Schneider AEG MM-PMA1-200
1. Overview
Schneider AEG MM-PMA1-200 belongs to the Modular Circuit Breaker series under Schneider Electric. Designed specifically for residential and commercial power distribution systems, this product series delivers reliable overload and short-circuit protection for electrical circuits.
2. Core Specifications
The main technical parameters of the MM-PMA1-200 series are as follows:Rated Current: 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100APoles: 1-pole, 2-pole, 3-poleRated Breaking Capacity (Icu): 8kARated Service Breaking Capacity (Icn): 10kAShort-circuit Withstand Capacity: 25kA (Typical)Maximum Operating Temperature: 40°C or 45°C (Typical)Rated Breaking Voltage (Ue): 400VRated Working Voltage (Ue): 250V
3. Product Features
- Modular Design: Adopts standard modular dimensions for easy installation, and can be directly plugged into Schneider Electric standard distribution boxes (e.g., PrismaLine series).
- High Safety Performance: With 8kA rated breaking capacity and 10kA rated service breaking capacity, it can quickly cut off the circuit in case of electrical system faults, protecting wires and equipment from damage.
- Temperature Characteristics: Optional B/C/D curve characteristics are available based on installation environments, suitable for different types of electrical loads.
- User-friendly Mechanical Structure: Humanized switch handle design with moderate operating torque for convenient manual operation.
4. Structure & Components
The MM-PMA1-200 modular circuit breaker consists of the following key components:
- Body: Including shell and internal mechanical structure
- Tripping Mechanism: Triggers circuit breaking in case of overload or short circuit
- Spring Set: Determines the current characteristics (B/C/D curve) for overload protection
- Contact Set: Controls current conduction and interruption
- Terminals: For wire connection
- Handle: For manual on/off operation
5. Application Scenarios
The MM-PMA1-200 series is mainly applied in the following scenarios:
- Residential Power Distribution: Branch circuit protection for home living areas, kitchens, bathrooms, etc.
- Commercial Buildings: Protection for lighting and socket circuits in office buildings and stores.
- Industrial Power Distribution: Suitable for industrial branch circuits with low requirements for overload current.
6. Installation & Maintenance
Installation
It must be installed in Schneider Electric standard modular distribution boxes (e.g., PrismaLine series). Before installation, confirm that the rated voltage and current of the distribution box meet the circuit requirements.
Maintenance
It is recommended to regularly inspect the appearance of the circuit breaker to ensure no obvious deformation or damage. For circuit breakers that trip frequently, check whether the load exceeds the rated value or if there is a circuit fault. Do not disassemble and repair the circuit breaker by yourself; contact professional electricians or authorized service centers for repair or replacement.
7. Selection Recommendations
- Current Selection: Select the model according to the rated current of the circuit (usually 1.25 times the load current).
- Short-circuit Capacity: Ensure the rated short-circuit capacity of the installed distribution box is not lower than 10kA (the rated short-circuit capacity of the circuit breaker).
- Ambient Temperature: Select the corresponding temperature characteristic model based on the ambient temperature of the distribution box installation site.
