The Schneider EZD 3P 100M 30A is a 3-pole molded case circuit breaker (MCCB) from the EZD series, designed for overload and short-circuit protection in three-phase electrical systems.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 30A
Frame Size: 100M (indicating the frame size and protection for medium current applications)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: Provides overload protection by disconnecting the circuit when the current exceeds the rated value for an extended period, preventing overheating of conductors and connected equipment.
Magnetic Protection: Provides instantaneous disconnection when a short-circuit condition is detected, minimizing the damage caused by a fault and ensuring the safety of the electrical system.
Adjustable Thermal Settings: The thermal protection settings can be adjusted to suit the specific load requirements, providing flexibility for different types of loads (e.g., motors, lighting circuits).
Breaking Capacity: Typically 25 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: The breaker will trip when the current exceeds the rated value for an extended period, protecting the circuit from overheating.
Short-Circuit Protection: Provides instantaneous protection against short circuits, disconnecting the circuit immediately when a fault occurs.
Manual Reset: After tripping, the breaker can be manually reset once the fault is cleared, allowing the system to return to normal operation.
