The safest way to switch on.
The Norwood MCB's demonstrates proven endurance against overloads and short circuits
with its high current carrying capacity engineered to support easy installation. Each MCB is designed
keeping in mind the highest safety and compliance parameters. This means zero exposure to live parts,
and a user-friendly, efficient interface that makes Norwood the only safe and reliable choice.
Endurance
The products have high electrical and mechanical endurance, with ambient temperatures of -25° C to + 70° C
Breaking capacity
Norwood MCBs have a breaking capacity of 10kA.
Line load reversibility
The design enables line load reversibility in MCB's which means that you can connect the load from
either side (top or bottom) of the MCB.
Application
It can be installed where there is a fire safety requirement. Norwood MCB can be installed in a
residential apartments, offices, industrial units, high rise buildings, schools, theatres etc.
The Quintessential Life Saving Equipment For Your Home.
A Residual Current Circuit Breaker (RCCB) is an important safety measure when it comes to protection of electrical circuits. It is a current sensing device, which can automatically measure and disconnect the circuit whenever a fault occurs in the connected circuit or the current exceeds the rated sensitivity.
Norwood RCCB works on the principle of Kirchhoff’s law, which states that the incoming current must be equal to the outgoing current in a circuit. Norwood RCCB thus compares the difference in current values between live and neutral wires. Ideally, the current flowing to the circuit from the live wire should be the same as that flowing through the neutral wire. In case of a fault, the current from the neutral wire is reduced and the differential between the two is known as Residual Current. On spotting a Residual Current, the RCCB is triggered to trip off the circuit.
Features Of Norwood RCCB
- Provides protection against earth fault as well as any leakage current.
- Automatically disconnects the circuit when the rated sensitivity is exceeded.
- Offers possibility of dual termination both for cable and busbar connections.
- Offers protection against voltage fluctuation as it includes a filtering device that guards against transient voltage levels.
Specifications

Specifications
Conforms to IS / IFC: 60947 ( Pt)- 1 & 3.
Insulation
Specially formulated grade of Flame Retardant (FR) compound is used. The performance of the
cable in a fire situation is exceptionally good. The insulation does not burn readily. It does not
melt and drip. The smoke is negligible, transparent, non toxic. The victims trapped in fire do
not suffocate and this facilitates fire fighting operations. Unlike general purpose PVC, the
smoke emitted is non-corrosive. Thus, the electronic printed circuit boards, hard disks
and other sensitive electronic equipments are unaffected.
Salient features
- Complete interchangeability between vitreous steatite porcelain Rewireable carries and HRC fuse carries.
- HRC type porcelain fuse carriers are available for current rating 16A,32A, 63A,and 100A
- Quick make and break operating mechanism, independent of the speed of the operator, minimizes the arc.
- Available in SPN, DP, and TPN version.
- Adequate sized silver plated terminals, suitable for copper/ aluminum cable/bus-bar termination are provided with terminal cover shields to prevent any accidental contact with live contacts.
- The switches are provide with door interlock to ensure that the switch cannot be opened in 'ON' condition.
- The enclosures are surface-mounted, made of thick gauge CRCA sheets, protected with phosphate coating by an eight tank system and are fitted to removable top & bottom end plates with adequately sized double knockouts cable entry & exit.
- Electrical contracts are made of electrolytic grade copper, silver plated for better conductivity and greater resistance to corrosion.
- Specially designed female contacts ensure low contact resistance and better arc-control.
- Buffer stoppers to prevent carrier ejection under faulty condition
- Successfully tested at Central Power Research Institute (CPRI) and Electrical Research Development Association (ERDA)
Make your life safer.
A Norwood fuse is an electrical safety device that operates to provide over current protection of an electrical circuit. Its essential component is a metal wire or strip that melts when excess current flows through it, thereby stopping or interrupting the current. It is a sacrificial device once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type.
The time and current operating characteristics of Norwood fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. Short circuits, overloading, mismatched loads, or device failure are the prime or some of the reasons for fuse operation.
A Norwood fuse unit is an automatic means of removing power from a faulty system.
Be efficient. Stay safe.
Norwood Distribution boards make an essential part of any circuit in your homes, offices or any other place. They serve an important purpose and cannot be ignored at any cost. One of the most important devices, they make sure that the current is properly distributed to all the devices allowing proper functioning. This also makes sure that none of the devices suffer from the effects of over currents or short circuits.
The Norwood range of distribution boards are elegant when it comes to their looks. They fit in perfectly with the interiors of your homes, adding to the aesthetics. Available in different colors, the designer DBs serve a dual purpose. They not only save you from the harmful effects of current but also make your walls magnificent. The horizontal and vertical DBs give you the flexibility to choose the ones that are right for you.
