Product Overview
The CDM1-125L/32202 125A molded case circuit breaker employs thermomagnetic trip technology for low-voltage distribution protection, suitable for 50/60Hz AC systems up to 400V. Its modular design features compact dimensions and flexible operation, providing reliable overload and short-circuit protection for circuits. The 125A rated current meets mainstream commercial/industrial demands, with a gray-white color scheme aligning with contemporary electrical aesthetics.17
Key Features
Dual protection is achieved through thermal response for overloads and magnetic instant trip for short circuits. Multiple installation options include fixed, plug-in, front/rear-mounted versions for adaptable panel integration. The visible-trip handle indicates clear ON/OFF positions, with optional extended handles for remote operation. Isolated contact design ensures maintenance safety with visible gap in OFF state.1316
Specifications
In model code "3220", "3" denotes 3-pole configuration while "220" indicates electromagnetic trip unit. With 25kA breaking capacity, it withstands fault currents effectively. Silver-alloy contacts and arc chutes ensure 10,000+ electrical cycles. Operating range covers -5°C to +40°C at ≤95% humidity (IP20 rated). Motor protection variants feature specialized trip curves to avoid nuisance tripping during startup.717
Applications
Ideal for building distribution, industrial control panels and power substations, particularly in motor circuits and branch protection. Compact DIN-rail compatible size (96×96mm) suits PV combiner boxes and pump control cabinets. Supports accessories like shunt trips and undervoltage releases for automation integration.1218
