Frequently Asked Questions

AI
Type B MCBs trip quickly on small overloads and are ideal for domestic lighting and socket circuits. Type C MCBs tolerate higher inrush currents, making them suitable for motors, transformers, and commercial equipment where sudden power spikes occur during startup.
Lockout kits are essential for electricians performing maintenance. They physically prevent the breaker from being switched on, ensuring safety during repairs. If you are simply replacing a breaker for operational use, a standard MCB is sufficient; lockout devices are for safety isolation protocols.
An IP65 rating indicates the breaker is dust-tight and protected against low-pressure water jets from any direction. This makes it suitable for outdoor installations or damp environments, such as garden sheds or industrial areas exposed to weather, unlike standard indoor MCBs.
