both durability and clear, decisive action. The switching operation is designed to be robust, ensuring reliable performance over its mechanical lifespan. As a disconnector, its primary function is not to interrupt fault currents but to provide a safe, isolated gap. This clear functional demarcation makes it an essential part of a comprehensive electrical safety protocol, often used in conjunction with other protective devices like fuses or circuit breakers.

The JCH3-125 Circuit Breaker Switch is a versatile and safety-oriented isolation device. Its combination of a high current rating, multiple pole options, clear contact indication, and locking capability makes it a dependable choice for ensuring operational safety in electrical installations. The Circuit Breaker Switch thus represents a fundamental component for system control and personnel protection within its defined application scope.
