LSP FLP12,5-275 & FLP7-275 DIN-Rail AC Type 1+2 Surge Protection Devices deliver reliable surge protection against lightning, heavy surge currents, and transient overvoltages, ideal for residential, commercial, industrial, and solar PV AC systems.
This DIN-Rail AC Type 1+2 surge protection device (SPD) safeguards electrical installations against lightning strikes by efficiently discharging surge currents and preventing them from reaching connected equipment.
The Type 1+2 surge protection device (SPD) must be properly installed to ensure effective protection. It should be connected in parallel on the main distribution board, with a dedicated circuit breaker or fuse installed upstream to provide backup protection and ensure safe operation.
The AC Type 1+2 surge protection device (SPD) is engineered to handle lightning currents with both 10/350 µs and 8/20 µs waveforms, providing reliable protection for residential, commercial, and industrial electrical systems.
The AC Type 1+2 surge protection device (SPD) with remote signaling terminals is designed for convenient remote monitoring and management.
The Type 1+2 DIN-Rail AC surge protection device (SPD) adopts a pluggable housing design, enabling easy replacement and maintenance.
A Type 1+2 surge protection device (SPD) combines the functions of both Type 1 SPD (protection against direct lightning strikes, typically installed at the service entrance) and Type 2 SPD (protection against switching surges and residual lightning energy, usually installed in distribution boards). It ensures comprehensive protection for both residential and industrial applications.
Yes. A Type 1+2 surge protection device (SPD) is designed to handle high-energy lightning currents as well as low-energy switching transients. This makes a Type 1+2 SPD a versatile solution, combining the functions of a Type 1 surge protector and a Type 2 SPD in one unit.
Choose a Type 1+2 SPD (also called a Type 1 type 2 surge protection device) if the installation site is exposed to lightning strikes or connected to outdoor overhead power lines. For indoor-only networks or areas with low lightning risk, a Type 2 surge protector is often more cost-effective and sufficient.
LSP Type 1+2 SPDs are equipped with a visual status indicator window, allowing you to quickly determine whether the module needs replacement.
These Type 1+2 SPDs use high-energy MOVs for rapid response. The impulse current (10/350 µs) can reach 12.5 kA, and the nominal discharge current (8/20 µs) can reach 20 kA, effectively protecting critical equipment.
Absolutely. They provide reliable protection for control cabinets, inverters, servers, surveillance systems, and other critical devices, ensuring all-weather, continuous surge protection.
