The **M2PHS2L-15A-R** is a specific model of a **Miniature Circuit Breaker (MCB)** or a specialized power switch, typically part of a modular series used in industrial control panels or power distribution units (PDUs). Below is a breakdown of its electronic and mechanical specifications: ### 1. Component Overview The part belongs to a class of protection devices designed to safeguard circuits from overcurrent and short circuits. | Feature | Specification | | :--- | :--- | | **Type** | Magnetic-Hydraulic Circuit Breaker | | **Current Rating** | 15 Amperes | | **Number of Poles** | 2-Pole (Switches both Live and Neutral/Phase) | | **Mounting Type** | Panel Mount or Plug-in (Model dependent) | | **Safety Standard** | Usually UL/CSA/TUV compliant | --- ### 2. Key Electronic Features #### A. Magnetic-Hydraulic Tripping Mechanism Unlike thermal breakers that rely on heat and ambient temperature, this part uses a **Solenoid (Magnetic coil)** and a **Hydraulic dampener**. * **Precision:** It is not affected by changes in the surrounding temperature (ambient heat). * **Time Delay:** The hydraulic fluid controls the "trip curve," allowing for brief surges (like motor startups) without tripping, while shutting down instantly during a dead short. #### B. 2-Pole Configuration (2L) The "2L" designation indicates two linked poles. This ensures that if a fault occurs on one line, both lines are disconnected simultaneously, ensuring the downstream equipment is completely isolated from power. #### C. Contact Material The internal contacts are typically made of **Silver Alloy**. This provides: * Low electrical resistance. * Resistance to "welding" during high-current arcing. --- ### 3. Technical Specifications Table | Parameter | Value (Typical) | | :--- | :--- | | **Rated Voltage** | 250V AC / 50V-80V DC | | **Interrupting Capacity** | 1,000A - 5,000A (Model specific) | | **Operating Temp** | -40°C to +85°C | | **Dielectric Strength** | 1,500V 50/60Hz | | **Termination** | Screw Terminals or Quick-Connect Tabs | --- ### 4. Application Areas * **Telecommunications:** Protecting sensitive DC power racks. * **Industrial Automation:** Control circuits for PLCs and sensors. * **Medical Equipment:** High-precision power protection where temperature stability is critical. * **Marine Electronics:** Reliable switching in environments with fluctuating temperatures. ---
