Description:
The MT-3RV1Â Motor Protection Combo integrates a high-performance molded case circuit breaker (MCCB) with the 3RV1Â series motor protector, forming a comprehensive protection solution for low-voltage motor circuits. This combination safeguards motors against short circuits, overloads, and phase loss while ensuring smooth operation in industrial environments.
Constructed from durable thermosetting materials and designed for compact installation, this system is ideal for motor control centers, machinery panels, and industrial automation setups. It offers precise protection for motors ranging from 0.1A to 32A, with easy installation and intuitive operation for maintenance personnel.
Applications:
The MT-3RV1Â combo is widely deployed across industrial and commercial sectors to ensure continuous, reliable motor operation. Typical use cases include:
Pumps, compressors, and fans
Conveyors and material handling equipment
Machine tools and processing lines
Agricultural and food processing machinery
Renewable energy motor-driven systems
Motor circuit breaker has overload and short circuit protection function. Overload is achieved by heating and bending the bimetallic strip, tripping the top trip mechanism, and realizing line protection. Compared with thermal magnetic molded case circuit breakers, it has higher accuracy, smaller current, and more accurate protection. Practical motor protection. Short circuit protection is achieved by generating a Lorentz magnetic force through a coil, and the iron core is driven by the magnetic force to trigger a tripping mechanism, which opens the circuit breaker, disconnects the circuit, and protects the motor. It is generally used for high current protection during motor start-up.
| 1.We have button styles as well as knob styles | |
