The Highlight 20A Circuit Breaker is a single pole miniature circuit breaker (MCB) rated for 240V/415V systems, IEC 60898-1 certified with 6000A breaking capacity. It’s built for electricians, contractors, and homeowners protecting socket circuits and moderate-load appliances that exceed 16A but don’t need a double pole 32A breaker. DIN rail mounted for standard distribution boards across Pakistan.
Key Features of 20A Circuit Breaker
- 20A rated current, single pole (1P) switching
- 240V/415V compatible — fits standard Pakistani distribution boards
- IEC 60898-1 certified, 6000A breaking capacity
- Compact single-module DIN rail mount
- Quick manual ON/OFF toggle with clear position indicator
- Highlight brand — consistent quality across the 10A/16A/20A/32A range
Product Overview
The 20A Circuit Breaker sits between the 16A and 32A breakers in the Highlight range, built for circuits carrying a moderate load that a 16A breaker would trip under. It’s a single pole MCB, meaning it switches the live wire only — the standard choice for lighting circuits, socket outlets, and small to mid-sized appliance loads.
Built to IEC 60898-1 standards, this breaker trips reliably during overloads and short circuits while resisting nuisance tripping under normal daily switching. The single-module DIN rail design fits standard distribution boards without modification, making it a straightforward swap or new install for electricians and homeowners alike.
Why Choose This Product
Picking the wrong amp rating is a common wiring mistake. A 16A breaker on a socket circuit carrying slightly heavier loads trips repeatedly under normal use — annoying, and it often leads people to “fix” it by installing an oversized breaker that no longer protects the wiring correctly. The 20A rating closes that gap: enough headroom for socket circuits and moderate appliance loads, without over-sizing into 32A double pole territory meant for ACs and pumps.
Because it’s part of the same certified Highlight range as the 10A, 16A, and 32A breakers already sold on Smart Living Pakistan, it uses the same DIN rail footprint and installation process — no surprises for anyone already familiar with the brand.
Best For
- Socket outlet circuits carrying moderate load
- Kitchen and utility circuits with small appliances
- Home office and workstation power circuits
- Replacing a nuisance-tripping 16A breaker on a heavier circuit
- Apartments, offices, and small commercial spaces
- New distribution board installations

Compatibility
This breaker fits standard single-module DIN rail distribution boards used across Pakistani residential and light commercial installations. It’s compatible with 240V single-phase and 415V three-phase systems. Suitable for electricians upgrading an existing board, contractors wiring new installations, and homeowners replacing an undersized breaker — installation should be carried out by a qualified electrician.
Applications
Used in home distribution boards to protect socket and lighting circuits carrying a moderate load. Common in kitchens where multiple small appliances share a circuit, home offices with computer and peripheral loads, and small shops or offices distributing power across several outlets. Also used as a direct replacement when an existing 16A breaker trips too often under normal daily use, without jumping straight to a 32A double pole breaker that’s oversized for the actual load.
Buying Guide
Choosing the right amp rating comes down to matching the breaker to the actual circuit load — not going bigger “to be safe.”
- 10A — lighting points, ceiling fans, light circuits only
- 16A — standard socket outlets, general room circuits
- 20A — socket circuits with moderate combined load, kitchens, home office setups
- 32A (Double Pole) — air conditioners, motor pumps, main distribution feeds
Common mistake: Installing a 32A breaker on a 20A-load circuit “for safety” — this doesn’t protect the wiring correctly, since the breaker won’t trip fast enough on a fault sized for the actual (smaller) wire gauge. Always match the breaker to the circuit’s wire gauge and expected load, not just the appliance’s peak draw.
Single Pole vs Double Pole: Single pole switches only the live wire — standard for most branch circuits. Double pole switches both live and neutral together — required for higher-load circuits like ACs and pumps. This 20A breaker is single pole, suited for socket and lighting circuits rather than heavy appliance feeds.
Installation
- Switch OFF the main power supply before opening the distribution board
- Clip the breaker onto the DIN rail in the correct slot
- Connect the incoming and outgoing circuit wires to the correct terminals
- Tighten all terminal screws securely
- Restore power and test the ON/OFF toggle for clean operation
Professional installation by a certified electrician is recommended.

Frequently Asked Questions
What is a 20A circuit breaker used for?
It protects electrical circuits carrying up to 20 Amps — typically socket outlets, kitchen circuits, and moderate-load home office setups — from overloads and short circuits.
Is this a single pole or double pole breaker?
This is a Single Pole (1P) MCB, switching the live wire. For higher-load circuits like ACs or pumps, a double pole breaker (like our 32A) is the correct choice.
Can this MCB 20A single pole breaker be installed in a home distribution board?
Yes — it’s a standard single-module DIN rail breaker that fits any standard residential or light commercial distribution board.
What voltage does it support?
It’s rated for 240V/415V AC electrical systems, standard across Pakistan.
How is 20A different from 16A?
20A gives more headroom before tripping, suited for circuits with a slightly heavier combined load than a standard 16A socket circuit is built for — without jumping to a 32A double pole breaker.
Does it protect against short circuits?
Yes — it provides both overload and short-circuit protection, certified to IEC 60898-1.
Can I install this myself?
Basic DIN rail mounting is straightforward, but connecting to live distribution board wiring should always be done by a certified electrician for safety.
Is this suitable for commercial use?
Yes — it’s suitable for residential and light commercial installations such as small offices and shops.
