Is this the right one for you?

Check these three things before you order:

• The circuit is DC - a battery bank, inverter or other DC supply. AC MCBs are not meant for DC circuits.
• The DC circuit is within 250 V DC and only one conductor needs switching - for example where the other is earthed. Solar strings and floating (unearthed) DC systems normally need both conductors switched - use the DP or FP.
• The rating you need is 0.5, 1, 2, 3, 4, 5, 6, 10, 16, 20, 25, 32, 40, 50 or 63 A.

Why choose the Polycab DC MCB SP

• 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
• Rated 250 V DC per pole with a 6 kA breaking capacity, made to IEC 60947-2 (Polycab catalogue)
• Polycab item code and MRP for every rating, so the order matches the drawing - GMM401P001 to GMM401P008 and GMM401P012 to GMM401P018

How to choose and fit it

Why a DC breaker. A DC arc does not pass through zero like an AC arc, so it is harder to break, and DC circuits need a DC-rated MCB, not an AC MCB. This SP version suits circuits where one conductor is earthed; for solar strings and floating DC systems use the DP or FP.

Voltage and poles. Polycab rates its DC MCBs at 250 V DC per pole. For higher DC voltages the poles are connected in series according to the manufacturer's wiring instructions - send us the system voltage and current and we will confirm which version fits.

This version. The SP version has one pole, which switches one conductor of a DC circuit within 250 V DC. Polycab lists the DC MCB in SP, DP and FP.

Rating. Choose a rating above the normal DC current of the circuit (for a battery circuit, its maximum charge or discharge current) and within the current-carrying capacity of the DC cable.

Mounting. It clips on a standard DIN rail in a DC combiner box or enclosure.

Where it is used

• DC circuits within 250 V DC where only one conductor is switched - for example where the other conductor is earthed
• battery, inverter and UPS DC circuits within 250 V DC
• DC control and auxiliary circuits

Frequently asked questions

Can I use an ordinary AC MCB in a solar or battery circuit?

No. A DC arc is harder to break than an AC arc, so DC circuits need a DC-rated breaker such as the Polycab DC MCB, made to IEC 60947-2.

What voltage is the Polycab DC MCB rated for?

250 V DC per pole, as Polycab's catalogue states. For higher DC voltages the poles are wired in series according to the manufacturer's wiring instructions - send us the system voltage and we will confirm the right version.

Which pole count do I need?

SP where only one conductor of a DC circuit within 250 V DC needs switching, for example where the other is earthed; DP to switch both conductors - the usual choice for solar strings and floating (unearthed) DC systems; FP where the system voltage needs poles in series, for example two in each conductor. Each pole is rated 250 V DC, so tell us the system voltage, current and earthing and we will confirm the version.

Which ratings are available?

0.5, 1, 2, 3, 4, 5, 6, 10, 16, 20, 25, 32, 40, 50 and 63 A, all C curve and 6 kA, in SP, DP and FP versions.
