FAQ's of LT (DH-250) 250A 3P MCCB:

Q: How can I install the LT (DH-250) 250A 3P MCCB in a panel?

A: You can install the LT (DH-250) MCCB using either flush or plug-in mounting styles directly onto your panel board. Make sure the direct terminal connection is securely fastened, and follow standard installation practices for three-phase breakers to ensure safe and reliable operation.

Q: What is the benefit of the adjustable 200-250A setting on this MCCB?

A: The adjustable range allows you to fine-tune the breaker's trip setting to match your specific circuit requirements, ensuring optimal protection for both equipment and wiring. This flexibility is particularly valuable in facilities with fluctuating load demands.

Q: When should an auxiliary contact option be considered for this MCCB?

A: Auxiliary contacts are recommended when you need status signaling or remote monitoring of breaker operation in your control system. This is useful for automated processes where feedback on the position (ON/OFF/tripped) of the MCCB enhances system safety and diagnostics.

Q: Where is this MCCB typically used?

A: The LT (DH-250) 250A 3P MCCB is ideal for heavy-duty applications in industrial, commercial, and infrastructure projects across India. It's commonly used in power distribution panels, motor control centers, and large machinery control circuits.

Q: What processes does the LT (DH-250) MCCB protect against?

A: This MCCB safeguards electrical circuits from overcurrent, short circuit, and temperature-related faults. The thermal magnetic tripping technology ensures precise interruption under abnormal conditions, protecting both installations and connected devices.

Q: How does the degree of protection (IP20) impact usage?

A: The IP20 rating ensures that the front terminals are protected against accidental finger contact, enhancing operator safety during installation and maintenance. However, the MCCB should be installed in an enclosure or location that provides further protection from dust and moisture.
