Motor Protection Circuit Breakers (MPCB)
Motor Protection Circuit Breakers provide motor-circuit protection through a selected breaker and coordinated switching arrangement.

Motor protection circuit breakers: supply and price enquiries
Tirupati Power Enterprises supplies motor protection circuit breakers (MPCBs) for motor feeder and starter requirements. Send the existing breaker reference or the motor nameplate, supply voltage and protection requirement for a quotation. An enquiry for “MPCB price” becomes useful when it identifies the adjustable current range and the exact series, rather than a motor kW figure alone.
Use this page for the individual motor breaker and its accessories. Contactors, complete starters and MCCBs have separate buying pages because their functions and selection information differ. For a replacement during a plant shutdown, include the required date, delivery PIN code and whether the existing contactor and mounting arrangement must be retained.
Information to include in your RFQ
Selection requirements for this product type |
|---|
Motor nameplate current and supply |
Adjustable overload range and short-circuit duty |
Coordination with contactor and accessories |
Mounting, terminals and reset/operation |
Replacement and quotation checks
For a replacement, send the existing motor protection circuit breakers (MPCB) reference and photographs of its markings, connections and mounting. Include the equipment drawing or datasheet where available. Identify which functions must remain unchanged and whether an alternative make is acceptable.

MPCB specification and accessory checklist
A thermal-magnetic motor breaker has overload and short-circuit protection characteristics that must suit the circuit. Use the exact manufacturer reference and coordination tables for the final selection.
Selection point | Specify in your enquiry | Check before ordering |
|---|---|---|
Motor and supply | Nameplate full-load current, voltage, phases and starting duty | Check the usable adjustment range and motor application |
Protection type | Required thermal-magnetic or other specified characteristic | Do not substitute a magnetic-only device for an overload function |
Fault duty | Prospective short-circuit current and operating voltage | Check the applicable breaking rating and upstream requirements |
Starter coordination | Contactor, accessories and required coordination type | Use the manufacturer-tested combination and stated conditions |
Operation and auxiliaries | Push-button/rotary operation, auxiliary/trip contacts, releases | Quote the accessory references rather than assuming they are built in |
Installation | Rail/plate mounting, terminals, enclosure/door handle | Verify dimensions, clearances and mechanical compatibility |
Price comparison: ask for the complete configuration
MPCB prices vary with series, current-setting range, breaking performance, terminal type and accessory scope. A door-mounted handle, auxiliary contact or undervoltage release may be a separate item. Compare matched model codes and the same accessories. If you need a complete motor feeder, request separate lines for breaker, contactor and enclosure so a low bare-device price does not conceal missing scope.
Send a purchase-ready enquiry
For an existing installation, send the breaker label, contactor code and a photograph showing how the assembly is mounted. Note whether trip indication or remote release contacts are connected.
For a new circuit, ask your designer to provide the fault-level and coordination requirement. A supplier quotation is most useful when those design inputs are included with the motor schedule.
- Motor nameplate photograph and supply voltage.
- Existing or requested MPCB reference and setting range.
- Fault duty, contactor reference and coordination requirement.
- Handle, releases, contacts, enclosure, quantity and delivery PIN code.
Checks before you approve the order
Distinguish adjustable range from frame size
The GV2ME14 manufacturer example is a 6–10 A thermal-magnetic reference. Treat that as one model’s specification, not a rating for every MPCB.
Retain the tested combination
Substituting one component can change the coordination evidence. Ask for the proposed breaker and contactor combination to be identified.
Match the control arrangement
Remote indication, release voltage and door operation can affect both accessory selection and enclosure fit.

Questions about Motor Protection Circuit Breakers (MPCB)
What should I check before selecting motor protection circuit breakers (MPCB)?
A motor kW label does not replace nameplate-current and fault-level checks. Confirm the exact tested manufacturer combination.
What information is needed to quote motor protection circuit breakers (MPCB)?
Provide motor nameplate current and supply; adjustable overload range and short-circuit duty; coordination with contactor and accessories; mounting, terminals and reset/operation. Include the quantity, requested make or existing reference and delivery PIN code.
What information determines an MPCB price?
The make and full reference, current-setting range, breaking duty, terminal arrangement and accessories determine the offer. Send quantities and the delivery location for a comparable quotation.
Is an MPCB the same as an MCCB?
They are different product families. An MPCB is selected for the motor circuit and its protection characteristics; an MCCB has its own trip and circuit application requirements. Do not interchange them on current rating alone.
Can I choose the current range using motor kW alone?
Use the motor nameplate current at the actual supply voltage and the application requirements. The motor kW label alone does not establish the required setting or coordination.
Does every motor breaker include overload protection?
Check the device type. Thermal-magnetic and magnetic-only references are different; the specified motor protection functions must be confirmed for the proposed model.
Can I order an MPCB with a contactor as one requirement?
Yes. Send both references or the motor and circuit schedule, plus required coordination and accessories, so the offer can identify the complete component scope.
Relevant products and guidance
DOL starter selection needs the motor nameplate current and voltage, starting duty, control supply and coordinated protection.
