2P 30A Molded Case Circuit Breaker

In modern electrical systems, safety is the cornerstone that cannot be compromised. The SPX durable 2P 30A Molded Case Circuit Breaker is such a silent and loyal "safety guard". It simultaneously monitors the live and neutral wires (or two phase wires) of the circuit. When abnormal current occurs, it can act accurately within milliseconds and automatically cut off the faulty circuit. It integrates the protection function of traditional fuses with the convenience of switch operation, providing you with a safer, more intelligent, and reusable line protection tool.

Advantage

The high quality 2P 30A Molded Case Circuit Breaker's built-in bimetallic strip provides inverse time overload protection. When the current slightly exceeds the rated value for a long time, such as line overload, it will delay disconnection; Electromagnetic coils provide instantaneous short circuit protection, and can trip instantly within one percent of a second when encountering sudden and extremely large short circuit currents, with extremely rapid response.

The "ON" and "OFF" positions are clearly marked, and the handle operation is smooth. After the fault is tripped, the handle will be in the middle position, providing intuitive fault indication for quick troubleshooting.
Stable wiring and installation: using screw pressed wire terminals, the high current connection is firm and reliable; Standardized modular design allows for easy installation on 35mm universal rails and neat arrangement with other electrical components.
The two pole design provides complete breaking protection while being only about twice the width of a standard single pole circuit breaker. The CE-certified 2P 30A Molded Case Circuit Breaker is an option for small distribution boxes and subdivision circuit
protection.
Compared to fuses that need to be replaced, 2P 30A Molded Case Circuit Breakers can be manually reset and reused after troubleshooting, with lower long-term usage costs and easier maintenance.
