6About the 40 - 63 AMP Isolator 10kA Breaking Capacity
40 - 63 AMP Isolator 10kA Breaking Capacity is a miniature circuit breaker from the VIYONA Series range, manufactured at our Mumbai works. A miniature circuit breaker protects a circuit against overload and short circuit, and resets by hand once the fault is cleared — there is no fuse wire to replace.
As listed, it has a breaking capacity of 10 kA and it is rated 40 & 63 A.
In the printed catalogue it is listed under "ISOLATOR 10 KA RANGE DOUBLE, THREE & FOUR POLE", with box quantities of 3, 4 and 6 depending on the code. It is sold by the full box, not as single pieces.
Match the rating to the load
The current rating is the maximum the accessory is built to carry, not a recommendation. A geyser, an air conditioner or an oven belongs on a 16 A or 20 A circuit of its own; lights and phone chargers do not need one. If you are unsure what a circuit draws, ask the electrician doing the installation.
Breaking capacity is not the same as the rating
The amp rating is the current the breaker carries every day. The breaking capacity is the fault current it can interrupt safely when something goes badly wrong. Both have to suit the installation, and the second is the one that makes the difference in a short circuit.

Choosing an MCB for a home board
What an MCB does
A miniature circuit breaker switches a circuit off by itself when too much current flows, whether from an overload or a short circuit. Unlike an old rewirable fuse, you reset it with a lever once the fault is cleared. The VIYONA MCBs line covers 10kA breaking-capacity MCBs, a 40–63A isolator and a 32A DP switch, so one family can fill a home or shop board.
See the full line on the VIYONA MCB page or read about our TinyTrip MCB range.
Sizing is the electrician’s job
The right rating depends on the wire in the wall, the loads on that circuit and the supply. We deliberately do not give sizing rules here.
Never swap in a higher-rated MCB because one keeps tripping. A tripping breaker is reporting a fault or an overload; a bigger breaker can let the wire overheat instead. Have a licensed electrician find the cause and size the protection.
Our article on choosing the right MCB goes deeper, still without shortcuts that replace an electrician.

Frequently asked questions
View allWhat is the current rating of the 40 - 63 AMP Isolator 10kA Breaking Capacity?
It is rated 40 & 63 A. That is the maximum the accessory is built to carry, not a target — a geyser, air conditioner or oven belongs on a higher-rated circuit of its own, while lights and chargers do not need one.
What is the breaking capacity of the 40 - 63 AMP Isolator 10kA Breaking Capacity?
10 kA. Breaking capacity is the fault current the breaker can interrupt safely in a short circuit, which is a different number from the amp rating it carries day to day. Both have to suit the installation.
How is the 40 - 63 AMP Isolator 10kA Breaking Capacity different from the 10kA Breaking Capacity MCB?
Poles: 2, 3 and 4 here, 1, 2, 3 and 4 on the 10kA Breaking Capacity MCB; Ratings: 40 A and 63 A here, 6 to 32 A, 40 A, 63 A on the 10kA Breaking Capacity MCB; MRP: ₹230 – ₹530 here, ₹145 – ₹1,035 on the 10kA Breaking Capacity MCB. Both are in our printed catalogue, which is where these figures come from.
How many 40 - 63 AMP Isolator 10kA Breaking Capacity come in a box?
The printed catalogue packs it by code: 6 to a box (442, 443); 4 to a box (452, 453); 3 to a box (461, 462). We sell by the full box, never single pieces — anyone can buy, from a homeowner to a contractor.
What do I buy with the 40 - 63 AMP Isolator 10kA Breaking Capacity?
From the same catalogue: 381 MCB distribution box, 4 way double door, ₹750; 411 VIYONA double pole MCB, 6 to 32 A, ₹350. MRPs include all taxes.
Where can I buy the 40 - 63 AMP Isolator 10kA Breaking Capacity?
Through our dealer and distributor network — we manufacture and supply the trade rather than selling direct, and orders are by the full box. Send an enquiry with your city and we will point you at the nearest stockist, or apply to become a dealer yourself.
