Product Details
1
Overview
The HITACHI LYA250A is a Molded Case Circuit Breaker (MCCB), a fundamental device for electrical protection in low-voltage power distribution systems. As part of Hitachi's "L" series, it shares core characteristics with the LPA250A but might offer distinctions in terms of specific breaking capacities, features, or intended applications within the series.

Advantages:
Overloads: When too much current flows through a circuit for an extended period, which can cause wires to overheat and damage equipment or lead to fires.
Short Circuits: When an unintended, low-resistance path is created for current to flow, resulting in an immediate and very high surge of current that can cause severe damage.

Functions:
Key Characteristics: The "250A" in LYA250A typically refers to its frame size, meaning it's built to house a trip unit with a maximum continuous current rating of up to 250 Amperes. Within this frame, various specific ampere ratings (e.g., 125A, 200A, 250A) are available.
Robust Design: Molded case circuit breakers are designed for reliable operation in demanding environments.

FAQ OF HITACHI LYA250A
| 1.Can I use the LYA250A for DC circuits? |
| MCCBs are primarily designed for AC circuits. While some MCCBs have specific DC ratings, you must check the datasheet for the exact LYA250A model to see if it has a rated DC voltage and breaking capacity. |
| 2. What does "250A" in LYA250A signify? |
The "250A" typically refers to the frame size of the circuit breaker. This indicates the maximum continuous current rating that the physical housing and internal components are designed to handle. |
| 3. Can the LYA250A be reset after it trips? |
Yes, after the fault condition (overload or short circuit) has been cleared, the LYA250A can typically be reset manually by moving its handle fully to the OFF position (if it's not already there) and then to the ON position. |
