Beveiliging van elektrische circuits
Guard every circuit against overcurrent and overheat. Langir circuit protection spans DC miniature circuit breakers, snap-action thermostats, and the distribution hardware connecting them.

DC-stroomonderbreker
Circuit protection is the intentional installation of a “weak link” in an electrical circuit. This is a fuse or circuit breaker, referred to here as a circuit protection device or CPD. Langir can provide DC Circuit Breaker, Thermal Protection and Accessory. Applications such as: Railway, Power, Home and Building. IEC 60947-2, EN60947-2, GB 14048.2Ontdek DC Circuit Breaker -
Thermische bescherming
Thermische beveiliging is een methode om te hoge temperaturen te detecteren en de stroomtoevoer naar de elektronische schakelingen te onderbreken. Deze beveiliging voorkomt brand of schade aan elektronische componenten, die kan ontstaan door overmatige warmteontwikkeling in de voedingen of andere apparatuur.Ontdek Thermal Protection

Why Choose Langir Circuit Protection?
Modern electronics fail unpredictably — circuit protection is the deliberate weak link that fails safely instead. Langir approaches protection as a system: DC miniature circuit breakers interrupt overcurrent in solar arrays, battery banks, and DC distribution; snap-action thermostats disconnect power when temperature limits are breached; busbars, DIN rail, and brackets tie the installation together cleanly. Designing the protection chain from one supplier ensures ratings coordinate properly, components fit together mechanically, and a single technical contact stands behind the whole safety layer of your product.
Frequently Asked Questions About Circuit Protection
Fundamental guidance on protection types, selection, and system design.
It is the intentional installation of a controlled weak link — a breaker or thermal cutoff — that interrupts a fault before wiring melts, batteries vent, or equipment ignites.
DC miniature circuit breakers for overcurrent, snap-action thermostats for over-temperature, and supporting busbar and DIN rail hardware for professional installations.
They complement rather than compete: breakers respond to current faults like shorts and overloads, thermostats to heat buildup from blocked vents, failed fans, or ambient extremes. Robust designs often use both.
Yes, the DC breaker line is specifically engineered for the sustained arcs and unidirectional current of photovoltaic and battery applications where AC breakers underperform.
Breakers, thermostats, busbars, DIN rail, and brackets are all in-house products, letting you source a coordinated protection panel from one manufacturer.
