Breakers

Modular circuit protection for safe electrical boards

Solera circuit protection brings together the main devices required to protect, control and organise low-voltage installations. The category includes MCBs, RCDs, surge protectors, motor protection, contactors, time switches, fuse holders, pushbuttons and connection busbars.

It is designed for residential, commercial and industrial boards where reliability, modularity and fast DIN-rail installation are essential.

• Protection: solutions against overloads, short circuits, leakage currents and voltage surges.
• Control: contactors, time switches and pushbuttons for automated operation.
• Distribution: busbars and accessories for clean modular wiring.
• Applications: residential, commercial and industrial low-voltage boards.

Choosing the right protection range helps build safer boards, improves maintenance and reduces the risk of faults in everyday operation.

Our Modular Protection Range

• Miniature Circuit Breakers (MCBs): Reliable protection against overloads and short circuits, available in multiple poles (1P to 4P), various breaking capacities, and tripping curves (primarily B, C, and D) to suit different load types.
• Residual Current Circuit Breakers (RCCBs / RCDs): High-sensitivity earth leakage protection (such as 30mA and 300mA) in Type AC and Type A configurations to prevent electrical shocks and fire hazards.
• Residual Current Breakers with Overcurrent (RCBOs): Space-saving, combined protection units that integrate MCB and RCCB functions into a single compact module, maximizing panel efficiency.
• Surge Protection Devices (SPDs): Advanced transient and permanent overvoltage protectors designed to shield sensitive electronic equipment from voltage spikes and lightning strikes.
• Molded Case Circuit Breakers (MCCBs): High-capacity breakers engineered to manage and protect heavy-duty industrial electrical distribution boards.
