Is this the right one for you?

Check these five things before you order:

• The load is three-phase without neutral, for example a three-phase motor (triple pole).
• Your load suits a C curve: three-phase pumps, compressors, motors and mixed three-phase loads.
• The prospective short-circuit current where the MCB is fitted does not exceed 6 kA.
• The rating you need is 6, 10, 16, 20, 25 or 32 A - the rating must suit the cable it protects.
• The installation does not call for a 10 kA breaker - for higher fault levels use the 10 kA range.

Why choose the Polycab 6kA C-Curve TP MCB

• Finger-proof IP20 terminals
• Air-flow channels to keep the breaker cool
• 13-plate arc chute for quick arc quenching
• Line-load reversibility - it can be fed from the top or the bottom
• Energy limiting class 3 and low power loss, as Polycab's catalogue lists for the 6 kA range
• Polycab item code and MRP for every rating, so the order matches the drawing - GMM603P001 to GMM603P006

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 three-phase loads with a moderate switch-on surge - pumps, compressors, air-handling units, motors and the mixed loads of three-phase sub-boards; it is the most widely used curve.

Poles. A triple pole MCB is used for a three-phase load without neutral, such as a three-phase motor or pump. In the 6 kA C-curve range Polycab lists SP, SPN, DP, TP and FP.

Breaking capacity. 6 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. Choose a rating above the running current of the load and within the current-carrying capacity of the cable it protects; for motors, also check the starting current against the curve and the motor maker's recommendation.

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

Where it is used

• three-phase pumps, compressors, air-handling units and machines without neutral
• three-phase sub-mains without neutral
• homes, flats and small shops

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 three-phase pumps, compressors, motors and mixed three-phase loads. 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 triple pole (TP) version; in the 6 kA C-curve range Polycab lists SP, SPN, DP, TP 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 TP 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.
