Molded Case Circuit Breaker (MCCB)

CHM6-250N Molded Case Circuit Breaker 250A Thermal Magnetic Adjustable Multi-Voltage Breaking MCCB

Core Advantages
Precise Protection: The thermal-magnetic circuit breaker supports adjustable overload and short-circuit thresholds, adapting to complex loads such as motor starting and main line power distribution, preventing false trips.
Multi-Voltage Compatibility: A single product covers 240V (residential) to 690V (industrial high voltage), reducing inventory and suitable for export/multinational projects.
Convenient Operation and Maintenance: A transparent window intuitively displays parameters, a TRIP button allows for one-click testing, and input/output terminals are clearly marked (1/3/5 for input, 2/4/6 for output).

Typical Scenarios

Industrial: Motor control (fans, pumps, adjusting Ir to match starting current);
Commercial: Power distribution in shopping malls and data centers (adapting to multi-floor voltage);
Export: Directly meets IEC standards and is compatible with overseas equipment.
