Manage dangerous currents and protect your equipment using this MCB from ABB. Its delayed thermal mechanism protects against overloads, while an electromechanical device prevents short-circuit damage. As this is a type B circuit breaker, it trips when loads between 3 and 5 times the 16A rated current are detected, making it sensitive enough to protect low-voltage electricals such as domestic appliances. An electrical and mechanical lifespan of up to 20,000 AC cycles assures you that it's a durable safety device.

• Room on front for labelling, to make it easier to organise and identify circuits
• Recessed screws and insulating housing to keep you safe during installation
• Red and green contact position indicators makes it straightforward to use
• Lockable toggle for system security

• Lighting circuits
• Low voltage equipment
• Residential buildings
• Commercial buildings

This MCB features fail-safe, bi-directional cylinder lift terminals to prevent connection errors and ensure that wires are properly secured. This makes it easier for electricians and engineers to connect it up to circuits.
