Product Description

ELS1 Series Surge Protective Device (SPD)ELECO modular SPD is dedicated to low-voltage power distribution, photovoltaic and industrial control systems. Adopting premium varistor core and built-in thermal disconnector, it automatically cuts off under overload and fault conditions to avoid fire and short-circuit risks.Featuring nanosecond fast response, large discharge capacity and low residual voltage, it effectively protects electrical devices from lightning surges and transient overvoltage. With V0 flame-retardant housing, it delivers excellent heat resistance and stability. Standard DIN35 pluggable design ensures easy installation and maintenance, compatible with AC/DC systems. CE-certified, factory direct supply, supporting bulk orders and OEM service.
