Solera MPCBs – Thermal-magnetic motor protection from 2.5 A to 6.3 A

Solera motor protection circuit breakers shield electric motors from sustained overloads and sudden short-circuits. Two models — GM4 (2.5–4 A) and GM6.3 (4–6.3 A) — cover small and medium-power drives in pumps, fans and machinery.

The thermal element reacts to rising current over time, while the magnetic trip opens instantly on fault peaks. A graduated front dial enables precise calibration to the motor’s rated current.

Tool-free adjustment with clearly marked scale.
Standard DIN-rail footprint for fast panel integration.
Optional auxiliaries for status signalling or PLC inputs.
Rugged housing built for industrial environments.

Solera MPCBs combine reliability, ease of use and compliance, ensuring continuous, safe motor operation across diverse sectors.
