Is this the right one for you?

Check these four things before you order:

• You need to switch and isolate one conductor of a single-phase circuit (single pole).
• Overload and short-circuit protection comes from an MCB, RCBO or fuse - an isolator does not trip.
• The rating you need is 40 or 63 A, at least the current of the circuit it switches.
• You want a switch that can be padlocked off during maintenance.

How to choose and fit it

What an isolator does. It switches the load on and off and, when off, separates the circuit from the supply so that work can be done on it safely. It has no automatic trip.

Protection. Fit it with an MCB, RCBO or fuse for overload and short-circuit protection, and an RCCB where earth-leakage protection is needed.

Rating. Choose a rating at least equal to the current of the circuit, and at least the rating of the protective device ahead of it. Polycab lists 40 and 63 A.

Poles. The single pole version switches one conductor of a single-phase circuit. Polycab makes the isolator in SP, DP, TP and FP.

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

Where it is used

• switching a single-phase lighting or small-power circuit - an SP isolator does not isolate the neutral; use DP to isolate a single-phase supply
• homes, offices, shops, hospitals and factories

Frequently asked questions

What is the difference between an isolator and an MCB?

An isolator is a switch: it switches the load and isolates the circuit, but it does not trip on overload or short circuit. An MCB switches and also trips automatically on overload and short circuit.

What does AC-22A mean?

It is the utilisation category under IS/IEC 60947-3 for switching mixed resistive and inductive loads, including moderate overloads - the usual duty of a distribution-board main switch.

Which rating should I choose?

At least the current of the circuit and at least the rating of the MCB or fuse ahead of it. Polycab lists the SP isolator in 40 and 63 A.

Can it be locked off?

Yes - Polycab lists a padlocking provision, so it can be locked in the off position while someone works on the circuit.

What is the MRP of the Polycab SP isolator 63 A?

Rs 472 per piece, item code GMS501P002 - the MRP listed on polycab.com in October 2026, inclusive of taxes. Call +91 9340081159 for the selling price and stock.
