The Schneider EZD 4P 100E is a 4-pole molded case circuit breaker (MCCB) designed for overload and short-circuit protection in four-wire electrical systems, commonly used in industrial, commercial, and residential applications.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 4P (4 poles) – Suitable for four-wire systems (3-phase + neutral)
Current Rating: 100A
Frame Size: EZD (denotes the frame size and protection settings for moderate current systems)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal-Magnetic Protection: Provides thermal protection for overload conditions and magnetic protection for short-circuit conditions.
Fixed Thermal and Magnetic Protection Settings: The E characteristic denotes fixed protection settings, making this breaker ideal for applications where the protection level does not require customization.
Magnetic Trip: Provides instantaneous disconnection when a short circuit is detected, protecting sensitive components and electrical wiring.
Breaking Capacity: Typically 25 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: The breaker will disconnect the circuit when current exceeds the rated value for a prolonged period, protecting the system from overheating.
Short-Circuit Protection: The breaker will trip instantly in the event of a short circuit, minimizing damage to equipment and the electrical system.
Manual Reset: After tripping, the breaker can be manually reset once the fault is cleared, allowing the system to resume normal operation.
