Is this the right one for you?

Check these four things before you order:

• You are protecting one single-phase circuit from the distribution board (single pole).
• Your load suits a C curve: general and mixed loads (ACs, pumps, motors, lighting banks).
• The prospective short-circuit current where the MCB is fitted does not exceed 10 kA.
• The rating you need is 0.5, 1, 2, 3, 4, 5, 6, 10, 16, 20, 25, 32, 40 or 63 A - the rating must suit the cable it protects.

Why choose the Polycab 10kA C-Curve SP MCB

• Easy removal from the DIN rail
• Positive contact position indication - the handle shows whether the contacts are really open
• Finger-proof IP20 terminals
• Air-flow channels to keep the breaker cool
• Label holder to mark the circuit
• 7-year warranty listed by Polycab
• High-quality contact tips
• Large terminals that take copper or aluminium conductors
• Bi-connect terminals on both sides - busbar or cable
• Line-load reversibility - it can be fed from the top or the bottom
• 10 kA breaking capacity, and energy limiting class 3 as Polycab's catalogue lists for the range
• Polycab item code and MRP for every rating, so the order matches the drawing - GMM201P001 to GMM201P008 and GMM201P012 to GMM201P017

How to choose and fit it

Tripping curve. Under IS/IEC 60898-1, a B-curve MCB trips instantly at 3 to 5 times its rated current, a C-curve at 5 to 10 times and a D-curve at 10 to 20 times. This C-curve breaker trips instantly at 5 to 10 times its rating, which suits mixed loads with a moderate switch-on surge - air conditioners, refrigerators, pumps, small motors and banks of LED or fluorescent lighting; it is the most widely used curve.

Poles. A single pole MCB is used for a single-phase final circuit - it protects the phase conductor of one circuit leaving the distribution board. In the 10 kA C-curve range Polycab lists SP, SPN, DP, TP, TPN and FP.

Breaking capacity. 10 kA is the largest short-circuit current the breaker can safely interrupt. Choose a breaking capacity at least equal to the prospective fault current where it is fitted - your electrician or consultant checks this at the board.

Rating. The MCB rating must be above the normal current of the load and must not exceed the current-carrying capacity of the cable it protects. As a rough guide in homes: 6 A or 10 A for lighting, 16 A for power sockets and 20 A or 25 A for an air conditioner or geyser circuit; the cable size and the load decide the final choice.

Mounting. It clips on a standard DIN rail inside a distribution board or MCB enclosure.

Where it is used

• final circuits in homes, flats, offices and shops - lighting, fan, socket and appliance circuits
• outgoing ways of SPN and TPN distribution boards
• air conditioners, refrigerators and other mixed loads
• homes, apartments, offices, shops, hospitals, schools and factories

Frequently asked questions

What does "C curve" mean on an MCB?

It describes how quickly the breaker trips on a surge. Under IS/IEC 60898-1 a C-curve MCB trips instantly at 5 to 10 times its rated current, which suits general and mixed loads (ACs, pumps, motors, lighting banks). B trips at 3 to 5 times, C at 5 to 10 times and D at 10 to 20 times the rating.

Which pole type do I need?

SP protects one single-phase circuit; SPN switches the neutral together with the phase; DP switches and protects phase and neutral of a single-phase supply; TP is for three-phase loads without neutral; TPN switches the neutral together with the three phases; FP switches all four poles of a three-phase supply with neutral and is the usual incomer of a TPN distribution board. This page is the single pole (SP) version; in the 10 kA C-curve range Polycab lists SP, SPN, DP, TP, TPN and FP.

Should I choose a 10 kA or a 6 kA MCB?

Choose a breaking capacity at least equal to the prospective short-circuit current at the board. 6 kA is common in homes; 10 kA is the safer choice for commercial buildings, boards close to the transformer and industrial supplies. Polycab makes the SP C-curve MCB in both.

Do I still need an RCCB with an MCB?

Yes, for protection against electric shock and earth-leakage fires. An MCB protects against overload and short circuit only; an RCCB (or an RCBO, which combines both) detects current leaking to earth.

What is the MRP of the Polycab 32 A 10kA C-curve SP MCB?

Rs 248 per piece, item code GMM201P006 - the MRP listed on polycab.com in October 2026, inclusive of taxes. Call +91 9340081159 for the selling price and stock.
