What is a Thermal Magnetic MCCB?

A Thermal Magnetic MCCB is a molded case circuit breaker that combines two trip mechanisms in one compact device. The thermal part uses a bimetallic strip to provide inverse-time overload protection, while the magnetic part uses an electromagnetic solenoid for instantaneous short-circuit protection. Together, they help prevent cable overheating, equipment damage, and serious faults in low-voltage power distribution systems.

How to Select the Right Thermal Magnetic MCCB?

Choosing the right Thermal Magnetic MCCB starts with matching the rated current to your load. From small distribution panels to high-capacity feeders up to 2000 A, the breaker has to match real operating conditions. Always confirm the breaking capacity so it can safely clear the maximum fault current at the installation point.

As a professional MCCB manufacturer and factory, KRIPAL offers 3-pole and 4-pole breakers in multiple frame sizes and current ranges. We supply different trip units to fit various system designs, ambient temperatures, and installation environments. Our factory engineering team can support coordination with upstream and downstream devices and help you select the right accessories.

Frequently Asked Questions

How a Thermal Magnetic MCCB Works?

A Thermal Magnetic MCCB is a molded case circuit breaker that uses two trip technologies in one device: thermal and magnetic. The thermal trip uses a bimetal strip that bends as it heats up. It provides inverse-time overload protection, so the higher the overload, the faster it trips and protects cables and equipment. The magnetic trip uses an electromagnetic coil that reacts instantly to very high fault current. It trips the breaker in milliseconds to clear short circuits and prevent serious damage to the installation.

What is the difference between a Thermal Magnetic MCCB and an Electronic Trip MCCB?

A Thermal Magnetic MCCB uses a bimetal strip and magnetic coil. It is a proven, cost-effective solution with fixed or limited-adjustable trip characteristics and no need for an external power supply. An Electronic Trip MCCB uses current sensors and a microprocessor. It offers adjustable protection settings, more precise coordination, metering, and communication options, making it ideal for advanced power management and energy monitoring. KRIPAL Thermal Magnetic MCCBs are a solid choice where you need high reliability and simple setup without complex programming.

Are KRIPAL MCCBs compliant with international standards?

Yes. KRIPAL Thermal Magnetic MCCBs are designed and tested in line with IEC 60947-2, the main international standard for low-voltage circuit breakers. Compliance with IEC standards helps ensure consistent breaking performance, insulation levels, temperature rise limits, and safety clearances so you can use KRIPAL products in global projects with confidence.

What is the maximum current rating for Thermal Magnetic MCCBs?

KRIPAL MCCBs are available from lower currents for sub-distribution right up to high-capacity models for main feeders. Typical ranges go up to 2000 A, which covers most industrial plants, commercial complexes, and infrastructure installations. This allows one manufacturer and one product platform to be used from small panels to large main distribution boards in the same project.

Can MCCBs be equipped with auxiliary accessories?

Yes. KRIPAL MCCBs can be fitted with a range of accessories to meet control and monitoring needs in modern panels. Common options include auxiliary contacts for status indication, shunt trips for remote opening, and under-voltage releases that trip the breaker when supply voltage drops below a safe level. Handles, rotary operating mechanisms, and extension shafts are available for different door depths and panel layouts, making installation more flexible for panel builders.
