What is Breaking Capacity in Low-Voltage Switchgear?
How Gorlan India’s AC Compact Switch Disconnectors Ensure Electrical Safety:
In today’s power distribution systems, electrical safety isn’t just best practice — it’s essential. One key factor in low-voltage switchgear safety is breaking capacity.
But what exactly is breaking capacity, and why is it so important? More importantly, how do Gorlan India’s AC Switch Disconnectors, like the S3 and S5 series, meet this need with precision engineering? Let’s explore.
What is Breaking Capacity?
Breaking capacity (or short-circuit breaking capacity) is the maximum current that a switching device — such as a circuit breaker or switch disconnector — can interrupt safely during a fault condition without suffering damage.
It’s typically expressed in kA RMS (kiloamperes Root Mean Square) and plays a vital role in preventing:
Equipment damage
Fire hazards
Arc faults
Electrical downtime
For engineers and facility managers, selecting switchgear with the correct breaking capacity ensures personnel safety, system reliability, and compliance with global electrical standards.

Why Breaking Capacity Matters in Low-Voltage Applications
Low-voltage panels, especially in industrial and commercial buildings, are exposed to high fault currents due to:
Equipment loads fluctuations
Motor starting surges
Short-circuits and overloads
If the switchgear can’t handle these fault levels, the result could be:
Dangerous arc blasts
Complete panel failure
Damage to upstream/downstream components
That’s why IEC/EN 60947-3 mandates minimum breaking capacity ratings for switch-disconnectors used in low-voltage systems.
