Circuit breaker VCX GACIA SB6L 3P C 25A 6kA overcurrent protection

VCX GACIA SB6L 3P C 25A 6kA overcurrent protection is a three-pole miniature circuit breaker designed to protect electrical installations from overloads and short circuits. With a C tripping characteristic and rated current of 25 A, the device offers reliable thermal-magnetic protection for residential and light commercial distribution boards. The breaker is intended for DIN-rail mounting and allows both automatic tripping under fault conditions and manual switching for circuit isolation.

Advantages

The VCX GACIA SB6L combines a compact housing with a consistent trip curve to ensure selective operation in typical lighting, socket and small motor circuits. Its 6 kA breaking capacity provides sufficient fault-clearing capability for many low-voltage applications while the C characteristic balances sensitivity to inrush currents and prompt response to short circuits. The product supports straightforward DIN-rail installation and manual control for maintenance and circuit management.

Suitable for

• Protection of household electrical circuits including lighting and sockets
• Small commercial distribution boards and light industrial panels
• Circuits with moderate motor inrush where C characteristic is required
• DIN-rail electrical panels where compact three-pole protection is needed

Key specifications

• Poles: three-pole (3P) for simultaneous disconnection of three conductors
• Tripping characteristic: type C (thermal-magnetic)
• Rated current: 25 A
• Breaking capacity: 6 kA (short-circuit interruption capability)
• Mounting: standard DIN-rail compatible enclosure
• Operation: manual ON/OFF lever plus automatic trip on fault

How to use

Install the breaker into a compatible DIN-rail panel following local electrical codes and ensure the panel is de-energized during installation. Connect line and load conductors to the designated terminals, tightening terminals to the manufacturer's recommended torque values. Use the manual lever to switch circuits ON or OFF during maintenance; the breaker will trip automatically in the event of overload or short-circuit according to its C characteristic. After a trip, identify and clear the fault before resetting the breaker to the ON position.

Usage recommendations

Verify that circuit design and downstream protection coordination match the breaker's 25 A rating and 6 kA breaking capacity. Periodically inspect terminal tightness and signs of thermal stress, and ensure that the device is used in environments within its specified temperature and humidity ranges to maintain reliable operation.
