The Schneider EZD250E/200 is a 3-pole molded case circuit breaker (MCCB) designed to provide overload and short-circuit protection in industrial, commercial, and residential electrical systems.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 250A
Frame Size: 200 (indicating the frame size, typically rated to handle circuits up to 250A)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal-Magnetic Protection: Provides both thermal protection for overload conditions and magnetic protection for short-circuit protection.
Adjustable Thermal and Magnetic Settings: The thermal and magnetic protection settings can be adjusted to tailor the breaker’s performance for different applications, offering flexible protection.
Magnetic Trip: The breaker disconnects instantly in the event of a short circuit, ensuring the safety of the system and preventing further damage.
Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Disconnects the circuit when the current exceeds the rated value for a prolonged period, preventing damage to cables, wiring, and connected devices.
Short-Circuit Protection: Provides instantaneous disconnection when a short circuit is detected, preventing catastrophic failure of the electrical infrastructure.
Manual Reset: After tripping, the breaker can be manually reset once the fault is cleared, restoring power to the system.
