Manual Motor Starter

The KRIPAL UKS-M Series MPCB is engineered to provide comprehensive protection for three-phase squirrel-cage induction motors. It seamlessly integrates reliable overload protection and rapid short-circuit protection into a single, compact device. Featuring a user-friendly push-button operation design, it offers convenient control while safeguarding critical equipment against damage from overheating and electrical faults, ensuring operational continuity across industrial, commercial, and residential applications.

The UKS Series employs a dual-protection mechanism:

Overload Protection: It automatically monitors current and cuts off power during sustained overload conditions, preventing motor damage caused by overheating.

Short-Circuit Protection: It instantaneously responds to high fault currents, interrupting the circuit to prevent serious hazards like electrical fires and equipment destruction.

This breaker is versatile and robust, designed for a wide range of environments:

• Industrial: Reliable protection for critical machinery like factory fans, pumps, and conveyor motors.
• Commercial: Essential for enhancing the reliability of air conditioning systems and elevator controls, minimising maintenance needs.
• Residential: Provides secure safety for higher-power household appliances such as central air conditioning units and water pumps.

The push-button operation offers superior convenience and safety compared to traditional toggle switches. It allows for quick and easy manual control (ON/OFF) and provides clear operational feedback, simplifying use for personnel and contributing to safer maintenance procedures.

Selecting the correct MPCB is crucial. The key is to match the breaker's current rating with your motor's full-load amperage (FLA), which can be found on the motor's nameplate. It is recommended to consult the KRIPAL technical selection guide or contact our support team to ensure optimal protection for your specific motor type, power rating, and application requirements.

Yes. The KRIPAL UKS-M Series MPCB is designed to function as an all-in-one solution that combines the roles of a protector, a manual ON/OFF switch, and a safety isolator. This eliminates the need for a separate disconnecting switch in many applications, saving space and cost.

A standard circuit breaker is designed primarily to protect the wiring in an electrical circuit. In contrast, a dedicated MPCB like the UKS-M Series is specifically calibrated to protect the motor itself. Its thermal response characteristics are engineered to tolerate the brief, high inrush current of a motor starting while still providing sensitive protection against dangerous sustained overloads that can burn out motor windings.
